BACKGROUND
The purpose of this study is to decrease the incidence of venous congestion occurring in the reversed flow posterior interosseous artery flap used for coverage of hand defects.
METHODS
This may be achieved by studying the incidence of venous congestion in flaps including only 1 perforator and comparing the results with others including more than 1 perforator both in small and large sized flaps.
RESULTS
This study showed that inclusion of only 1 perforator in the flap decreased the incidence of venous congestion with complete flap loss in flaps to 5%. Also, it decreased the incidence of venous congestion with partial flap loss in flaps to 10%.
CONCLUSIONS
The small sized reversed flow posterior interosseous artery flap should be less than 40 cm and should include only 1 perforator to decrease the incidence of venous congestion with partial and complete loss of the flap. The level of evidence for this study is the type II prospective comparative study.
背景
本研究的目的是降低用于覆盖手部缺损的逆行骨间后动脉皮瓣中静脉淤血的发生率。
方法
这可以通过研究仅包含1个穿支的皮瓣中静脉淤血的发生率，并将结果与包含1个以上穿支的大小皮瓣的结果进行比较来实现。
结果
本研究表明，皮瓣中仅包含1个穿支可将皮瓣完全丢失时静脉淤血的发生率降低至5%。此外，它还将皮瓣部分丢失时静脉淤血的发生率降低至10%。
结论
小型逆行骨间后动脉皮瓣应小于40 cm，且应仅包含1个穿支，以降低皮瓣部分和完全丢失时静脉淤血的发生率。本研究的证据水平为II型前瞻性比较研究。
