Types of Emboligenic Posterior Cerebral Artery Strokes:

  1. Ischemic Stroke: PCA strokes typically fall under this category, which occurs when a blood clot obstructs a blood vessel in the posterior cerebral artery, reducing blood flow to the brain.

Common Causes of Emboligenic Posterior Cerebral Artery Strokes:

  1. Atrial Fibrillation: Irregular heart rhythm can lead to blood clots forming in the heart, which can then travel to the brain, causing a stroke.
  2. Carotid Artery Disease: The narrowing or blockage of the carotid arteries can lead to reduced blood flow to the PCA.
  3. Heart Valve Abnormalities: Conditions like mitral valve stenosis or prosthetic heart valves can increase the risk of blood clots forming.
  4. Hypertension: High blood pressure can weaken blood vessels and increase the likelihood of clots forming.
