小脑后下动脉远端动脉瘤的临床治疗

目的 总结小脑后下动脉( PICA)远端动脉瘤的临床特点,探讨其临床治疗方式的选择.方法 回顾性研究16例PICA远端动脉瘤的临床特点及治疗.6例行后正中入路开颅动脉瘤夹闭术；4例行枕下远外侧入路动脉瘤夹闭术；6例行血管内栓塞术.结果 术后15例恢复良好,1例死亡,1例合并交通性脑积水,行脑室-腹腔分流术.15例出院时均无神经系统阳性体征,随访患者恢复良好.结论 对于PICA远端动脉瘤的治疗,应根据患者的临床情况及动脉瘤和PICA的形态,可以选择开颅夹闭或血管内栓塞.

Clinical treatment of aneurysm of distal part of posterior inferior cerebellar artery

Objective To study the clinical features and surgical treatment of aneurysms of distal part of posterior inferior cerebellar artery (PICA).Methods The clinical features and treatment of sixteen cases with aneurysms of distal part of PICA within last 3 years were studied retrospectively.Six patients underwent clipping of aneurysm through the middle posterior approach,four underwent clipping through suboccipital lateral approach,and the other underwent endovascular embolization.Results The postoperative course of fifteen patients was uneventful and one patient dead from the respiratory and circulatory complications.Fifteen patients were discharged without neurological deficits and remained well in follow - up.Conclusions As for a given patient with aneurysms of distal part of PICA,whether surgical or endovascular treatment should be selected depending on the attitude of the neurosurgeon and the patient,especially the clinical condition of the patient and morphology of the artery and aneurysm.
