Purpose: The purpose of this study was to evaluate the clinical results of anterolateral thigh free flap on soft tissue defect following wide excision in malignant soft tissue tumor of lower extremities.
Methods: Between February 2005 to April 2010, we followed up 19 cases who were undergoing anterolateral thigh free flap because of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity, including 9 cases were heel, 5 cases in foot, 3 cases in ankle, 2 cases in knee and leg. We observed that of implanted area\’s color, peripheral circulation at 3, 5, 7 days after operation and evaluated operating time, amount of hemorrhage, implanted skin necrosis, additional operations, complications. And we also evaluated the oncologic results, including local recurrence, metastasis, and morbidity.
Results: Average operation time of wide excision and anterolateral thigh free flap was 7 hour 28 minutes. 18(94.7%) of total 19 cases showed successful engraftment, on the other hand, failure of engraftment due to complete necrosis of flap in 1 case. In 18 cases with successful engraftment, reoperation was performed in 4 cases. Among them, removal of hematoma and engraftment of flap after bleeding control was performed in 3 cases, because of insufficient circulation due to the hematoma. In the remaining 1 case, graft necrosis due to flap infection was checked, and grafted after combination of wound debridement and conservative treatment such as antibiotics therapy, also skin graft was performed at debrided skin defect area. Skin color change was mainly due to congestion with hematoma, flap was not observed global congestion or necrosis except 4 cases which shows partial necrosis on margin that treated with conservative therapy.
Conslusions: Anterolateral thigh free flap could be recommended for reconstruction of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity.
