title: Salvage of compromised free flaps in trauma cases with combined modalities.
abstract: Using the microsurgical technique for reconstruction in trauma cases represents a challenge for the reconstructive surgeon. Several methods of salvaging of a compromised free flap have been reported, among them: intravenous heparin washing, thrombolitic therapy, thrombectomy, use of grafts and others. Here, we present our experience from nine cases and a review of the literature regarding the use of various modalities for free flap salvage in trauma cases, and their results. Data was collected from trauma cases in our institutions over a period of 2 years, where reconstruction was performed using microsurgical techniques, and where subsequent complications required some type of salvage procedure. The techniques that were used for the salvage included: intravascular irrigation with heparin, papaverine and lidocaine; administration of continuous intravenous heparin, use of the Fogarty catheter, flap washing with streptokinase, and adventitia stripping. The free flaps used were latissimus dorsi, serratus anterior, and the anteromedial thigh flap. Either vein or artery thromboses were identified during the procedure or immediately after surgery in seven patients. Two patients had prolonged spasms of the recipient artery with low flow. In all cases, the No. 2 Fogarty catheter was used for thrombectomy and also for release of the vessel spasm. There was only one complete failure among these patients, and partial necrosis was encountered in three. From our experience and review of the literature, we offer an algorithm for determining treatment strategies in a range of flap salvage situations.
