Endovascular therapy of posterior circulation aneurysms

Abstract

Objective To investigate the safety and feasibility of endovascular therapy in posterior circulation aneurysms. Method There were 47 patients with posterior circulation aneurysms in this group, 25 aneurysms located in the apex of basilar artery,4 aneurysms in superior cerebellar artery,5 aneurysms in posterior inferior cerebellar artery,2 aneurysms in anterior inferior cerebellar artery,9 dissect aneurysms in vertebral artery,other 2 patients suffered from multiple aneurysms. 23 patients were treated with coiling, 16 patients with balloon assisted coiling, 7 patients with Neuroform stent assisted coiling, 1 patient was with Neuroform stent. Results 37 patients received complete occlusion,9 patients received 95% occlusion. 1 patient combined with Moyamoya disease died of widespread brain swelling and cerebral hernia after the procedure. There was no SAH within follow-up period. DSA was performed in 5 patients, there was no recurrence. The patient solo-treated with stent was followed up with DSA one month later,and the aneurysm disappeared. Conclusions Endovascular therapy is a valuable and safe method for treatment of posterior circulation aneurysms, balloon remodeling and stent assistant embolization should be performed in wide-necked aneurysms.
