Survival rates and risk factors for failure using an interposition vein graft for fingertip amputations with segmental vessel defects.

This study demonstrates that the survival rate (80.8%) of the vein graft in fingertip amputation with segmental vessel defects was shown to be a possible option to increase the survival rates in case with segmental vessel defects where simple anastomosis could not be performed. However, avulsion type and zone II amputation are important risk factors of replantation failures.
