title: Complications and vascular salvage of free-tissue transfers to the extremities.
abstract: Complications were examined in 122 free flaps to lower and upper extremities in 104 patients, and vascular salvage was examined in 182 free flaps to lower and upper extremities in 158 patients. All patients were treated by the same surgeon. The overall survival rate of flaps was 96 percent. Complications occurred in 22 percent of the flaps. Complication rates were lower in patients with one free flap than in patients with two. Flaps had more vascular complications than nonvascular. Accompanying skin islands were found to be necessary to monitor vascularized bone transfers in order to avoid flap failure. Flow in the pedicle was reestablished in all flaps, but a higher percentage of flaps with longer ischemic times were lost. Although vascular compromise occurred frequently (15 percent), prompt surgical exploration and reexploration were thought to have greatly increased free-flap survival.
