Posterior Cerebral Artery Infarct

A posterior cerebral artery (PCA) infarct, often referred to as a stroke, happens when blood flow to the posterior cerebral artery is blocked. This can lead to damage in the brain areas supplied by this artery. Understanding the types, causes, symptoms, diagnostic tests, treatments, and prevention of PCA infarcts can help in managing and preventing this condition.

Types of Posterior Cerebral Artery Infarct

1. Ischemic Stroke: Caused by a blockage in the artery.
2. Hemorrhagic Stroke: Occurs when an artery bursts and bleeds into the brain.
3. Embolic Stroke: A clot that travels from another part of the body to the brain.
4. Thrombotic Stroke: A clot forms directly in the brain artery.
5. Lacunar Stroke: Small vessel strokes deep within the brain.
6. Cardioembolic Stroke: Stroke due to clots from the heart.
7. Atherosclerotic Stroke: Stroke due to artery hardening and narrowing.
8. Transient Ischemic Attack (TIA): A temporary blockage that can be a warning sign for future strokes.
9. Watershed Stroke: Occurs in areas between major arteries.
10. Cryptogenic Stroke: A stroke with an unknown cause.
