Abstract

PURPOSE
The venous flap is used as an alternative method to the standard free flap for the management of small and thin soft tissue defects. Especially, the venous flap has advantages of being thin, easy harvest and various donor sites, as well as it having lower morbidity. Yet their clinical applications have been limited by their unstable postoperative course and also by their complications such as partial necrosis. The aim of this study is to extend the clinical indications of venous flaps with using various methods. METHODS: From May 2005 to March 2006, total of 19 patients(21 cases) underwent various venous flaps for soft tissue defects as a result of trauma(15 cases), facial skin cancer(3 cases), chronic ulcer(1 case) and surgical wound for congenital anomaly(2 cases). The arterialized venous free flap were applied in 18 cases, the pure venous free flap was applied in 1 case and the pure venous pedicled flap were applied in 2 cases. Among them, two flow-through arterialized venous free flaps were applied that used the great saphenous vein to reconstructed major arteries as well as the injured skin and soft tissues in the arm. All the flap were harvested from the volar wrist(11 cases), dorsum of foot(5 cases), thenar(2 cases), and medial thigh(3 cases).
RESULTS
The sizes of the flap ranged from 0.75cm2 to 264cm2(mean size: 40.06cm2). The follow-up period ranged from two to twelve months. In the majority of cases, we obtained satisfying results, which was the excellent reconstruction of skin and soft tissue defects and especially in the case of limb salvage, replantation and cancer reconstruction. However, there were 5 cases of partial necrosis and 2 cases of complete failure. The donor sites were closed primarily in 7 cases and wound closure with skin graft were in 14 cases.
CONCLUSION
We conclude that the venous flap will not only be useful for reconstruction of small defect in the hand and foot, but also be useful for various other clinical indications.
