Vein grafts in reconstructive microsurgery of the lower extremity.
This paper describes surgical techniques and results of lower extremity microsurgical reconstruction using vein grafts. During a 5 year period, free tissue transfers were used to reconstruct 118 lower extremity defects in 109 patients. In 28 of these cases (24%), saphenous vein grafts were used when reconstruction would otherwise have been difficult or impossible. A preliminary arteriovenous fistula was established between the proximal arterial source and the final venous drainage in the majority (26) of cases. Venous drainage was left intact at the point of entry into the deep venous system in 23 cases. Three complications included anastomotic clotting in 2 patients and postoperative blow-out of the vein graft in another; all were treated without flap loss. Flap survival was 86% in vein grafted patients and 94% in those cases in which vein grafts were not used. Flap loss was related in each case to the nature of the pre-existing condition, rather than to vein grafting per se.
