Description
indocyanine green (ICG) as a tracer has recently been introduced as a novel technique for neurosurgery. We evaluated the feasibility and efficacy of near-infrared (NIR) indocyanine green (ICG) videoangiography for patients undergoing carotid endarterectomy (CEA). Methods Sixty patients (7 females, 53 males; mean age, 71.8 years) undergoing CEA for severe stenosis of the internal carotid artery (ICA) were included. During CEA, microscope-integrated intraoperative NIR videoangiographic recording was performed before and after the excision of the plaque and closure of the ICA. Results During the 60 CEA procedures, 60 consecutive ICG videoangiographic examinations were performed. All patients tolerated the intravenous injection of ICG well with no adverse effects. The videoangiographic study showed the blood stream of the ICA in all cases and the position of plaque in some cases. Conclusion Microscope-based ICG videoangiography is simple, and provides reliable and rapid intraoperative assessment of CEA.
