Improving Outcomes for Lower Extremity Amputations Using Intraoperative Fluorescent Angiography to Predict Flap Viability

Abstract

IFA during LEA is safe and easily performed by the vascular surgeon. The RPVs as a predictor of skin flap viability correlate well with those reported in breast reconstructive surgery. Unfortunately, APVs fail to support any predication for flap failure or success. Patient comorbidities and intraoperative variables such as vasopressor use may contribute to this finding.
