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.

Use of indocyanine green videoangiography during intracranial aneurysm surgery reduces the incidence of postoperative ischaemic complications

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.     

Safety,efficacy, and cost of intraoperative indocyanine green angiography compared to intraoperative catheter angiography in cerebral aneurysm surgery

Intraoperative angiography in cerebrovascular neurosurgery can drive the repositioning or addition of aneurysm clips. Our institution has switched from a strategy of intraoperative digital subtraction angiography (DSA) universally, to a strategy of indocyanine green (ICG) videoangiography with DSA on an as-needed basis. We retrospectively evaluated whether the rates of perioperative stroke, unexpected postoperative aneurysm residual, or parent vessel stenosis differed in 100 patients from each era (2002, “DSA era”; 2007, “ICG era”). The clip repositioning rate for neck residual or parent vessel stenosis did not differ significantly between the two eras. There were no differences in the rate of perioperative stroke or rate of false-negative studies. The per-patient cost of intraoperative imaging within the DSA era was significantly higher than in the ICG era. The replacement of routine intraoperative DSA with ICG videoangiography and selective intraoperative DSA in cerebrovascular aneurysm surgery is safe and effective.     

Arteriovenous malformations and intraoperative indocyanine green videoangiography: preliminary experience

We report our preliminary clinical experience with microscope-integrated intraoperative indocyanine green (ICG) videoangiography in the treatment of arteriovenous malformations (AVMs). Nine patients underwent surgical procedures for AVMs. All patients had preoperative and early postoperative digital subtraction angiography (DSA). In all the procedures, ICG was injected intravenously during AVM occlusion and the removal of the nidus were directly analized into the microscope-integrated video, and they were compared with early postoperative angiography images. A total of 16 intraoperative ICG angiographies were performed. In all the patients the image quality was excellent, allowing intraoperative real-time evaluation of the completeness of the removal of the nidus. ICG videoangiography is easily performed during surgery for AVM and can confirm the completeness of the removal and may detect residual nidus, thus improving outcomes.
