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.

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.
