Convexal Subarachnoid Hemorrhage

Convexal subarachnoid hemorrhage (cSAH) is bleeding that occurs in the space between the brain and the thin tissues covering it, specifically in the convexity of the brain’s surface.

Types of Convexal Subarachnoid Hemorrhage

• Traumatic cSAH: Caused by head injury.
• Non-traumatic cSAH: Due to underlying conditions like cerebral amyloid angiopathy or vascular malformations.

Causes of Convexal Subarachnoid Hemorrhage

1. Head Trauma: Falls, accidents.
2. Cerebral Amyloid Angiopathy: Deposits of amyloid protein in brain blood vessels.
3. Arteriovenous Malformations: Abnormal connections between arteries and veins in the brain.
4. Cerebral Aneurysms: Weakness in blood vessel wall leading to bulging.
5. High Blood Pressure: Hypertension can stress blood vessel walls.
6. Anticoagulant Use: Medications that prevent blood clotting.
7. Brain Tumors: Abnormal growths in brain tissue.
8. Coagulopathy: Disorders affecting blood clotting.
9. Vascular Infections: Infections affecting blood vessels.
10. Cocaine Use: Illicit drug that can lead to vessel damage.

Symptoms of Convexal Subarachnoid Hemorrhage

1. Severe Headache: Sudden, intense headache.
2. Nausea and Vomiting: Due to increased pressure in the brain.
3. Stiff Neck: Neck stiffness.
4. Altered Mental Status: Confusion or decreased consciousness.
5. Seizures: Abnormal electrical activity in the brain.
6. Vision Changes: Blurred vision or double vision.
7. Weakness or Numbness: Especially on one side of the body.
8. Speech Difficulty: Slurred speech or inability to speak.
9. Sensitivity to Light: Photophobia.
10. Loss of Consciousness: Fainting or coma.

Diagnostic Tests for Convexal Subarachnoid Hemorrhage

1. CT Scan: Initial imaging test to detect bleeding in the brain.
2. MRI: Provides detailed images of brain structures.
3. Cerebral Angiography: Shows blood vessel abnormalities.
4. Lumbar Puncture (Spinal Tap): Checks for blood in cerebrospinal fluid.
5. EEG (Electroencephalogram): Records brain’s electrical activity.
6. Blood Tests: Check for clotting disorders or infections.
7. Neurological Examination: Assesses brain function and reflexes.
8. Ophthalmoscopy: Examines the back of the eye for signs of bleeding.
9. X-rays: May be used to detect fractures or foreign objects.
10. PET Scan: Measures brain activity and blood flow.

Non-Pharmacological Treatments for Convexal Subarachnoid Hemorrhage

1. Observation and Monitoring: In a hospital setting.
2. Bed Rest: Minimize physical exertion.
3. Hydration: Intravenous fluids to maintain blood volume.
4. Temperature Control: Cooling measures to prevent fever.
5. Oxygen Therapy: Ensure adequate brain oxygenation.
6. Physical Therapy: Rehabilitation exercises if weakness occurs.
7. Speech Therapy: Helps with language or communication difficulties.
8. Nutritional Support: Feeding tubes if swallowing is impaired.
9. Counseling: Emotional support for patients and families.
10. Surgical Drainage: If there’s buildup of cerebrospinal fluid.

Drugs Used in Treatment of Convexal Subarachnoid Hemorrhage

1. Anticonvulsants: Prevent seizures (e.g., phenytoin).
2. Analgesics: Pain relief (e.g., acetaminophen).
3. Antiemetics: Control nausea and vomiting (e.g., ondansetron).
4. Stool Softeners: Prevent constipation due to bed rest (e.g., docusate).
5. Antihypertensives: Lower blood pressure if elevated (e.g., labetalol).
6. Antibiotics: Treat infections if present (e.g., ceftriaxone).
7. Diuretics: Manage fluid balance (e.g., furosemide).
8. Anticoagulants or Antiplatelets: Prevent clot formation (e.g., heparin).
9. Neuroprotective Agents: Limit brain damage (e.g., mannitol).
10. Sedatives: Manage agitation or anxiety (e.g., lorazepam).

Surgeries for Convexal Subarachnoid Hemorrhage

1. Clipping: Surgical placement of a clip to seal off an aneurysm.
2. Coiling: Insertion of coils into an aneurysm to block blood flow.
3. Craniotomy: Removal of blood clot or repair of vessel.
4. Burr Hole: Small hole drilled into the skull to relieve pressure.
5. Ventriculostomy: Drainage of excess cerebrospinal fluid.
6. Craniectomy: Removal of part of the skull to reduce pressure.
7. Embolization: Injection of a substance to block abnormal vessels.
8. Shunt Placement: Redirecting fluid to another part of the body.
9. Endoscopic Surgery: Minimally invasive procedures for clot removal.
10. Sterotactic Radiosurgery: Precise radiation to treat vascular abnormalities.

Prevention of Convexal Subarachnoid Hemorrhage

1. Control Blood Pressure: Regular monitoring and management.
2. Avoid Head Trauma: Wear helmets during risky activities.
3. Limit Alcohol Intake: Excessive drinking can raise blood pressure.
4. Manage Stress: Techniques like yoga or meditation.
5. Healthy Diet: Low in saturated fats and high in fruits and vegetables.
6. Regular Exercise: Maintain cardiovascular health.
7. Quit Smoking: Smoking damages blood vessels.
8. Use Seat Belts: Prevents injury during car accidents.
9. Monitor Medications: Discuss risks of anticoagulants with a doctor.
10. Genetic Counseling: If there’s a family history of aneurysms or vascular diseases.

When to See a Doctor for Convexal Subarachnoid Hemorrhage

Seek medical attention immediately if you experience:

• Sudden, severe headache
• Loss of consciousness or confusion
• Weakness or numbness
• Difficulty speaking or understanding speech
• Seizures
• Nausea and vomiting
• Blurred or double vision
• Stiff neck

Conclusion

Convexal subarachnoid hemorrhage (cSAH) is a serious condition that requires prompt medical attention and appropriate treatment based on the underlying cause. By understanding the symptoms, causes, diagnostic methods, and treatment options, individuals can better recognize and manage this condition. Early intervention and preventive measures play a crucial role in improving outcomes and reducing complications associated with cSAH.
