Venous flaps are nonphysiologic flaps in which the venous system replaces the vascular circuit found in conventional flaps, serving as inflow as well as outflow. Although a main concern with venous flaps has been their reliability, this can be improved by manipulating their physiology using shunt restriction. The soft, pliable tissue provided by venous flaps coupled with the low donor site morbidity and ease of flap harvest make them ideal for coverage of moderate-sized facial defects, which may be too large for local options yet too small for conventional free flaps. We report the use of a large, 70 cm arterialized venous free flap to reconstruct a complex forehead deficit after basal cell carcinoma resection. Furthermore, we present the first report of the successful use of valvulotomes in the case of a large, reverse flow arterialized venous flap where several in-series valves were found to prevent adequate perfusion of the flap. Upon removal of the valves, complete perfusion of the flap was achieved.
静脉皮瓣是一种非生理性皮瓣,其中静脉系统取代了传统皮瓣中的血管回路,兼具流入和流出功能。尽管静脉皮瓣一直存在可靠性方面的主要问题,但可通过使用分流限制来调节其生理功能加以改善。静脉皮瓣所提供的柔软、柔韧组织,再加上供区发病率低以及皮瓣切取容易,使其成为修复中等大小面部缺损的理想选择,这些缺损对于局部修复选择来说可能太大,而对于传统游离皮瓣来说又太小。我们报告使用一块70厘米的大型动脉化静脉游离皮瓣修复基底细胞癌切除术后的复杂前额缺损。此外,我们首次报告了在一例大型逆流动脉化静脉皮瓣中成功使用瓣膜刀的情况,该皮瓣发现有多个串联瓣膜阻碍皮瓣充分灌注。去除瓣膜后,皮瓣实现了完全灌注。
