OBJECTIVE
The aim of the study is to determine the efficacy of indocyanine green (ICG) videoangiography for confirmation of vascular anastomosis patency in both extracranial-intracranial and intracranial-intracranial bypasses.
METHODS
Intraoperative ICG videoangiography was used as a surgical adjunct for 56 bypasses in 47 patients to assay the patency of intracranial vascular anastomosis. These patients underwent a bypass for cerebral ischemia in 31 instances and as an adjunct to intracranial aneurysm surgery in 25. After completion of the bypass, ICG was administered to assess the patency of the graft. The findings on ICG videoangiography were then compared to intraoperative and/or postoperative imaging.
RESULTS
ICG provided an excellent visualization of all cerebral arteries and grafts at the time of surgery. Four grafts were determined to be suboptimal and were revised at the time of surgery. Findings on ICG videoangiography correlated with intraoperative and/or postoperative imaging.
CONCLUSION
ICG videoangiography is rapid, effective, and reliable in determining the intraoperative patency of bypass grafts. It provides intraoperative information allowing revision to reduce the incidence of technical errors that may lead to early graft thrombosis.
目的
本研究旨在确定吲哚菁绿（ICG）血管造影术在确认颅外-颅内和颅内-颅内旁路血管吻合通畅性方面的疗效。
方法
术中ICG血管造影术作为手术辅助手段，用于47例患者的56次旁路手术，以检测颅内血管吻合的通畅性。这些患者中，31例因脑缺血接受旁路手术，25例作为颅内动脉瘤手术的辅助手段。旁路手术完成后，注射ICG以评估移植物的通畅性。然后将ICG血管造影的结果与术中及/或术后影像学检查结果进行比较。
结果
ICG在手术时能很好地显示所有脑动脉和移植物。确定有4个移植物效果欠佳，并在手术时进行了修正。ICG血管造影的结果与术中及/或术后影像学检查结果相关。
结论
ICG血管造影术在确定旁路移植物术中通畅性方面快速、有效且可靠。它提供术中信息，允许进行修正以减少可能导致早期移植物血栓形成的技术失误发生率。
