Endovascular Embolization of Multiple Intracranial Aneurysms

Objective To explore the safety and efficacy of endovascular treatment of multiple intracranial aneurysms (MIA). Methods The clinical and imaging data of 16 patients with MIA who underwent endovascular embolization were analyzed retrospectively. Of 38 intracranial aneurysms in the 16 patients, 36 were in the anterior circulation, 2 were in the posterior circulation. The disease conditions in 5 patients belonged in Hunt-Hess grade Ⅰ, in 6 patients in grade Ⅱ, in 3 patients in grade Ⅲ and in 2 patients in grade Ⅳ. Results A total of 37 aneurysms in 16 patients were successfully embolized. In 1 patient with 2 aneurysms, only the aneurysm which produced subarachnoid hemorrhage was embolized and the other aneurysm was clipped by craniotomy. Of 16 patients, 11 were recovered well, 3 moderately disabled, 1 severely disabled, and 1 vegetably survived according to GOS. There was no rebleeding in all the patients during follow-up for over 6 months. Conclusions The endovascular embolization is a safe and effective method to treat MIA. The ruptured aneurysm should be treated by surgery as soon as possible, but the unruptured aneurysms should be selectively treated according to Guidelines for the surgical treatment of unruptured intracranial aneurysms.
