intraoperative indocyanine green angiography for obliteration of a spinal dural arteriovenous fistula case report
Journal of Neurosurgery, 2009Co-Authors: Geoffrey P Colby, Philippe Gailloud, Alexander L Coon, Daniel M Sciubba, Ali Bydon, Rafael J TamargoAbstract:Spinal dural arteriovenous fistulas (DAVFs) are the most common type of spinal arteriovenous malformation and are an important, underdiagnosed cause of progressive myelopathy and morbidity in patients with spine disorders. Successful microsurgical management of these lesions is dependent on the surgeon's ability to identify vessels of the fistula and to confirm its successful obliteration postintervention. Indocyanine green (ICG) fluorescent angiography is an emerging tool for delineating intraoperative Vascular anatomy, and it has significant potential utility in the treatment of Vascular disease in the spine. The authors present the case of a 76-year-old man with progressive and debilitating bilateral lower-extremity weakness and numbness on exertion, in whom a left T-8 spinal DAVF was diagnosed based on results of conventional spinal angiography. Unfavorable anatomy based on angiographic findings precluded endoVascular embolization of the fistula, and the patient subsequently underwent T7-9 bilateral laminectomies for microsurgical clip occlusion. Intraoperative ICG fluorescent angiography was used before clip placement to identify the arterialized veins of the fistula, and after clip placement to confirm obliteration of the fistulous connection and restoration of normal blood flow. Intraoperative ICG angiography serves an important role in the microsurgical treatment of DAVF. It can be used to map the anatomy of the fistula in real time during surgery and to verify fistula obliteration rapidly after clip placement. This report adds to the growing body of literature demonstrating the importance of ICG angiography in Vascular Neurosurgery of the spine.

genealogy of training in Vascular Neurosurgery
Neurosurgery, 2014Co-Authors: Shakeel A Chowdhry, Robert F SpetzlerAbstract:Remarkable advances and changes in the landscape of neuroVascular disease have occurred recently. Concurrently, a paradigm shift in training and resident education is underway. This crossroad of unique opportunities and pressures necessitates creative change in the training of future Vascular neurosurgeons to allow incorporation of surgical advances, new technology, and supplementary treatment modalities in a setting of reduced work hours and increased public scrutiny. This article discusses the changing landscape in neuroVascular disease treatment, followed by the recent changes in resident training, and concludes with our view of the future of training in Vascular Neurosurgery.

prospective evaluation of surgical microscope integrated intraoperative near infrared indocyanine green angiography during cerebral arteriovenous malformation surgery
Neurosurgery, 2009Co-Authors: Brendan D Killory, Peter Nakaji, Fernando L Gonzales, Francisco A Ponce, Scott D Wait, Robert F SpetzlerAbstract:Objective Microscope-integrated indocyanine green (ICG) fluorescence angiography is a novel technique in Vascular Neurosurgery with potential utility in treating arteriovenous malformations (AVMs). Methods We analyzed the application of intraoperative ICG in 10 consecutive AVM surgeries for which surgical video was available. The ability to distinguish AVM vessels (draining veins, feeding and nidal arteries) from each other and from normal vessel was evaluated, and ICG angiographic findings were correlated with intra- and postoperative findings on digital subtraction angiography (DSA). Results ICG angiography was found to be useful by the surgeon in 9 of 10 patients. In 8 patients, it helped to distinguish AVM vessels. In 3 of 4 patients undergoing a postresection injection, it demonstrated that there was no residual arteriovenous shunting. In 1 patient, it helped to identify a small AVM nidus that was otherwise inapparent within a hematoma. Intraoperative DSA showed residual AVM in 2 of 10 patients requiring further resection of AVM not visualized during surgery. Conclusion Microscope-integrated ICG angiography is a useful tool in AVM surgery. It can be used to distinguish AVM vessels from normal vessels and arteries from veins based on the timing of fluorescence with the dye. Our experience suggests that it is less useful with deep-seated lesions or when AVM vessels are not on the surface. ICG angiography complements rather than replaces DSA.
