The use of near-infrared spectroscopy (NIRS) in surgical clipping of giant cerebral aneurysm

Discussion Intraoperative cerebral ischaemic complications may be due to improper temporary or permanent clip application, prolonged temporary clipping time, retraction injury and cerebral vasospasm. With respect to intraoperative neuromonitoring, in addition to EEG, NIRS was used to monitor cerebral oxygen saturation during periods of potentially compromised cerebral blood flow (in this case, prolonged temporary parent artery occlusion of 67 min).
