Reconstruction of the Lower Abdominal Region Using Bilateral Pedicled Anterolateral Thigh Flaps Combined With Poly-Surgical Mesh: A Case Report

The en-bloc resection of neoplasms on the abdominal wall often causes extensive defects that are difficult to manage. The anterolateral thigh (ALT) flap is a widely used flap in reconstructive surgery of defects. In this article, we present a case using bilateral pedicle anterolateral thigh flaps combined with a surgical polymesh to repair a large defect (22 cm × 18 cm) caused by dissection of a recurrent fibromatosis with good functional and aesthetic effects. There were no obvious morbidities or complications during a 6-month follow-up period. We conclude that the bilateral pedicle anterolateral thigh flap is a good choice for reconstruction of large lower abdominal wall defects. It can afford sufficient soft tissue coverage without obvious donor site morbidity.
