Posterior Cerebral Artery Strokes Induced by Fibrillation

Posterior Cerebral Artery (PCA) strokes can occur when there is a problem with the blood supply to the back of the brain. One of the common causes of PCA strokes is atrial fibrillation (AF), a heart condition where the heart beats irregularly. In this article, we will explain what PCA strokes are, the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgeries associated with them in simple, plain English.

Types of PCA Strokes

There are different types of PCA strokes, but we will focus on two main types:

  1. Ischemic PCA Stroke:
    • This occurs when a blood clot or plaque blocks the blood vessels that supply the PCA with oxygen-rich blood.
    • Think of it as a “traffic jam” in the blood vessels that prevents blood from reaching the back of the brain.
  2. Hemorrhagic PCA Stroke:
    • This type happens when a blood vessel in the PCA ruptures or leaks, causing bleeding in the brain.
    • Imagine a burst water pipe in your brain, causing damage due to the leaking blood.

Causes of PCA Strokes

Now, let’s explore some common causes of PCA strokes, with a focus on how AF can lead to them:

20 Causes of PCA Strokes:

  1. Atrial Fibrillation (AF): Irregular heart rhythm can create blood clots that travel to the PCA.
  2. Hypertension (High Blood Pressure): Increases the risk of vessel damage.
  3. Diabetes: Can lead to artery blockage over time.
  4. Smoking: Damages blood vessels and increases clotting risk.
  5. High Cholesterol: Deposits can narrow blood vessels.
  6. Obesity: Raises the chances of hypertension and diabetes.
  7. Family History: Genetics can play a role.
  8. Age: Risk increases with age.
  9. Sedentary Lifestyle: Lack of exercise can contribute.
  10. Excessive Alcohol Consumption: Can raise blood pressure.
  11. Drug Abuse: Certain drugs may lead to strokes.
  12. Heart Disease: Can result in blood clots.
  13. Migraines: Some types may increase stroke risk.
  14. Blood Disorders: Conditions like sickle cell disease.
  15. Sleep Apnea: Interrupted breathing affects oxygen supply.
  16. Carotid Artery Disease: Can cause blockages.
  17. Previous Strokes: Increases the likelihood of future ones.
  18. Mini-strokes (TIA): Warning signs of a potential PCA stroke.
  19. Infections: Some infections can affect blood vessels.
  20. Clotting Disorders: Abnormalities in blood clotting.

  15. Electroencephalogram (EEG): Records brain activity.
  16. Mini-Mental State Examination (MMSE): Evaluates cognitive function.
  17. Glasgow Coma Scale: Assesses consciousness.
  18. Visual Field Testing: Checks peripheral vision.
  19. Neurological Examination: Assesses motor skills and reflexes.
