Bilateral Vertebral Artery Dissection: A Case Report with Literature Review

Figure 4

Cerebral angiography shows right vertebral artery dissection right past the C3 level at which a small pseudoaneurysm is noted in the artery anterior wall. This pseudoaneurysm tapers into the dissection which extends just beyond the C2 loop. There is marked reduction in luminal diameter and noticeable delay in antegrade flow distal to the dissection.
