Supermicrosurgical lymphaticovenular anastomosis (LVA) has become a useful option for the treatment of compression-refractory lymphedema with its effectiveness and less invasiveness. It is important to make as many bypasses as possible for better treatment results of LVA operation. We report a secondary lymphedema case successfully treated using a modified lambda-shaped LVA. A 62-year-old female with secondary lower extremity lymphedema (LEL) refractory to conservative treatments underwent LVA operation. A modified lambda-shaped LVA was performed at the left groin. In modified lambda-shaped LVA, two lymphatic vessels were transected, and both ends of the proximal and distal sides were converged respectively for an end-to-side and end-to-end anastomoses to one vein. Using modified lambda-shaped LVA, four lymph flows of two lymphatic vessels could be bypassed into a vein. Six months after the LVA surgery, her left LEL index decreased from 261 to 247, indicating edematous volume reduction. Modified lambda-shaped LVA effectively bypasses all lymph flows from two lymphatic vessels, when only one large vein can be found in the surgical field.
超显微淋巴管静脉吻合术(LVA)因其有效性和微创性,已成为治疗压迫难治性淋巴水肿的一种有效选择。为了获得更好的LVA手术治疗效果,尽可能多地进行旁路吻合至关重要。我们报告了一例使用改良λ形LVA成功治疗的继发性淋巴水肿病例。一名62岁女性,患有保守治疗无效的继发性下肢淋巴水肿(LEL),接受了LVA手术。在左腹股沟进行了改良λ形LVA。在改良λ形LVA中,切断两根淋巴管,近端和远端的两端分别汇合,与一根静脉进行端侧和端端吻合。使用改良λ形LVA,两根淋巴管的四股淋巴流可以旁路进入一根静脉。LVA手术后6个月,她的左LEL指数从261降至247,表明水肿体积减小。当在手术视野中只能找到一根大静脉时,改良λ形LVA能有效地使两根淋巴管的所有淋巴流旁路。
