BACKGROUND:: Recently, the non-invasive technique of microscope integrated intraoperative near infrared indocyanine green angiography [ICGA] was developed, allowing assessment of the cerebral vasculature in the operative field after intravenous injection of a fluorescent dye. OBJECTIVE:: To prospectively compare the value of ICGA derived information during cerebral aneurysm surgery with data simultaneously generated from other intraoperative monitoring and vascular imaging techniques. METHODS:: Data from 104 patients with 123 cerebral aneurysms operated on were prospectively recorded. Results of intraoperative vascular monitoring and descriptions of how this information influenced intraoperative decision-making were analysed. RESULTS:: Clip repositioning was necessary in 30 of 123 aneurysms [24.4 %] treated. Parent artery occlusion was documented by microvascular Doppler ultrasound in 4 aneurysms. ICGA disclosed parent artery stenoses that had escaped sonographic detection in 7 cases. Neuroendoscopy was used in 13 cases of midline aneurysms to confirm perforator patency after clipping and disclosed aneurysm misclipping undetected by ICGA and DSA in 1 aneurysm. The information from DSA and ICGA corresponded in 120 of 123 aneurysms operated [97.5 %]. In one patient, ICGA underestimated a relevant parent artery stenosis detected by DSA. In 2 patients with relevant aneurismal misclipping, DSA and ICGA led to conflicting results that could be clarified only when both methods were used and interpreted in conjunction. CONCLUSION:: The intraoperative monitoring and vascular imaging methods compared were complementary rather than competitive in nature. None of the devices used were absolutely reliable when used as a stand-alone method. Correct intraoperative assessment of aneurysm occlusion, perforating artery patency, and parent artery reconstruction was possible in all patients when these techniques were used in conjunction. |
