External valvuloplasty (eVP) is a reconstructive surgical method to repair the function of the terminal and preterminal valves. We evaluated the 6-month outcomes of eVP regarding the diameter of the great saphenous vein (GSV).
Patients from five vein centres were included in this observational study. Follow-up involved detailed duplex sonography of the GSV. The venous clinical severity score (VCSS) and the C class of the clinical, aetiologic, anatomic and pathophysiologic (CEAP) classification were recorded.
We enrolled 210 patients, with a follow-up rate of 58%; eVP was sufficient in 95.24% of the patients. The GSV diameters decreased significantly from 4.4 mm (standard deviation (SD): 1.39) to 3.9 (SD: 1.12), 4 cm distal to the saphenofemoral junction (SFJ); from 3.7 mm (SD: 1.10) to 3.5 mm (SD: 1.02) at the mid-thigh; from 3.6 mm (SD: 1.14) to 3.3 mm (SD: 0.94) at the knee and from 3.1 mm (SD: 0.99) to 2.9 mm (SD: 0.78) at the mid-calf. VCSS decreased significantly from 4.76 (SD: 2.13) preoperatively to 1.77 (SD: 1.57) 6 months postoperatively.
GSV function can be restored by eVP; diameters over the total length of the GSV decreased significantly.
外瓣膜成形术（eVP）是一种修复终末和近末端瓣膜功能的重建性外科方法。我们评估了 eVP 对大隐静脉（GSV）直径的 6 个月结果。
本观察研究纳入了来自五个静脉中心的患者。随访包括 GSV 的详细双功能超声检查。记录静脉临床严重程度评分（VCSS）和临床、病因、解剖和病理生理（CEAP）分类的 C 级。
我们共纳入 210 例患者，随访率为 58%；95.24%的患者 eVP 足够。GSV 直径从 SFJ 以下 4cm 处的 4.4mm（标准差（SD）：1.39）显著减小至 3.9（SD：1.12）；从大腿中部的 3.7mm（SD：1.10）减小至 3.5mm（SD：1.02）；从膝关节的 3.6mm（SD：1.14）减小至 3.3mm（SD：0.94）；从中腿的 3.1mm（SD：0.99）减小至 2.9mm（SD：0.78）。VCSS 从术前的 4.76（SD：2.13）显著降低至术后 6 个月的 1.77（SD：1.57）。
eVP 可恢复 GSV 功能；GSV 的总长度上的直径显著减小。
