Abstract

  This study was designed to introduce the cross-leg free flap only for vein anastomosis as an alternative salvage method for the reconstruction of severe soft tissue defects in vascular-compromised lower extremities. Four cross-leg free flap reconstructions were performed using the latissimus dorsi muscle to reconstruct soft tissue defects in the lower extremity. The recipient artery was confined to the ipsilateral side and the venous anastomosis was carried out in the contralateral side. Both legs were immobilized together with an external fixator. All patients were males, and had a mean age of 31 years. The mean time of pedicle division was 8.8 days range of 7 to 10 days. The mean size of the flap was 186.5 cm2. All flaps survived after pedicle division without venous congestion. There was no complication in joint stiffness, nor donor site morbidity except for a linear scar. The cross-leg free flap only for vein anastomosis is a refinement of a salvage procedure used for the reconstruction of severe soft tissue defects in vascular-compromised lower extremities.

Key Words: Cross-leg free flap, Lower extremity reconstruction, Vein repair.
