Introduction The surgical clipping of ruptured posterior circulation aneurysms is usually challenging; therefore, endovascular embolization has been widely used for these aneurysms.
Aim of Study We aimed to describe the clinical outcome and angiographic results of various endovascular methods used for the management of ruptured posterior circulation aneurysms over the period of 2 years.
Methods A retrospective analysis was performed of 35 patients admitted with ruptured posterior circulation aneurysms who are treated with endovascular embolization. Various methods like coiling, stent assisted coiling, parent artery occlusion, flow diversion and neck bridging devices were used.
Results Out of 32 patients 5 are Hunt & Hess scale grade I, 8 in grade II, 9 in grade III, 5 in grade grade IV and 5 in grade V. The technical success rate of endovascular treatment was 93.75%, and the mean angiographic occlusion rate was 87.5%. At the latest clinical follow-up, 78.1% of patients achieved good recovery with Glassgow Outcome Scale (GOS) score of I. There was a significant correlation seen between the Hunt & Hess scale grade at presentation and the final GOS outcome score. Procedure related permanent morbidity was 15.6%, and repeated hemorrhage was observed in 2 patients.
Conclusion The study suggests the endovascular embolization is an effective method for the management of ruptured posterior circulation aneurysms, resulting in favorable outcomes and low permanent morbidity rates.
