This study was undertaken to demonstrate the usefulness of endovascular technique in treatment of vertebral artery dissecting aneurysms.
The clinical characteristics of vertebral artery dissecting aneurysms were reviewed in 11 patients with particular focus on clinical presentation, angiographic feature and outcome.
All patients underwent the GDC embolization. One of them was managed with surgical trapping after failure of GDC embolization and the other with GDC embolization after failure of stent insertion. Nine patients were recovered with intact neurological feature, one patient died as result of sepsis and ARDS, and one patient was suffered from cerebellar infarction.
Although the timing of the procedure and site of occlusion remain controversial, proximal GDC occlusion of vertebral artery appears to be a safe and effective therapy for patients with vertebral artery dissecting aneurysm. This procedure provides an important, less invasive alternative for this condition.
