Radial forearm flaps with venous compromise: correlations between salvage techniques and their rates of success.

We retrospectively analysed the reliability of anastomosis of the deep venous system as a salvage technique for a free radial forearm flap that has developed venous compromise. The primary predictors were the salvage techniques, which comprised anastomosis of the deep venous system and a repeat of the original anastomosis, and the primary outcome measure was the rate of success. The potential confounders included original venous outflow, the original causes of the venous compromise, and the number of venous anastomoses.
