An ophthalmic artery pseudoaneurysm is a small, dangerous bulge that forms in the ophthalmic artery, the blood vessel that supplies the eye and the tissues around it. The bulge is not a true ballooning of the vessel wall. Instead, it is a leak through a wall injury that becomes contained by the surrounding tissues. That is why it is called a “pseudo” (false) aneurysm. The sac fills with blood, connects back to the artery through a narrow opening, and can rupture, bleed, or throw clots. This can threaten sight or even life. Doctors treat it as an emergency or an urgent condition. PMCEyeWiki

An ophthalmic artery pseudoaneurysm is a dangerous, abnormal bulge that forms in the wall of the ophthalmic artery (the artery that supplies the eye) after the wall has been injured or weakened. Because the wall is torn, the bulge is not a true, layered artery any more—it is a blood-filled sac held together by clot and nearby tissues. Pseudoaneurysms can enlarge, leak, or rupture, causing sudden nosebleeds, eye symptoms, or even brain bleeding. They are rare, and they most often follow head/face trauma or surgery around the orbit and sinuses; far less often they are linked to infection (“mycotic” or infectious intracranial aneurysm). Definitive diagnosis is usually made with catheter angiography (digital subtraction angiography, DSA), and treatment is typically endovascular (from inside the blood vessel) or surgical to stop blood flow into the sac and prevent rupture, while trying to protect vision.

A pseudoaneurysm is different from a “true” aneurysm. A true aneurysm involves all normal layers of the artery stretching outward. A pseudoaneurysm lacks one or more normal layers, so the “wall” is weak scar tissue or nearby structures. Because the wall is weak, the risk of rupture and bleeding is higher than with many true aneurysms. This is especially important inside the head or around the eye, where there is no room for extra blood or pressure. PMC

This condition matters because it can cause sudden heavy nosebleeds, vision loss, painful eye pressure or swelling, and occasionally bleeding around the brain (subarachnoid hemorrhage). These problems may appear days to weeks after a head, facial, or surgical injury. That delay can be confusing and dangerous if the diagnosis is missed. Case reports describe ophthalmic artery pseudoaneurysms presenting with recurrent epistaxis (nosebleeds), proptosis (bulging eye), and even subarachnoid hemorrhage—and they improve after endovascular closure of the pseudoaneurysm. ThiemePubMedCanadian Journal of Ophthalmology

The ophthalmic artery branches off the internal carotid artery just inside the skull and then travels with the optic nerve into the orbit. It gives off many small branches to the retina, the optic nerve, the eyelids, and the sinuses. Because it lies near the paranasal sinuses and the skull base, it can be injured by facial trauma or by endoscopic sinus and skull-base surgery. When injured, blood can escape into the orbit or the nose, leading to visible eye changes or nosebleeds. PMCCanadian Journal of Ophthalmology

Types

Doctors may group ophthalmic artery pseudoaneurysms in a few simple ways:

1. By cause (etiology)

   • Traumatic: After blunt blows to the eye/face, penetrating injuries, or skull-base fractures. PMCThieme

   • Iatrogenic (procedure-related): After endoscopic sinus surgery, endoscopic skull-base or optic canal procedures, or other operations/interventions near the orbit and anterior skull base. Canadian Journal of OphthalmologyFrontiers

   • Infectious (“mycotic”): From bacterial or fungal infections that weaken the artery wall (for example, severe sinus infection spreading to vessels). PMC

   • Inflammatory/vasculitic: From vessel inflammation (e.g., systemic vasculitis) damaging the wall. PMC

   • Radiation-related: Prior radiotherapy to the orbit or skull base damaging vessel walls over time. PMC

   • Neoplastic erosion: Tumors eroding into the artery. PMC

   • Idiopathic: No clear trigger found.

2. By location

   • Intraorbital (inside the eye socket). These often cause local eye signs like swelling, proptosis, or retinal problems. Lippincott Journals

   • Intracranial/intradural origin of the ophthalmic artery (near its takeoff from the carotid). These may cause headache or subarachnoid hemorrhage. PubMed

3. By shape / wall behavior

   • Saccular false sac (a globular pouch with a narrow neck from the artery).

   • Dissecting-type (blood tracks within a torn wall with a pseudoaneurysm pouch). PMC

4. By timing

   • Immediate (noticed right after injury/surgery).

   • Delayed (appears days–weeks later as the false sac enlarges). PMC

Causes

1. Blunt orbital trauma (a hit to the eye/face can tear the ophthalmic artery). PMC

2. Penetrating orbital injury (sharp object causing a direct arterial cut). Thieme

3. Skull-base or orbital wall fractures (bone fragments can nick the artery). Lippincott Journals

4. Endoscopic sinus surgery (ESS) near the ethmoid/sphenoid (surgical instruments or heat injure the artery or a branch). Canadian Journal of Ophthalmology

8. Catheter or guidewire-related arterial trauma during neuro-interventional procedures. PMC

9. Severe bacterial sinusitis spreading to vessels (infection weakens the wall). PMC

10. Invasive fungal sinusitis (e.g., mucormycosis) eroding the artery. PMC

11. Systemic vasculitis (vessel inflammation damages the wall, predisposing to rupture). PMC

12. Radiation injury to skull base/orbit vessels causing delayed wall breakdown. PMC

13. Tumor erosion from sinonasal or orbital malignancies into the arterial wall. PMC

Diagnostic tests

A) Physical exam (what the clinician sees and checks at the bedside)

1. Vital signs (pulse, blood pressure) to detect shock or ongoing bleeding.

2. Focused nose and sinus exam to look for active or old bleeding points.

3. External eye inspection for bulging, swelling, redness, or bruising.

4. Visual acuity testing (reading chart) to measure any change in sight.

5. Pupils and afferent pupillary defect (APD) to check optic-nerve function.

6. Confrontation visual fields to screen for missing parts of the visual field.

7. Fundus (retina) exam to look for retinal artery occlusion or optic-disc swelling.

8. Auscultation over the orbit with a stethoscope for a bruit (whooshing sound).

9. Exophthalmometry (measuring eye protrusion) to document proptosis.

10. Anterior rhinoscopy or endoscopic nasal exam (ENT scope) to search for bleeding sources and pulsatile lesions in the nasal cavity (performed carefully by specialists). These bedside findings guide imaging but do not rule the condition in or out by themselves. Canadian Journal of Ophthalmology

B) Manual tests (simple bedside maneuvers—specialist-only when risky)

Important: these maneuvers are physician-directed. They are not for patients to try.

11. Gentle orbital palpation to feel for a tender, pulsatile fullness (avoiding pressure that might provoke bleeding).

12. Observation during Valsalva (bearing down) to see if pulsation or fullness increases, suggesting a vascular lesion.

13. Brief carotid compression test may be used in controlled settings by specialists to see if a bruit or pulsation lessens, suggesting an arterial connection. This test is avoided in most patients because it can reduce brain blood flow and is unsafe outside expert hands. These bedside clues can raise suspicion but definitive diagnosis always needs imaging. PMC

C) Laboratory & pathological tests (to look for contributors or complications)

14. Complete blood count (CBC) to check anemia from bleeding and look for infection markers.

15. Coagulation profile (PT/INR, aPTT) to uncover bleeding risks or medication effects.

16. Inflammatory markers (CRP, ESR) if vasculitis or infection is suspected.

17. Blood cultures when fever or severe sinus infection suggests a mycotic pseudoaneurysm.

18. Microbiology or pathology of sinus/orbital tissue, if surgery is done, to confirm infection or tumor as a cause. These lab tests do not diagnose the pseudoaneurysm, but they identify why it formed and help tailor treatment (e.g., antibiotics, antifungals, or immunosuppressive therapy alongside vessel repair). PMC

D) Electrodiagnostic tests (to measure eye nerve and retina function)

19. Visual evoked potentials (VEP) evaluate how well signals travel from the retina to the brain through the optic nerve.

20. Electroretinography (ERG) measures retinal cell function when retinal blood flow may be compromised.

21. Electro-oculography (EOG) assesses the retinal pigment epithelium and ocular motility coupling. These tests help quantify vision pathway damage but do not identify the pseudoaneurysm itself. They complement imaging and clinical decisions. (General neuro-ophthalmic practice.) PMC

E) Imaging tests (the heart of diagnosis)

22. CT scan of the orbits/sinuses with contrast shows fractures, surgical changes, and abnormal enhancing masses along the ophthalmic artery’s course. It is fast and widely available. Canadian Journal of Ophthalmology

23. CTA (CT angiography) maps arteries quickly and may show a small, round “contrast-filled sac” connected to the ophthalmic artery. It is excellent for planning urgent care. PMC

24. MRI of brain and orbits with MRA shows soft tissues, optic nerve, and any blood products. MRA can reveal the lesion, but very small pseudoaneurysms can be missed. PMC

25. DSA (digital subtraction angiography) is the gold standard. It shows the exact vessel of origin, the neck, and blood flow in real time. A pseudoaneurysm often fills late, has stagnant contrast, and may lack a normal neck; DSA also allows treatment during the same session. PMC

26. 3D rotational angiography further defines the neck and relationship to the optic nerve and branches, improving safety of endovascular treatment. PMC

27. High-resolution vessel-wall MRI (black-blood imaging) can show wall injury or inflammation and helps distinguish true aneurysm from pseudoaneurysm in complex cases. Frontiers

28. Color Doppler orbital ultrasonography can demonstrate a pulsatile, turbulent flow focus in the orbit and help in follow-up, especially for intraorbital lesions. (Adjunctive; operator-dependent.) Lippincott Journals

29. Time-resolved CTA/MRA (4D angiography), when available, can show the dynamics of filling and draining, which helps differentiate high-flow lesions. (Adjunctive, center-dependent.) PMC

Non-pharmacological treatments

These steps do not cure a pseudoaneurysm but help stabilize you, reduce risks, and prepare you for definitive repair. Each item explains What, Why, and How it helps.

1. Urgent specialist referral (ER, neurosurgery/interventional neuroradiology/ENT).
   Because rupture can be catastrophic and diagnosis requires angiography, early transfer to a center with endovascular capability is vital. This speeds imaging and treatment, lowering the chance of major bleeding or vision loss. PMC

2. Nasal first-aid for active nosebleed.
   Sit forward, pinch the soft nose for 10–15 min, and apply a topical vasoconstrictor if advised. This limits blood loss and aspiration while you seek help. Persistent or recurrent bleeding still needs hospital care. ERN ITHACA

3. Avoid nose blowing, heavy lifting, or straining.
   These increase intranasal and arterial pressure, which can trigger rebleeding from a fragile pseudoaneurysm wall. Stool softeners and cough control reduce straining. (Supportive standard in epistaxis and aneurysm care.) ERN ITHACA

4. Head elevation (especially during bleeding episodes).
   Slightly raising the head reduces venous pressure in the head/neck and can modestly reduce oozing. It’s a low-risk, comfort-oriented measure used alongside definitive care. PMC

5. Protect the orbit (eye shield, no rubbing).
   Minimizes mechanical irritation and prevents accidental pressure on the orbit that could disturb fragile clot within a pseudoaneurysm.

6. Blood pressure control (lifestyle).
   Restrict sodium (aim <2,300 mg/day, ideally ~1,500 mg/day), follow DASH/Mediterranean-style patterns, stay active, and limit alcohol. Lowering BP reduces mechanical stress on the pseudoaneurysm and improves overall vascular health. www.heart.orgPMCAmerican Heart Association Journals

7. Stop smoking (and avoid vaping).
   Smoking injures vessel lining and worsens healing. Quitting supports endothelial recovery and lowers peri-procedural risk.

8. Medication review (with clinicians).
   Some drugs/supplements (e.g., anticoagulants, high-dose NSAIDs, fish-oil, ginkgo) can increase bleeding risk. Your team will decide what to stop or bridge before angiography/stenting. (General peri-procedural hemostasis principle.)

9. Infection control and dental care.
   Because a small subset of intracranial aneurysms are infectious, treating sinus/dental infections promptly and maintaining dental hygiene lowers bacteremia risk. PMC

10. Eye-safe activity plan.
    Until the lesion is treated, avoid contact sports and activities with risk of head impact. This limits re-injury of fragile vessels.

11. Follow-up imaging as advised.
    Traumatic pseudoaneurysms can enlarge with time. Scheduled CTA/MRA/DSA helps catch growth and plan timely repair. PMC

12. Manage coughing/allergies/constipation.
    Less Valsalva = fewer pressure spikes. Simple steps (hydration, fiber, prescribed stool softener, allergy management) help.

13. Sleep and stress control.
    Good sleep and stress management lower sympathetic surges and BP peaks, trimming bleeding risk.

14. Protective driving/work restrictions.
    If you have vision changes or risk of sudden bleed, temporary driving/work limits keep you and others safe.

15. Iron and volume repletion if anemic (medical guidance).
    Correcting anemia from nosebleeds improves oxygen delivery while you proceed to repair.

16. Humidified air & saline gels (if crusting/epistaxis).
    Keeps nasal mucosa moist, reducing spontaneous cracking/bleeds while awaiting treatment. ERN ITHACA

17. Emergency plan.
    Know which hospital can perform neuro-endovascular care; have transport options prepared.

18. Vaccinations up to date.
    Staying current (e.g., influenza, pneumococcal per age/risks) helps prevent infections that could complicate recovery or—rarely—seed vessels. (General infectious aneurysm principle.) PMC

19. Multidisciplinary case review.
    Combining neurosurgery, interventional neuroradiology, and ENT/ophthalmology ensures a plan that balances bleed control and vision preservation. PMC

20. Patient education.
    Understanding warning signs and medication instructions improves adherence and outcomes—especially if a stent and dual antiplatelet therapy are planned.

Drug treatments

Key point: Medicines don’t “shrink” the pseudoaneurysm. They are used to control bleeding, optimize blood pressure, treat infection when present, and prevent stent thrombosis if a stent/flow diverter is placed. Doses are typical adult examples; individual plans vary and your team’s protocol prevails.

1. Aspirin (antiplatelet; DAPT component when stents are used)
   Dose/Timing: Commonly 81–325 mg once daily; started before and continued after flow-diverter/stent treatment per protocol.
   Purpose/Mechanism: Inhibits COX-1 → reduces thromboxane A2 → lowers platelet clotting, preventing in-stent thrombosis.
   Side effects: Bleeding, dyspepsia; rarely ulcer/hemorrhage. Never start/stop without your specialist’s plan.

2. Clopidogrel (P2Y12 inhibitor; DAPT partner)
   Dose/Timing: Often a loading dose (e.g., 300–600 mg) then 75 mg daily, guided by local testing/protocols.
   Purpose/Mechanism: Blocks platelet ADP receptor → prevents platelet aggregation on flow-diverter/stent.
   Side effects: Bleeding, bruising; variable responsiveness.

3. Ticagrelor (alternative P2Y12 inhibitor)
   Dose/Timing: Typically 90 mg twice daily (after a loading dose), where used.
   Purpose/Mechanism: Reversible P2Y12 blockade with more consistent effect than clopidogrel in some patients.
   Side effects: Bleeding, dyspnea. (Choice depends on center protocols.)

4. Prasugrel (alternative P2Y12 inhibitor, selected cases)
   Dose/Timing: Often 10 mg daily after loading; used in specific scenarios.
   Purpose/Mechanism: Potent irreversible P2Y12 inhibition when clopidogrel response is inadequate.
   Side effects: Higher bleeding risk—specialist decision only.

5. Intraprocedural heparin (anticoagulant during angiography)
   Dose/Timing: Given IV during endovascular procedures to keep the catheterized artery from clotting; dose guided by activated clotting time.
   Purpose/Mechanism: Temporarily prevents catheter-related thrombosis.
   Side effects: Bleeding; reverses when infusion stops. (Standard endovascular practice.) neuroimaging.theclinics.com

6. Tranexamic acid (TXA) for problematic anterior epistaxis
   Dose/Timing: Common ED regimen: 500 mg TXA solution on gauze, applied topically inside the bleeding nostril; sometimes repeated.
   Purpose/Mechanism: Antifibrinolytic—stabilizes clots on oozing mucosa; helpful adjunct while you proceed to definitive repair.
   Side effects: Local irritation; systemic dosing has clotting cautions, so topical use is preferred for nosebleeds. PubMedBoston University Medical Campus

7. Culture-directed IV antibiotics (when infection causes the aneurysm)
   Dose/Timing: 4–6 (sometimes 6–8) weeks of IV antibiotics tailored to cultures (e.g., for endocarditis-related infectious intracranial aneurysm).
   Purpose/Mechanism: Eradicates the organism weakening the artery wall; endovascular/surgical therapy is added if the aneurysm persists or ruptures.
   Side effects: Drug-specific; labs and imaging monitor response. NCBIPMC

8. BP-lowering medicines (individualized)
   Dose/Timing: Labetalol, nicardipine, or your usual antihypertensives as guided by clinicians.
   Purpose/Mechanism: Reduces arterial wall stress and rebleed risk, especially if there’s associated subarachnoid hemorrhage or ongoing epistaxis.
   Side effects: Drug-specific (light-headedness, slow pulse, etc.). www.heart.org

9. Acetaminophen for pain
   Dose/Timing: Typically 500–1,000 mg every 6–8 h (max 3,000–4,000 mg/day, accounting for combinations).
   Purpose/Mechanism: Analgesia without platelet effects (preferred over NSAIDs when bleeding is a concern).
   Side effects: Liver toxicity if overdosed; avoid with heavy alcohol.

10. Saline gels/oxymetazoline (short course) for nasal care
    Dose/Timing: Saline as needed; oxymetazoline limited (commonly ≤3 days) to avoid rebound.
    Purpose/Mechanism: Moisturizes crusted mucosa and causes local vasoconstriction to slow oozing while definitive care proceeds.
    Side effects: Rebound congestion (with prolonged oxymetazoline). ERN ITHACA

Dietary molecular supplements

No supplement can heal a pseudoaneurysm. Discuss every supplement with your procedural team, especially before/after stent or embolization, because some increase bleeding risk.

1. Omega-3 (EPA+DHA) — about 1 g/day of combined EPA+DHA from food/supplements if approved by your clinician.
   Function/Mechanism: Anti-inflammatory, triglyceride-lowering; may slightly affect platelets.
   Note: Potential bleeding interaction—clear with your team before procedures or while on DAPT. Office of Dietary Supplements

2. Vitamin C — 75–90 mg/day (do not exceed 2,000 mg/day).
   Function: Collagen synthesis; general connective-tissue support.
   Mechanism: Cofactor in collagen cross-linking.
   Caution: GI upset at high doses; avoid mega-doses. Office of Dietary Supplements+1

3. Dietary nitrate (e.g., beetroot juice) — amounts used in studies vary; many use ~70–140 mL of concentrated juice/day.
   Function: Modest BP lowering via nitric-oxide pathway; may improve endothelial function.
   Mechanism: Nitrate → nitrite → nitric oxide vasodilation.
   Caution: Interacts with antiseptic mouthwash (kills oral bacteria needed for conversion). PMC

4. Magnesium — ~200–400 mg/day from diet/supplement if needed; avoid with kidney disease.
   Function: BP support in deficiency.
   Mechanism: Vascular smooth-muscle relaxation and improved endothelial function.
   Evidence: Meta-analyses show small BP reductions. PubMed+1

5. Coenzyme Q10 — 100–200 mg/day (adjunct).
   Function/Mechanism: Mitochondrial cofactor; may modestly lower SBP in cardiometabolic conditions.
   Caution: Interactions with anticoagulants possible. PubMed

6. Vitamin D — 600–800 IU/day typical; correct deficiency per labs.
   Function: Bone/immune support; correct deficiency for general health (not aneurysm-specific).
   Mechanism: Nuclear receptor modulation. (Use per clinician advice; evidence for BP effect is mixed.)

7. Potassium-rich food pattern (bananas, beans, leafy greens) rather than pills unless prescribed.
   Function: Helps BP control when kidneys are normal.
   Mechanism: Counterbalances sodium’s effect on vessels. American Heart Association Journals

8. Flavonoid-rich foods (berries, cocoa in moderation).
   Function/Mechanism: Antioxidant and endothelial support; part of heart-healthy patterns. American Heart Association Journals

9. Fiber (soluble) from oats, legumes, psyllium.
   Function: Lipid and glycemic control supporting vascular health.
   Mechanism: Bile acid binding and slowed absorption. American Heart Association Journals

10. Overall DASH/Mediterranean eating pattern (not a pill, but the most evidence-based “supplement” you can adopt).
    Function: Lowers blood pressure and improves vascular outcomes.
    Mechanism: High in vegetables/fruits/whole grains; low sodium and low processed foods. NHLBI, NIH

Regenerative / stem-cell drugs

There are no FDA-approved stem-cell or “regenerative” drugs to treat ophthalmic artery pseudoaneurysm, and no proven “immunity booster” drug for it. Below is the current state of play so you can avoid misinformation.

1. Stem-cell therapies for intraocular disease (general status).
   Function/mechanism proposed: Replace or support damaged retinal/optic tissues via trophic factors or cell replacement.
   Reality: No FDA-approved ocular stem-cell products; clinical trials are ongoing for retinal conditions, not pseudoaneurysm. Use only in regulated trials. PMCHarvard Stem Cell Institute

2. MSC-derived exosomes (experimental).
   Mechanism: Paracrine delivery of anti-inflammatory/anti-apoptotic signals.
   Status: Investigational in eye diseases; not an approved therapy for vascular pseudoaneurysm. MDPI

3. Optic nerve/retinal stem-cell research programs.
   Mechanism: Attempted replacement of retinal ganglion cells or support cells.
   Status: Early-stage research; no approved clinical product for aneurysm-related injury. PMC

4. Corneal stem-cell therapies (limbal).
   Mechanism: Surface eye repair after chemical/thermal injury.
   Status: Not targeted to intra-cranial/ophthalmic artery pathology; unrelated to pseudoaneurysm repair. Mass General Brigham

5. Cell therapy for peripheral ischemia (PAD) — not for intracranial aneurysm.
   Status: Experimental in limb ischemia; no role in repairing a cranial pseudoaneurysm. Verjournal

6. FDA safety note.
   Bottom line: Be cautious with clinics marketing “stem-cell cures”; many products are unapproved and can be unsafe. U.S. Food and Drug Administration

Procedures/Surgeries

1. Endovascular coil embolization
   What: A microcatheter is navigated into the pseudoaneurysm and tiny coils are packed inside to promote clotting and seal it.
   Why: Definitive exclusion from the circulation with an eye toward preserving the ophthalmic artery whenever feasible. PMC

2. Liquid embolic occlusion (e.g., Onyx/NBCA)
   What: A controlled injection of a liquid that solidifies to plug the sac or the small branch feeding it.
   Why: Useful when the neck is unfavorable for coils or the lesion is tiny/fragile. (Technique described across traumatic pseudoaneurysm literature.) KJR Online

3. Flow-diverter stent reconstruction
   What: A high-metal-coverage stent placed across the parent artery to redirect flow away from the pseudoaneurysm, promoting thrombosis over weeks.
   Why: Reconstructs the vessel when direct coiling isn’t feasible. Requires dual antiplatelet therapy and careful assessment because covering the ophthalmic origin can threaten retinal blood flow.

4. Parent artery occlusion (ophthalmic artery or ICA segment)
   What: Planned, permanent closure of the parent artery after balloon test occlusion proves the brain/eye can tolerate it (or if vision is already non-recoverable).
   Why: A reliable curative option when preserving the artery is impossible or unsafe. PMC+1

5. Open surgical trapping/clipping (selected cases)
   What: Direct surgical exposure to clip, trap, or bypass around the lesion.
   Why: Rarely chosen today; considered when anatomy or prior interventions preclude endovascular therapy and vision or mass-effect issues demand decompression. PMC

Ways to prevent problems

1. Treat the pseudoaneurysm definitively—don’t “watch and wait.” PMC

2. Control blood pressure (diet, activity, meds as prescribed). American Heart Association Journals

3. Quit smoking; avoid nicotine/vaping.

4. Wear protective gear (helmets/seatbelts) to prevent head/face trauma.

5. Promptly treat sinus/dental infections; maintain dental hygiene. PMC

6. Coordinate all medications before/after procedures (especially blood thinners and supplements).

7. Adhere strictly to dual antiplatelet therapy if a stent/flow-diverter is placed.

8. Keep follow-up imaging appointments to confirm durable occlusion. PMC

9. Manage chronic conditions (diabetes, lipids, sleep apnea) that impair vascular healing.

10. Build an emergency plan for any return of nosebleed or sudden vision change.

---

When to see a doctor

• Right now / ER: New one-eye vision loss, sudden severe headache, profuse or recurrent nosebleed, or painful eye bulging—especially within weeks after head/face trauma or sinus/orbital surgery. PMC

• Urgent clinic/hospital: Persistent low-grade nosebleeds, new double vision, new eye pressure/pain, or pulsating noise in one eye/orbit.

• Routine (after treatment): Any change in vision, new headaches, medication side-effects, or if you miss doses of antiplatelet therapy after stenting.

What to eat vs. what to avoid

1. Aim for a DASH/Mediterranean pattern: vegetables, fruits, beans, whole grains, nuts, fish. Supports BP and vessel health. American Heart Association Journals

2. Sodium: Keep <2,300 mg/day, moving toward ~1,500 mg/day if possible. www.heart.org

3. Potassium-rich foods (if kidneys are healthy): leafy greens, beans, bananas, potatoes. Helps offset sodium. American Heart Association Journals

4. Moderate alcohol (or avoid). Helps BP control. American Heart Association

5. Add natural nitrate foods (beetroot, spinach) in normal culinary amounts if your team approves—may modestly help BP. PMC

6. Healthy fats (olive oil, nuts; minimize trans/saturated fats). Supports overall vascular health. American Heart Association Journals

7. Adequate protein from fish/legumes/poultry; limit processed meats. American Heart Association Journals

8. Be cautious with “bleeding-risk” supplements (fish-oil capsules, ginkgo, garlic) before/after endovascular procedures or while on DAPT—clear with your team. Office of Dietary Supplements

9. Hydrate and use fiber to avoid constipation/straining.

10. Avoid highly salted, ultra-processed foods (soups, chips, fast foods); they spike sodium and BP. www.heart.org

Frequently Asked Questions

1) Is a pseudoaneurysm the same as an aneurysm?
No. A true aneurysm has all vessel wall layers stretched; a pseudoaneurysm is a leak contained by clot and nearby tissue, so it is more fragile. PMC

2) Can it go away by itself?
Rarely, small ones may thrombose, but counting on that is unsafe. Most need definitive repair because of growth and rupture risk. PMC

3) What symptoms should worry me most?
Recurrent nosebleeds, new one-eye vision loss, bulging eye, or sudden severe headache after trauma or surgery. Seek emergency care. PMC

4) Which test is most accurate?
Catheter angiography (DSA) defines the lesion best and allows treatment during the same session. CTA/MRA are helpful screens. PMC

5) Will treatment cost me my vision?
Teams aim to seal the pseudoaneurysm and preserve the ophthalmic artery. Some strategies (e.g., covering the artery with a flow-diverter) carry retinal ischemia risk, weighed carefully against rupture risk.

6) What if my pseudoaneurysm is from infection?
You’ll need weeks of IV antibiotics, sometimes plus endovascular/surgical repair if it persists or ruptures. NCBI

7) Do blood thinners help?
Not to treat the pseudoaneurysm itself. Antiplatelets are used only when stents are placed (to prevent stent clotting). Otherwise, blood-thinning may increase bleeding risk and is avoided unless specifically indicated.

8) How soon is treatment needed?
Quick evaluation is essential. Many cases are treated promptly to prevent rupture or further bleeding. Some traumatic lesions enlarge after a delay, so follow-up imaging is key. PMC

9) What is recovery like?
Most patients go home within days after endovascular therapy. You’ll follow activity restrictions, take medicines exactly as prescribed (especially DAPT after stenting), and return for follow-up scans.

10) Can I fly?
After successful embolization and once your team clears you (often after follow-up imaging), routine air travel is usually fine. Always confirm timing with your specialist.

11) Will I need lifelong medicines?
If you received a flow-diverter/stent, you’ll need months of dual antiplatelet therapy, then usually single antiplatelet therapy—duration varies by center and imaging results.

12) Could it come back?
Recurrence is uncommon when the pseudoaneurysm is fully excluded, but surveillance imaging ensures it stays closed. PMC

13) Are there approved stem-cell or “regenerative” drugs for this?
No—none are approved for ophthalmic artery pseudoaneurysm; be cautious of marketing claims. PMCU.S. Food and Drug Administration

14) What about herbs and supplements?
Discuss all supplements with your team; some raise bleeding risk around procedures or interact with antiplatelets. Office of Dietary Supplements

15) What lifestyle change matters most?
Blood pressure control (diet + activity + medications if needed) and smoking cessation—these support vessel health and safer recovery. American Heart Association Journals
