The Pedicled Anterolateral Thigh Flap as a Versatile Option for Resurfacing Extensive Lower Trunk Defects

Abstract

Background: The resurfacing of large abdominal and perineal defects is a major concern, and it poses a great challenge to the reconstructive surgeon. The main target in the reconstruction of the abdomen is to ensure a stable soft-tissue cover, and a strong and reliable fascia to prevent hernia recurrence and fecal contamination. The pedicled anterolateral thigh flap (ALT) either in the myocutaneous or fasciocutaneous form is a work-horse for the closure of abdominal and perineal defects. Aim: There is a paucity of studies on the use of the anterolateral thigh flap among black Africans especially in Nigeria; hence, we present our experience with the use of this flap for extensive abdominal and perineal defects. Patients and Methods: The folders of all patients who had pedicled anterolateral thigh flap between January 2019 and July 2022 in our institution were reviewed. The patients’ demographic data and the available details about the flap reconstruction were extracted from the folders. Results: There were three males and two females, and the age range was between 22 and 48 years. Four cases resulted from tumor extirpation, while one was following extensive necrotizing fasciitis of the lower anterior abdominal wall. No gross anatomical variations were encountered intraoperatively. Four flaps had full survival, while one had marginal flap tip loss. Conclusion: The pedicled anterolateral thigh flap is an excellent reconstructive tool for the coverage of extensive abdominal and perineal defects.
