Subarachnoid hemorrhage with blister aneurysms: Endovascular management

Abstract

Endovascular management using single/overlapping stent and if possible coil placement is technically safe and feasible in blister aneurysms. Overlapping stents lead to better aneurysm occlusion than a single stent. Blister aneurysm in dorso-medial ICA showed higher tendency of continued growth/recurrence, higher incidence of clinical vasospasm and in these cases early angiographic follow-up is advisable. Repeat treatment should be considered promptly if necessary.
