•The overall surgery success rate of ETS anastomosis was 96.6%.•The occurrence of the ETS anastomosis-related venous thrombosis was 2.3% (4/117).•ETS anastomosis success rate was not affected by local condition of surgery site.
IntroductionThe success of end-to-side (ETS) venous anastomosis primarily depends on several mandatory factors including recipient vessel selection and reconstruction site. This retrospective study was designed to analyze the success rate of ETS venous anastomosis for free flap extremity reconstruction.MethodsBetween 2009 and 2011, ETS venous anastomosis was performed in 117 patients to reconstruct soft tissue defects of extremity at Nanjing Drum Tower Hospital. The patients were divided into three groups: (1) only one large recipient vein left, (2) two deep venas, (3) one deep vein and one superficial vein. Medical records and the follow-up data were retrospectively reviewed. The success rates of the three groups were compared with Chi-squared test.ResultsTotally, 5, 52, and 60 patients were included in Group 1, Group 2, and Group 3, respectively. The overall surgery success rate was 96.6% (113/117) with four failures: zero in Group 1, two in Group 2 (2/52, 3.8%) and two in Group 3 (2/60, 3.3%), due to venous thrombosis. The re-anastomosis rate in re-exploration in Group 1, 2 and 3 was 0%, 1.9% (1/52), and 1.7% (1/60), respectively. No complication was observed during the operation.DiscussionNo statistical difference was observed in flap failure rate among the three different types of ETS anastomosis. This suggests that differences of the ETS anastomosis surgical site might not affect the surgery success rate.ConclusionThese results confirmed that the success rate of ETS anastomosis was not affected by the local conditions of surgery site.
