Abstract
Introduction:
Wound complications within the immediate perioperative period for lower extremity amputation at any level ranges from 13 to 79%. More than half of readmissions following TMA, BKA and AKA, specifically, are due to wound related complications . Although multiple risk factors contribute to suture line complications a major factor is inadequate perfusion to the suture line. Fluorescence angiography allows for intraoperative assessment of suture line perfusion and facilitates intraoperative modifications to ensure adequate perfusion to the suture line exists prior to leaving the operating room.
Materials and Methods:
Fluorescence angiography was used in 27 cases (26 patients) requiring lower extremity amputation ranging from digital to above knee amputation to assess microperfusion of the flaps after creation and closure. Results of this imaging was used to guide the need for modification to ensure adequate perfusion to the amputation site prior to leaving the operating room.
