The reverse sural artery flap for the reconstruction of distal third of the leg and foot.
Soft tissue defects around the distal third of the leg and the foot present a major reconstructive challenge. There is limited expertise with free tissue transfers in many developing countries, necessitating consideration of other options for the closure of such defects. The versatility and reliability of sural artery flap have made it an emerging popular option for the reconstruction of such defects. Twenty patients comprising of 13 males and 7 females with soft tissue defects of the lower third of the leg and foot requiring soft tissue cover were treated between January 2006 and December 2010. The age range was 7-58 years with a mean age of 30 years. Nineteen (95%) of the defects were post-traumatic while one (5%) was post-infective. All the defects were covered with reversed sural artery flaps, which were raised on the posterior aspect of the junction of the upper and middle third of the leg. The smallest flap was 4 × 4 cm(2) while the largest measured 20 × 12 cm(2). The donor defect was closed directly in 7 (35%) patients, while split skin graft was applied in the remaining 13 (65%) patients. There was satisfactory flap healing in 17 patients (85%), while 3 patients (15%) had complete flap necrosis. Two of these patients had significant comorbidities of haemoglobinopathy and poorly controlled diabetes mellitus. Sural artery flap remains a viable option for the reconstruction of soft tissue defects of the distal third of the leg and foot. Caution should, however, be exercised in patients with some significant systemic diseases.
