  • REPAIR OF SOFT TISSUE DEFECTS OF LOWER EXTREMITY BY USING CROSS-BRIDGE CONTRALATERAL DISTALLY BASED POSTERIOR TIBIAL ARTERY PERFORATOR FLAPS OR PERONEAL ARTERY PERFORATOR FLAPS

    Objective To discuss the feasibil ity of repairing soft tissue defects of lower extremity with a distally based posterior tibial artery perforator cross-bridge flap or a distally based peroneal artery perforator cross-bridge flap. Methods Between August 2007 and February 2010, 15 patients with soft tissue defect of the legs or feet were treated. There were 14 males and 1 female with a mean age of 33.9 years (range, 25-48 years). The injury causes included traffic accident in 8 cases, crush injury by machine in 4 cases, and crush injury by heavy weights in 3 cases. There was a scar (22 cm × 8 cm atsize) left on the ankle after the skin graft in 1 patient (after 35 months of traffic accident). And in the other 14 patients, the defect locations were the ankle in 1 case, the upper part of the lower leg in 1 case, and the lower part of the lower leg in 12 cases; the defect sizes ranged from 8 cm × 6 cm to 26 cm × 15 cm; the mean interval from injury to admission was 14.8 days (range, 4-28 days). Defects were repaired with distally based posterior tibial artery perforator cross-bridge flaps in 9 cases and distally based peroneal artery perforator cross-bridge flaps in 6 cases, and the flap sizes ranged from 10 cm × 8 cm to 28 cm × 17 cm. The donor sites were sutured directly, but a spl it-thickness skin graft was used in the middle part. The pedicles of all flaps were cut at 5-6 weeks postoperatively. Results Distal mild congestion and partial necrosis at the edge of the skin flap occurred in 2 cases and were cured after dressing change, and the other flaps survived. After cutting the pedicles, all flaps survived, and wounds of recipient sites healed by first intention. Incisions of the donor sites healed by first intention, and skin graft survived. Fifteen patients were followed up 7-35 months with an average of 19.5 months. The color and texture of the flaps were similar to these of the reci pient site. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system, the mean score was 87.3 (range, 81-92). Conclusion A distally based posterior tibial artery perforator cross-bridge flap or a distally based peronealartery perforator cross-bridge flap is an optimal alternative for the reconstruction of the serious tissue defect of ontralateral leg or foot because of no microvascular anastomosis necessary, low vascular crisis risk, and high survival rate.

  • DESIGN AND APPLICATION OF ANTEROLATERAL THIGH FREE FLAP WITH OBLIQUE BRANCH

    ObjectiveTo investigate the feasibility of the anterolateral thigh free flap with the oblique branch in reconstructing the soft tissue defects of lower extremity. MethodsBetween June 2009 and February 2013,12 patients (including 7 males and 5 females) with soft tissue defects of lower extremity were treated with the anterolateral thigh free flap with the oblique branch,aged from 8 to 42 years (median,32 years).The locations of soft tissue defect were the dorsum of the foot in 5 cases,the ankle and foot in 4 cases,the lower leg in 2 cases,and the distal foot in 1 case.All defects were associated with exposure of tendon and bone.The size of the wound was from 15 cm×7 cm to 27 cm×12 cm.The interval of injury and operation was 1 to 7 days (mean,3.7 days).The anterolateral thigh flap was pedicled with only the oblique branch in 7 patients,and with the both descending branch and oblique branch in 5 patients,and the size of flap was from 17 cm×9 cm to 30 cm×15 cm.The donor sites were repaired by suture in 3 patients,and by skin graft in 9 patients. ResultsDistal skin flap necrosis occurred in 1 case,and was cured after dressing change and skin graft.The other flaps survived,and the donor site healed primarily.The follow-up time was from 10 months to 2 years (mean,18 months).Thinning operation was performed in 3 cases,and the other flaps recovered pain and warm sensation with good appearance. ConclusionIt is a safe and effective method to reconstruct soft tissue defects of the lower extremity with the anterolateral thigh flap pedicled with the oblique branch.
