유리 동맥화 정맥피판술을 이용한 수지 굴곡구축의 치료

Purpose : The aim of this study was to evaluate the efficacy of arterialized venous flap in finger flexion contracture correction. Materials and methods : From 2002 to 2004, we have performed 10 arteriaized venous flap for treatment of severe flexion contracture in digit. The duration of flexion contracture was from 1 year to 50 years. The cause of contracture were bum scar(7 cases), postoperative contracture(2 cases) and other(l case). We evaluated the survival of flap, flap size, recovery of flexion contracture and subjective satisfaction. Results : All arterialized venous flap survived. The marginal minimal skin necrosis developed in 2 cases. The flap size was average $5.2{\times}3.5cm$. The recovery of flexion contracture was 87% compared with non affected side. 9 patients(90%) satisfied the results of operation. Conclusion : Arterialized venous flap is one of the useful procedure in treatment of finger flexion contracture because it has many advantages such as thin and good quality, variable length of pedicle, preservation of major vascular pedicle, less operation time and in addition possibility of various modifications.
