Abstract: Objective To investigate the effect of intraoperative ICG angiography on surgery for hemorrhagic cerebral arteriovenous malformation（AVM）. Methods Eight patients with hemorrhagic AVM were underwent craniotomy in our hospital from January 2010 to December 2021.Intraoperative ICG fluorescence angiography, preoperative CTA and postoperative DSA vascular imaging data were retrospective analyzed in 8 patients. The role of ICG fluorescence angiography in operation was evaluated by comparing intraoperative ICG fluorescence angiography with preoperative CTA and postoperative DSA angiography. Results Of 8 cases, the AVM was clearly developed by intraoperative ICG angiography. The images of feeding arteries and draining veins were consistent with preoperative CTA images. No vascular malformation was found on ICG fluorescence angiography after operation, which was consistent with DSA vascular imaging. Conclusion Intraoperative ICG angiography can show the scope of AVM, and clarify the feeders and drainers, which has guiding significance in the resection of hemorrhagic AVM.

摘要： 目的 研究术中吲哚菁绿（ICG）荧光血管造影在出血性脑动静脉畸形切除术中的应用价值。方法 回顾性分析2010年1月至2021年12月我院收治的8例出血性脑动静脉畸形行开颅手术患者的术中ICG荧光造影、术前CTA及术后DSA血管影像资料。对比术中ICG荧光血管影像与术前CTA、术后DSA血管影像,评估ICG荧光血管造影在术中的作用。结果 8例患者血管畸形团在术中ICG荧光血管造影均显影清晰;供血动脉及引流静脉影像与术前CTA血管影像一致;切除术后ICG荧光血管造影血管畸形团均未显影,与术后DSA血管影像一致。结论 术中ICG荧光血管造影可以显示血管畸形团范围,明确供血动脉及引流静脉,在出血性脑动静脉畸形切除术中有指导意义。
