Abstract：Objective To investigate the safety and efficacy of endovascular treatment of posterior inferior cerebellar artery bulbar segment aneurysms.Methods The clinical data,imaging features and endovascular treatment plan of 9 patients with posterior inferior cerebellar artery bulbar aneurysm treated with endovascular treatment were retrospectively analyzed from January 2014 to April 2024 in the Department of Neurosurgery of the First Affiliated Hospital of Soochow University.The posterior inferior cerebellar artery bulbar segment aneurysms were confirmed by CTA or cerebrovascular angiography in all patients,and endovascular treatment was performed in all patients,including 3 cases with simple spring coil embolization,2 cases with stent-assisted spring coil embolization,1 case with simple stent implantation,and 3 cases with occlusion of the aneurysm and carrier artery.Results Among the 9 patients,there were 2 unruptured aneurysms,There were 7 cases of ruptured aneurysm,and the HuntHess grade was as follows:2 cases of grade 0,2 cases of grade I,2 cases of grade II,1 case of grade III,and 2 cases of grade IV.One patient developed central alveolar hypoventilation syndrome,one died of pulmonary infection,and one was complicated by Hornor's,syndrome.Conclusion Endovascular treatment is a feasible,safe and effective treatment for posterior inferior cerebellar artery bulbar segment aneurysm.
