Arterialized venous free flaps with a single straight venous axis may require redirection of either the efferent or afferent vein for anastomosis to the digital vessels. To simplify these flaps, the authors propose use of an arterialized venous free flap having 2 parallel veins that does not require redirection of the veins.
The authors performed 44 arterialized venous free flaps having 2 parallel veins for the reconstruction of digital soft tissue defects. The mean area of coverage was 6.5 cm(2). The donor sites included the volar aspect of the distal forearm in 35 cases, the thenar area in 8 cases, and the dorsal aspect of the foot in 1 case.
Thirty-nine of the 44 flaps survived. Complete flap necrosis occurred in 5 cases, and flap congestion was seen in 28 cases.
The authors had satisfactory results using arterialized venous free flaps having 2 parallel veins. By using these flaps, the authors were able to simplify the technique of arterialized venous flaps.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
具有单一笔直静脉轴的动脉化静脉游离皮瓣可能需要将传出静脉或传入静脉重新定向，以便与指血管进行吻合。为简化这些皮瓣，作者提议使用具有两条平行静脉且无需静脉重新定向的动脉化静脉游离皮瓣。
作者进行了44例具有两条平行静脉的动脉化静脉游离皮瓣手术，用于修复手指软组织缺损。平均覆盖面积为6.5平方厘米。供区包括35例在前臂远端掌侧，8例在鱼际区，1例在足背。
44例皮瓣中有39例存活。5例发生完全皮瓣坏死，28例出现皮瓣充血。
作者使用具有两条平行静脉的动脉化静脉游离皮瓣取得了满意的结果。通过使用这些皮瓣，作者能够简化动脉化静脉皮瓣技术。
研究类型/证据水平：治疗性IV级。
