title: Pedicled flaps for lower extremity reconstruction in the elderly: a retrospective study of 16 cases.
abstract: We reviewed a consecutive series of 16 patients above 60 years of age (mean age 71 years) who underwent reconstruction with pedicled flaps in the lower extremity. The soft tissue defects ranged from 9 to 50 cm and were caused in 11 patients (70%) by surgical complications from previous surgeries. Of these, 5 patients underwent a total joint replacement of the knee (4 cases) and of the ankle (1 case). Surgery consisted of 19 muscular flaps, and 3 fasciocutaneous flaps. Six patients were treated with a combination of 2 flaps. The overall surgical complication rate after reconstruction was 44%. There was no perioperative mortality and there were no medical complications. One patient required an above-the-knee amputation because of uncontrollable postoperative bleeding. A thrombectomy was performed in another patient to treat a postoperative popliteal artery occlusion with critical ischemia of the leg. Other complications included recurrent total joint replacement infections (2 cases), marginal flap necrosis (4 cases), and skin necrosis at the donor site (1 case). The mean hospitalization stay was 46 days. All patients but 1 completely healed, although secondary surgery was performed in 7 patients. The occurrence of complications was not correlated with the preoperative morbidity or an age above 75 years. The local complication rate was higher than reported for free flap in the same age category, but the lack of perioperative mortality and medical complications make it a low-risk option for reconstruction of small- to middle-sized defects in the elderly.
