High-energy lower limb trauma may result in complex defects with extensive vascular damage. Free flap reconstruction in these cases may require vein grafts to reach healthy proximal recipient vessels. Vascular loops are an increasingly popular technique in managing recipient vessels in reconstructive microsurgery, especially in the lower limb. The use of an entire omega segment of the greater saphenous vein had not been described before but offered two advantages: the caliber match for arterial repair was better using one of the limbs of the omega compared with the parent greater saphenous vein, and it allowed two venous anastomoses instead of one. A case report of a fully bifurcated segment of the greater saphenous vein as a vascular loop for microvascular reconstruction in the lower limb is presented. To the best of the authors' knowledge, no similar case has been reported previously.
高能下肢创伤可能导致伴有广泛血管损伤的复杂缺损。在这些病例中，游离皮瓣重建可能需要静脉移植来连接健康的近端受区血管。血管袢在重建显微外科中管理受区血管的技术中越来越受欢迎，尤其是在下肢。此前尚未描述过使用大隐静脉的完整ω段，但它具有两个优点：与大隐静脉主干相比，使用ω段的一个分支进行动脉修复时口径匹配更好，并且它允许进行两个静脉吻合而不是一个。本文介绍了一例将大隐静脉完全分叉段用作下肢微血管重建血管袢的病例报告。据作者所知，此前尚未报道过类似病例。
