Subarachnoid Hemorrhagic Posterior Choroidal Artery Stroke

Subarachnoid Hemorrhagic Posterior Choroidal Artery Stroke, or simply SAH-PCA stroke, is a medical condition that affects the brain. In this article, we’ll break down the key aspects of this condition in plain English, making it easy to understand for everyone.

Types:

There is one primary type of SAH-PCA stroke, which occurs when there is bleeding in the brain’s subarachnoid space due to the rupture of blood vessels near the posterior choroidal artery. This type is often called an aneurysmal subarachnoid hemorrhage.

Causes 

  1. Aneurysm rupture: The most common cause, where a weak spot in a brain artery bursts.
  2. High blood pressure: Puts extra strain on blood vessels.
  3. Head injury: Can damage blood vessels and lead to bleeding.
  4. Smoking: Increases the risk of blood vessel problems.
  5. Family history: A genetic predisposition to aneurysms.
  6. Alcohol abuse: Weakens blood vessels.
  7. Cocaine or amphetamine use: Raises blood pressure and stroke risk.
  8. Brain tumors: Can cause pressure on blood vessels.
  9. Infections: Like meningitis, that affect the brain’s blood vessels.
  10. Polycystic kidney disease: Increases aneurysm risk.
  11. Arteriovenous malformations (AVMs): Abnormal connections between arteries and veins.
  12. Age: Risk increases with age.
  13. Gender: More common in women.
  14. Race: More common in African Americans.
  15. Hormonal changes: Linked to aneurysm formation.
  16. Excessive caffeine intake: Can raise blood pressure.
  17. Birth control pills: May increase the risk in some women.
  18. Use of blood thinners: Increases the risk of bleeding.
  19. Obesity: Linked to higher blood pressure.
  20. Uncontrolled diabetes: Can damage blood vessels.

Symptoms 

  1. Sudden severe headache: Often described as the “worst headache of my life.”
  2. Nausea and vomiting: Due to increased pressure in the brain.
  3. Stiff neck: Difficulty moving the neck without pain.

  13. Loss of consciousness: Fainting or passing out.
  14. Difficulty swallowing: Problems eating or drinking.
  15. Changes in personality or mood: Sudden shifts in behavior.
  16. Ringing in the ears (tinnitus): Hearing unusual sounds.
  17. Hallucinations: Seeing or hearing things that aren’t there.
  18. Facial pain: Pain on one side of the face.
  19. Dizziness: Feeling lightheaded or unsteady.
  20. Coma: A deep state of unconsciousness.

  6. Transcranial Doppler ultrasound: Measures blood flow in the brain.
  7. EEG (Electroencephalogram): Records brain’s electrical activity.
  8. Blood tests: Check for infection and assess overall health.
  9. X-rays: Can reveal skull fractures or bone issues.
  10. Glasgow Coma Scale: Measures consciousness level.
  11. Mini-Mental State Examination (MMSE): Evaluates cognitive function.
  12. Vision and hearing tests: Assess sensory functions.
  13. Carotid ultrasound: Examines neck arteries for blockages.
  14. Echocardiogram: Looks at the heart for possible blood clot sources.
  15. Genetic testing: Identifies hereditary factors.
  16. Blood pressure monitoring: To manage hypertension.
  17. PET scan: Measures brain activity and blood flow.
  18. Neuropsychological tests: Assess cognitive and emotional changes.
  19. Evoked potentials: Measure brain’s response to stimuli.
  20. Arterial blood gas analysis: Checks oxygen and carbon dioxide levels in blood.

Treatments 

  1. Aneurysm clipping: Surgical placement of a metal clip to stop bleeding.
