Abstract
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. The chi squared test, Fisher's exact test, and the Cochran-Mantel-Haenszel test were used for statistical analysis as appropriate. The final sample comprised 42 patients who required re-exploration for venous compromise. The salvage rates were 15/18 when anastomosis of the deep venous system was chosen as a salvage technique and 9/24 and when the original anastomosis was done again (p=0.003, OR 2.222, 95% CI 1.274 to 3.876). The salvage rate of venous compromise was higher in patients who had anastomoses of the deep venous system than in those in whom the original anastomosis was repeated.
