The Utility of Preoperative Venous Testing for Lower Extremity Flap Planning in Patients with Lower Extremity Wounds

摘要

Background: Although venous thrombosis is a leading cause of flap failure, the majority of lower extremity free flap planning is centered on arterial system evaluation. Preoperative identification of relevant abnormality in lower extremity venous systems by means of duplex ultrasound may aid in the diagnosis of clinically important abnormality that could affect lower extremity flap outcomes.
