吲哚菁绿术中血管造影在颅内动脉瘤的应用 总被引:1,自引:0,他引:1
吲哚菁绿血管造影是一种较新的评价脑血管内血流的术中监测手段,这一技术与手术显微镜整合后,可以提供术中动脉瘤、载瘤动脉以及周围相关动脉的实时血流信息,图像质量清晰,解析度高,可以有效地监测动脉瘤夹闭后是否残留、载瘤动脉是否狭窄及吻合血管、穿通血管是否通畅,对指导手术操作、提高手术质量和改善患者预后有着重要意义。同术中DSA、微血管多普勒超声及电生理检测等传统监测相比吲哚菁绿术中血管造影具有费用低廉,操作简便,耗时短,精确度高等明显优势,因此有可能在将来成为动脉瘤手术中的常规检查。 相似文献

目的 探讨吲哚菁绿荧光血管造影在颅内动脉瘤夹闭术中"假阴性"的原因及处理措施.方法 回顾分析2008年11月-2011年10月7例颅内动脉瘤夹闭术中吲哚菁绿荧光血管造影"阴性"患者手术治疗经过,分析术中吲哚菁绿荧光血管造影在显示动脉瘤夹闭完全性方面的局限性及应对原则.结果 7例患者均于术中吲哚菁绿荧光血管造影显示"阴性".但在剪开或刺破动脉瘤瘤体后出现少量渗血.经迅速清理瘤颈渗血并调整动脉瘤瘤夹位置,渗血消失.结论 吲哚菁绿荧光血管造影是术中监测动脉瘤是否夹闭完全的重要方法.但具有一定局限性,瘤颈较宽、瘤颈血栓形成或血管壁粥样硬化,以及蛛网膜分离不完全等情况均可能导致"假阴性"结果.因此,对于术中夹闭动脉瘤后吲哚菁绿荧光血管造影"阴性"的患者,仍需配合其他监测方法,进一步确认动脉瘤夹闭情况. 相似文献

Microscope-integrated near-infrared indocyanine green videoangiography (ICGVA) has been shown to be a useful adjunct for intracranial aneurysm surgery. That the routine application of this technique reduces the risk of postoperative ischaemic complication, however, has not been reported. We present a retrospective matched-pair comparison of ICGVA guided aneurysm surgery versus historic control surgical cohort treated by the same author. Index patients and controls were matched for aneurysm size, location, patient demographics, risk factors, comorbidities, and surgical treatments. Ninety-one eligible patients with 100 intracranial aneurysms were treated using ICGVA assistance. There were no statistically significant differences between the two groups in terms of patient age, sex, risk factors, comorbidities and aneurysm characteristics. Of the 100 aneurysms in the ICGVA group, 107 investigations of ICGVA were performed. In 79 aneurysms (79.0%), ICGVA was considered useful but did not affect surgical management. In six patients (6.0%), ICGVA led to a crucial change of intraoperative strategies. In nine patients (9.0%), it was considered critical in assuring patency of small perforators. ICGVA was of no benefit in four patients (4.0%) and was misleading in two (2.0%). Postoperative ischaemic complications occurred in three patients (3.3%) in the ICGVA group compared with seven patients (7.7%) in the control group (p < 0.001). Our study supports the use of ICGVA in aneurysm surgery as a safe and effective modality of intraoperative blood flow assessment. With all limitations of a retrospective matched-pair comparison, the use of ICGVA during routine aneurysm surgery reduces the incidence of postoperative ischaemic complications. 相似文献

目的 探引哚菁绿术中荧光造影术在脊髓硬脊膜动静脉瘘手术中的作用.方法 9例脊髓硬脊膜动静咏瘘患者,均经脊髓DSA确诊,行后正中全椎板切开,术中吲哚菁绿荧光造影明确供血动脉、引流静脉及瘘口,夹闭瘘口并选择性切除静脉血管畸形.结果 畸形血管位于颈段1例、胸段4例、胸腰段2例、腰段1例、胸腰骶段1例;介入栓塞不充分后转手术1例,介入栓塞微导管难以到位转手术8例;术后MRI显示髓周异常迂曲畸形血管消失,脊髓缺血水肿好转.术后症状消失2例,改善6例,无变化1例.结论 吲哚菁绿术中荧光造影能够明确供血动脉、引流静脉及瘘口情况,有效地提高了脊髓硬脊膜动静脉瘘手术的疗效.Abstract: Objective To evaluate the clinical significance of intraoperative indocyanine green (ICG)videoangiography in surgical management of spinal dural ateriovenots fistulae (dAVFs).Method In this retrospective analysis we examined nine cases of dAVFs, diagnosed by complete spinal angiography,in which laminoplasty were performed through posterior approach.An operating microscope - integrated light source containing infrared excitation light illuminated the operating field and was used to visualize an intravenous bolus of ICG.The locations of fistulae, feeding arteries and draininig veins were identified and compared before and after surgical obhteration by intraoperative ICG videoangiography.Results In the nine cases the dAVFs involved one cervical cord, four thoracic cord,two thoracic lumbar cord, one lumbar cord and one thoracic and lumbosacral cord.One of them used to take an unsuccessful endovascular embolization, while the rest of them were given the operation right after diagnosed by the spinal angiography.Microscope-based ICG videoangiography identified the fistulous point(s),feeding arteries and draining veins in all nine cases,as confirmed by postoperative MRI which showed complete obliteration of the dAVFs with improved spinal blood supply and reduced spinal cord edema.After the operation the clini cal symptoms were nearly disappered in two cases, improved in six cases, and present no obvious changes in one case.Conclusions Intraoerative ICG videoangiography provides real -time information about the precise location of spinal dAVFs,the feeding arteries and the draining veins, as well as additional feeding aiteries unrevealed by the preoperative spinal angiography and residue pathologic blood vessels during the operation, which efficiently improves the surgical outcomes and prognosis. 相似文献

Background
The goal of this report is to illustrate the use of intraoperative indocyanine green (ICG) angiography in the surgical management of intracranial aneurysms, including microsurgical clipping and revascularization.Methods
This study included a series of 45 patients who were surgically treated between June 2007 and May 2008 for intracranial aneurysms. Fourty-three of the patients had anterior circulation aneurysms, and 2 had posterior circulation aneurysms. Forty-one patients were treated with microsurgical clipping. Four patients underwent revascularization combined with aneurysm dissection or trapping. Intraoperative ICG angiography was used to visualize the aneurysm clipping, patency of parent artery or graft. The ICG angiography technique is described, with particular reference to evaluation of the aneurysm clipping and revascularization.Results
Eighty-nine ICG angiography procedures were performed in 45 patients with intracranial aneurysms. The aneurysms were completely obliterated for all patients, and the grafts were patented for all except 1 patient. Pre-clipping ICG angiography showed the relationship of aneurysm and its parent artery clearly. After aneurysms being clipped, intraoperative ICG angiography found remnant of aneurysms, stenosis or occlusion of parent arteries and grafts in 8 cases, which were revised in the same surgical procedure. The results of ICG angiography correlated well with postoperative DSA in 97% patients.Conclusion
ICG angiography can provide real-time information and guide revision in the same surgical procedure for the management of intracranial aneurysms. 相似文献16.
