外科手术治疗小脑后下动脉瘤临床分析

Clinical Analysis of Surgery for Posterior Inferior Cerebellar Artery Aneurysm

目的探讨小脑后下动脉瘤的影像学特征及外科治疗方案。方法回顾性分析3例小脑后下动脉瘤的临床特点、影像学特征及手术治疗效果。结果 3例CT检查均有第四脑室出血;三维CT血管造影(3DCTA)检查可显示动脉瘤的具体部位及大小。3例均后颅窝开颅显微手术治疗,夹闭动脉瘤蒂。术后全部恢复良好。结论小脑后下动脉瘤多以第四脑室出血发病,及早诊断和治疗,显微手术夹闭动脉瘤蒂,取得了满意的疗效。

[Objective]To explore the imaging characteristics and surgical approach of posterior inferior cerebellar artery aneurysm.[Methods]The clinical features,imaging characteristics and surgical results of three cases of posterior inferior cerebellar artery aneurysm were analyzed retrospectively.[Results]The fourth ventricle hemorrhage was detected in 3 cases by CT examination,and three-dimensional CT angiography （3DCTA） can show the specific location and size of aneurysm.3 cases were treated by posterior fossa microsurgical craniotomy,and pedicle aneurysm was clamped.All cases recovered well after surgery.[Conclusion]Most of patients with posterior inferior cerebellar artery aneurysm were found with fourth ventricle hemorrhage.With early diagnosis and treatment,pedicle aneurysm was clamped by microsurgical craniotomy,the efficacy was satisfactory.
