Use of intraoperative indocyanine green angiography for detection and prediction of congestion in pedicled island flaps

Pedicled island flaps, including pedicled propeller flaps and pedicled transposition flaps, are widely used especially for coverage of soft tissue defects in the extremities and the trunk. However, due to its mobility limitations, the inset of the pedicled flaps can be challenging at times, especially when rotation or pressure is applied to the pedicle. The aim of this report is to evaluate the feasibility of intraoperative indocyanine green (ICG) angiography for detection and prediction of intraoperative and postoperative flap congestion in pedicled island flaps.
