血管搭桥术在复杂前循环动脉瘤中的应用

Bypass for complex anterior circulation aneurysms

大部分前循环动脉瘤可通过开颅动脉瘤夹闭术或血管内介入动脉瘤栓塞术治疗,但仍有少部分复杂动脉瘤,无论是开颅夹闭还是介入栓塞均难以保证载瘤动脉或分支通畅,需行血管搭桥术。本文对复杂前循环动脉瘤血管搭桥术指征、种类及其在前循环各部位动脉瘤中的应用和术后并发症等进行简要概述。

Because of the anatomical characteristics and the complexity of procedures,the treatment of complex anterior circulation aneurysms is a real challenge.Direct surgery,whether by interventional neuroradiology or microsurgical clipping,are not always applicable.In patients that would not tolerate parent or collateral artery sacrification,the adjunction of revascularization procedure by using bypass technique might be necessary.In this article,the authors introduce different aspects in the management of patients with a complex anterior circulation aneurysm using bypass,the indications and types of bypass,surgical techniques and complications.
