Pedicled Anterolateral Thigh Flap

Abstract

Reconstruction of extensive oncosurgical defects of lower trunk, perineum and upper thigh, without the complexity of microsurgery, is a reconstructive challenge. Pedicled anterolateral thigh (ALT) flap offers many advantages over other regional flaps for this purpose, such as the large skin and soft tissue availability, the remarkable pedicle length and the reliability. However, there is paucity of literature describing the utility of pedicled ALT flaps for reconstruction of these difficult soft tissue defects. We present our experience of pedicled ALT flaps for various post oncosurgical defects. From January 2005 to August 2008, 85 pedicled ALT flaps were done in 78 patients for post oncological excision defects of lower trunk, groin, perineum, and upper thigh. Majority of patients were males, with locally advanced inguinal disease, underwent wide skin excision and en bloc nodal resection. Age group ranged from 22 to 81 years. The flap size ranged from 10 x 5 cm (50 cm) to 38 x 20 cm (760 cm). The length of the pedicle ranged from 8 to 14 cm. Satisfactory coverage was achieved in all patients, except one, where the flap had to be discarded due to absent artery in the vascular pedicle. Clinically, no functional deficit of knee extensor mechanism was seen in any of these patients during routine activities. Present study has shown the wide arc of rotation, large skin replacement potential, and reliability of pedicled ALT flap.
