Abstract:
OBJECTIVETo investigate the feasibility of free descending genicular artery perforator flaps in the soft tissue defects at extremities.
METHODSTen fresh cadavers were injected with lead oxide-gelatin mixture for three-dimensional visualization reconstruction using a 16-slice spiral computed tomography scanner and specialized volume-rendering software ( Materiaise's interactive medical image control system, MIMICS). The origin, course and distribution of the perforators in the thigh and leg region were observed. 11 patients with skin defects at the distal part of extremities were treated. The flap size ranged from 5 cm x 8 cm to 6 cm x 15 cm. Six flaps were pedicled with the descending genicular artery and the others were pedicled with the perforator of the descending genicular artery. All flaps were transferred by end to end anastomosis. RESULTS The follow-up period ranged from 6 to 18 months. All the flaps survived. The appearance and texture of the flaps were good with sensory recovery of S3.
CONCLUSIONSFree descending genicular artery perforator flap has a reliable blood supply and suitable thickness for the treatment of soft tissue defects at extremities. The technique is easily performed with reliable results.
