Stroke syndromes by vascular territory Flashcard Deck - 10 Cards

Flashcard 1: Which branch of the basilar artery arises just inferior to the posterior cerebral artery and supplies the superior surface of the cerebellum?

Answer: Superior cerebellar artery (SCA)

Flashcard 2: In the Circle of Willis, which vessel connects the two anterior cerebral arteries?

Answer: Anterior communicating artery (ACom)

Extra: The anterior communicating artery is the most common site for berry (saccular) aneurysms. Rupture leads to subarachnoid hemorrhage, while large aneurysms can compress the optic chiasm, leading to bitemporal hemianopsia.

Flashcard 3: Contralateral homonymous hemianopia with macular sparing is a visual deficit associated with _____ artery infarct

Answer: posterior cerebral

Flashcard 4: Which artery in the Circle of Willis supplies the medial aspect of the frontal and parietal lobes?

Answer: Anterior cerebral artery (ACA)

Flashcard 5: Saccular aneurysms of the _____ communicating artery may cause compression of the optic chiasm

Answer: anterior

Flashcard 6: What structure is most commonly compressed by an aneurysm of the anterior communicating artery?

Answer: Optic chiasm compression, resulting in bitemporal hemianopia.

Extra: Aneurysms of the anterior communicating artery (ACom) are the most common site of Berry aneurysms in the Circle of Willis. Due to their location, they can compress the optic chiasm, leading to visual field defects.

Flashcard 7: An aneurysm of which artery is most commonly associated with a CN III palsy?

Answer: CN III (Oculomotor nerve) palsy

Extra: Aneurysms of the posterior communicating artery (PCoA) typically cause a CN III palsy with pupil involvement (mydriasis), because the parasympathetic fibers are superficial on the nerve. Findings: Ptosis, "down and out" eye position, and a dilated pupil.

Flashcard 8: Where do saccular "berry" aneurysms tend to occur?

Answer: bifurcations in Circle of Willis; especially anterior and posterior communicating arteries

Flashcard 9: Identify the branch of the vertebral artery labeled as number 3 in the provided image.

Answer: posterior spinal arteries

Flashcard 10: Identify the artery in the vertebrobasilar system labeled as number 9 (the vessel formed by the union of branches from both vertebral arteries descending the spinal cord):

Answer: Anterior spinal artery

Extra: The anterior spinal artery is formed by the union of two small branches from the vertebral arteries. It descends in the anterior median fissure and supplies the anterior two-thirds of the spinal cord.
