脑动脉瘤的血管内栓塞治疗

目的：探讨脑动脉瘤的血管内栓塞治疗。材料与方法：经股动脉或患侧颈动脉入路，对36例不同部位和形状的脑动脉瘤选用相适合的可脱乳胶球囊、游离微钨螺旋圈或机械性可脱钨螺旋圈进行载瘤动脉闭塞和瘤腔的严密填塞。结果：经脑血管造影证实，动脉瘤影像消失，仅有部分大型动脉瘤遗留少许残颈；随访中未发现蛛网膜下腔再出血。结论：脑动脉瘤的栓塞治疗是防止其破裂再出血的有效措施之一；对眼动脉段大型动脉瘤闭塞载瘤动脉前采用压颈造影是证实Willi’s环完整性的可靠方法。

Embolizing Treatment of Cerebral Aneurysms (An Analysis of 36 Cases)

Purpose: To evaluate the efficiency of embolizating therapy of cerebral aneurysms. Material and Method: All 36 aneurysmswere embolized with detachable balloons, free tungsten coils and mechanical detachable spirals (MDS) for occlusing parent artery or embolizing saccular aneurysms closely rely on deferent location and shape of aneurysms. Results: Disapeared aneurysms were shown by cerebraangiography after embolization but a little neck of some giant aneurysms remained. No rebleed was found during the following period from6 months to 3 years. Conclusion: Embolizing therapy of aneurysms is one of effective means for preventing break and bleed of aneurysms,It is a reliable method to confirm the integrate of Willi's circle that pressing carotid artery was used before occlusive parent artery of giant aneurysms located at segment of ophthalmic artery.
