Le lambeau de serratus anterior en chirurgie reconstructrice du membre inférieur. À propos de 30 cas

Abstract

Between 2001 and 2003, 30 serratus anterior free flaps have been realized in our unit for reconstruction of lower limb. The flaps were indicated for repair of traumatic soft tissue defect in 19 cases, for chronic wound in six cases, for purpura fulminans in two cases, for pressure sore in one case and after tumor resection in 1 case. There were 29 patients: 25 males and four females. They ranged in age from 5 to 64 years. The size of the soft tissue defects ranged between 15 and 180 cm 2. Four different types of serratus anterior flaps were used: 20 muscle flaps ; four myocutaneous flaps ; five costo-osteomuscular flap ; one costo-osteomyocutaneous flap . In all cases we used osteo flap (8 th rib) in order to restore bone defect, which ranged from 9 to 15 cm. Necrosis occurred in two flaps because of venous thrombosis. The functional outcome was good for all patients and the aesthetic sequelae at the donor site were considered as minor. The serratus anterior flap can be used in many different ways: different kinds of flaps (osteo-cutaneous-muscle); very variable size of flap (15 to 180 cm 2 in our series) , different length of pedicle possible. Because of his versatility and his absence of major functional or aesthetic sequelae the serratus anterior free flap has become day by day our favourite option in limb reconstruction.
