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.

Double Origin

Background Double origin of the posterior inferior cerebellar artery (DOPICA) has been rarely reported in the literature, with a reported incidence of 1.45%. In contrast, a high concurrence rate of DOPICA and vertebral artery dissecting aneurysm has been reported. Clinical presentation A 61-year old woman presented with vomiting and diplopia with preceding headache. Magnetic resonance imaging (MRI) showed fresh infarction of the left lateral medulla and a vertebral artery dissecting aneurysm of the left vertebral artery. The next day, she exhibited transient loss of consciousness and worsening of headache, and MRI depicted subarachnoid hemorrhage. Four-vessel digital subtraction angiography showed a posterior inferior cerebellar artery (PICA) arising both intracranially and extracranially from the left vertebral artery. Although the dissecting lesion involved the V3 and V4 portion, it did not involve an extracranially originating PICA. Internal trapping of the V3 and V4 portion was chosen as the extracranial channel was expected to supply the PICA territory. This procedure was safely performed. Conclusion Early endovascular intervention should be considered in the treatment of dissecting aneurysm of vertebral artery associated with DOPICA for patients with relatively long lesions even in unruptured cases.
