Use of Indocyanine Green as a Mark for Intersegmental Plane During Thoracoscopic Segmentectomies: An Apparent Failure

The use of near-infrared imaging after systemic injection of indocyanine green (ICG) is becoming the method of choice for marking the intersegmental plane during video-assisted segmentectomies. The authors present a short video showing a suspected failure of ICG during a thoracoscopic basilar segmentectomy. A thorough examination of the three-dimensional modelization demonstrated that this was not a failure of the ICG but rather an anatomic variation that had not been previously appreciated.
