FIG 1. A, Anteroposterior (AP) view of stenotic middle cerebral artery (curved arrow). Note significant attenuation of distal portion of vessel (arrowheads). Most proximal portion of vessel shows ulcerated plaque, almost giving the appearance of an aneurysmal dilatation.
B and C, AP view of vessel during (B) and after (C) balloon angioplasty. Note improved patency but significant irregularity with recoil of lumen (curved arrow, B) after the procedure. The ulcerative character of plaque is better displayed in this view.
D–F, AP view of coronary stent prior (D), during (E), and after (F) deployment in the middle cerebral artery. Note smooth appearance of the lumen, with obliteration of the plaque ulcer at the end of deployment.
