A cross-leg or cross-bridge free flap is frequently used for the reconstruction of leg defects in cases with no suitable recipient vessels in the vicinity of the defect. Here we report eight cases of leg reconstruction with a distally based posterior tibial artery cross-bridge flap without microvascular anastomosis technology. A distally based posterior tibial artery flap was elevated and used to reconstruct contralateral leg defects. A skin incision was made near the recipient wound to create a skin bridge, and a subcutaneous tunnel was made between the skin incision and the recipient wound for the vascular pedicle to pass over. All flaps survived completely without complications, except for a case with minor erosion in the donor site. Compared with a cross-leg or cross-bridge free flap, a distally based posterior tibial artery cross-bridge flap is reliable and versatile, leading to shorter operation duration and a lower risk of thrombosis in the vessel because microvascular anastomosis is not required.
跨腿或跨桥游离皮瓣常用于修复缺损附近无合适受区血管的腿部缺陷。我们报告了 8 例采用远端蒂胫后动脉跨桥皮瓣而无需血管吻合技术修复腿部缺陷的病例。切取远端蒂胫后动脉皮瓣，用于重建对侧腿部缺陷。在受区创面附近做一皮肤切口，形成皮桥，在皮桥与受区创面之间做一皮下隧道，使血管蒂通过。除一例供区有轻微侵蚀外，所有皮瓣均完全存活，无并发症。与跨腿或跨桥游离皮瓣相比，远端蒂胫后动脉跨桥皮瓣可靠且用途广泛，由于无需进行血管吻合，手术时间更短，血管发生血栓的风险更低。
