Angiographic Findings of Vertebral Dissecting Aneurysm

Spontaneous Dissecting Aneurysm of the Intracranial Vertebral Artery: Management Strategies

PURPOSE Pathogenesis and treatment of spontaneous dissecting aneurysm of the intracranial vertebral artery (VA) remain controversial. This study was designed to provide management strategies and to improve management outcome in patients with these aneurysms. MATERIALS AND METHODS Among a total of 1,990 patients treated for intracranial aneurysms from February 1992 to June 2005, 28 patients (1...

Vertebral artery dissecting aneurysm rebleeding after proximal occlusion--case report.

A 38-year-old male presented with vertebral artery dissecting aneurysm manifesting as subarachnoid hemorrhage. An attempt at trapping the aneurysm failed, so the vertebral artery could only be clipped proximally. Rebleeding occurred, resulting in death, probably due to excessive length of the dissection requiring thrombosis and/or retrograde dissection due to back pressure from the contralatera...

Ruptured vertebral artery dissecting aneurysm associated with parent artery occlusion.

A 63-year-old hypertensive man presented with vertebral artery (VA) dissection manifesting as subarachnoid hemorrhage located mainly in the posterior fossa. Left vertebral angiography on the day of hemorrhage showed complete occlusion of the left VA. Right vertebral angiography showed retrograde filling of the distal portion of the left VA and the left posterior inferior cerebellar artery, and ...

Rebleeding from intracranial dissecting aneurysm in the vertebral artery.

We describe two patients with rebleeding from intracranial vertebral artery dissecting aneurysms during the acute stage. One patient had excellent results after emergency surgery. A review of recent reports including 60 patients with this disorder revealed a rebleeding rate of 30%, mostly during the acute stage. This suggests that a ruptured dissecting aneurysm in the vertebral artery is at ris...
