Which arteries are commonly considered large-vessel occlusions eligible for thrombectomy in acute stroke?

• A. Vertebral artery beyond V4.
• B. Anterior choroidal artery.
• C. Renal arteries.
• D. MCA M1/M2, intracranial internal carotid artery, basilar artery.

Answer: (D)

Mechanical thrombectomy is most effective for large-vessel occlusions in major intracranial arteries. The vessels that fit this category are the intracranial internal carotid artery, the trunk of the middle cerebral artery (MCA M1, and often M2 branches), and the basilar artery. Occlusions here block a large territory of brain tissue, leading to severe deficits, and these arteries are accessible with endovascular clot retrieval, with substantial evidence showing improved functional outcomes when treated promptly. Arteries outside this group aren’t typical targets for acute stroke thrombectomy. The vertebral artery beyond its skull entry point is outside the intracranial circulation typically treated in this context. The anterior choroidal artery is a smaller, deep penetrating branch, where thrombectomy isn’t standard. Renal arteries are not in the brain at all.
