吲哚菁绿血管造影在颅内外搭桥手术中的应用

目的探讨吲哚菁绿（ICG）血管造影在颅内外血管搭桥术中判定吻合口通畅性方面的作用。方法回顾性分析2009年12月至2012年12月57例患者的临床资料，共行颅内外搭桥手术61例次，共68处吻合口。吻合术后均行ICG血管造影，观察搭桥血管通畅情况，并与术后1周内的数字减影血管造影（DSA）或CT血管造影（CTA）检查结果比较。结果术中ICG血管造影有良好的时间和空间分辨率，发现4处吻合口闭塞，给予重新吻合。最终造影显示67处通畅，1处闭塞。术后DSA和CTA检查示66处吻合口通畅，2处闭塞。结论术中ICG血管造影可以判断颅内外搭桥吻合口的通畅性，是一种简便、迅速、准确的术中血管造影技术。

Utility of intraoperative indocyanine green videoangiography in extracranial-intracranial bypass

Objective The aim of the study is to determine the efficacy of indocyanine green （ICG） videoangiography for confirmation of vascular anastomosis pateney in extracranial-intracranial bypasses. Methods The clinical data of 57 patients with 68 anastomosises, who underwent ICG angiography after the extracranial-intracranial bypass from December 2009 to December 2012, were retrospectively analyzed. After completion of the bypass, ICG was administered to assess the patency of the graft. The findings on ICG videoangiography were then compared to postoperative digital subtraction angiography （DSA） or CT angiography （CTA） within 1 week postoperatively. Results ICG provided an excellent visualization of all cerebral arteries and grafts at the time of surgery. Four grafts were determined to be occluded and were revised at the time of surgery. Findings on ICG videoangiography which showed 67 grafts patent correlated with postoperative imaging showing 66 anastomosises patent. Conclusion ICG videoangiography is rapid, effective, and reliable in determining the intraoperative patency of bypass grafts.
