Dissecting Aneurysms

We report 17 patients with dissecting aneurysm of the vertebral artery (VA) who were treated by direct surgery (n=8) or interventional surgery (n=9). Eight patients presented with subarachnoid hemorrhage (SAH) and nine with ischemia. Ten patients were treated by trapping of the aneurysm that was occlusion of the VA on both sides of aneurysm (direct surgery, n=2; interventional surgery, n=8). The other seven patients were treated by ligation of the VA proximal to the aneurysm (direct surgery, n=6; interventional surgery, n=1). Two patients underwent transposition of the posterior inferior cerebellar artery (PICA). In 15 patients, there were no major complications. Two patients who had been treated by proximal occlusion of the VA developed rebleeding and ischemia due to persistent retrograde filling of the dissecting site. We suggest that angiographic evidence of retrograde filling of the dissecting site should have been considered as an indication for trapping. Trapping of VA dissecting aneurysms is easier and safer by interventional surgery than by direct surgery.
