A Systematic Review On the Anatomy of the Descending Branch of the Lateral Circumflex Femoral Artery and The Vascularization of Fascia Lata and Its Implication for The Upper Abdominal Wall Reconstruction with Pedicle Fascia Lata Flap: Our Case Series

defects due to trauma, hernias, infections, radiation necrosis, decompressive laparotomy, or tumor resection is challenging. There is no single best method for repair; choices depend on the defect's size, location, tissue viability, and contamination level. Abdominal defects are classified into Type I (intact/stable skin cover) and Type II (unstable/absent skin cover) defects, with Type II further divided into zones 1A, 1B, 2, and 3 as described by Mathes et al. classification [1]. Component separation and the use of autologous material and prosthetic material insertion methods can be used to manage Type I defects and small Type II defects [2].Large, contaminated defects are particularly difficult to manage due to the contraindication of synthetic materials. Effective repair involves tension-free restoration of the abdominal wall, often using autologous tissues. The thigh, with its reliable vascular supply and strong fascial layer, is a valuable donor site to reconstruct the abdominal defects but supraumbilical defects were previously thought unreachable by a pedicle flap from the thigh [3]. Flaps from this area, such as the Tensor Fascia Lata (TFL) and the anterolateral thigh (ALT) flaps, are commonly used. The TFL flap, though effective, has limitations like short pedicle length and donor site complications
