The anatomy of the posterior communicating artery as a risk factor for ischemic cerebral infarction.
N Engl J Med. 1994; (22): 1565-70
After the occlusion of an internal carotid artery the principal source of collateral flow is through the arteries of the circle of Willis, but the size and patency of these arteries are quite variable. Study of the anatomy of the collateral pathways in patients with internal-carotid-artery occlusion with or without infarction in the watershed area of the deep white matter may identify patterns that afford protection from ischemic infarction.
