在传统神经外科手术中,术前及术后需借助一系列血管检查,诸如CTA、MRA、DSA,获得血管信息,从而制定手术方案,判断手术效果。然而,术中动态获取实时脑血管解剖及血流动力学信息,根据术中情况及时调整手术方案,评估手术效果,仍较为困难。...在传统神经外科手术中,术前及术后需借助一系列血管检查,诸如CTA、MRA、DSA,获得血管信息,从而制定手术方案,判断手术效果。然而,术中动态获取实时脑血管解剖及血流动力学信息,根据术中情况及时调整手术方案,评估手术效果,仍较为困难。目前,术中获取血管情况的技术包括DSA、经颅多普勒超声(transcranial doppler,TCD)以及吲哚菁绿荧光造影(indocyanine green video angiography,ICGVA)等[1]。展开更多
