Answer

Atherosclerotic basilar artery stenosis, like stenosis of any other intracranial artery, is more frequent in the African American and Asian populations than in white populations. The male-to-female ratio for basilar artery thrombosis is 2:1.

Basilar artery occlusion secondary to atherosclerosis is most prevalent in the sixth and seventh decades of life. Occlusion of the distal basilar artery is usually secondary to embolism and is most frequent in the fourth decade. Women with basilar artery occlusion are typically older than men.
