Posterior Circulation Thrombosis

Posterior circulation thrombosis occurs when a blood clot forms in the arteries supplying blood to the back part of the brain, including the brainstem, cerebellum, and occipital lobes. This condition can lead to a stroke, causing significant neurological problems due to disrupted blood flow.

Types

1. Embolic Stroke: A clot that travels from another part of the body to the brain.
2. Thrombotic Stroke: A clot that forms directly within the arteries of the brain.
3. Lacunar Stroke: Small clots that block tiny arteries.
4. Watershed Stroke: Caused by decreased blood flow in areas of the brain located between major arteries.
5. Transient Ischemic Attack (TIA): A temporary clot that resolves on its own but can be a warning sign for a future stroke.
6. Hemorrhagic Stroke: Bleeding in the brain due to ruptured blood vessels, though not a direct type of thrombosis, can be related to clotting disorders.
7. Cerebral Venous Thrombosis: Clot formation in the veins of the brain.
8. Basilar Artery Thrombosis: Clot in the main artery supplying the brainstem.
9. Posterior Cerebral Artery Thrombosis: Clot in the artery supplying the occipital lobes.
10. Vertebral Artery Thrombosis: Clot in one of the arteries supplying the posterior part of the brain.
