Chronic venous insufficiency is the most common vascular disease in the adult population. However, randomized clinical trials (RCTs) comparing therapeutic options are limited.
A total of 180 patients with saphenofemoral junction and great saphenous reflux detected on duplex were randomized to either ultrasound-guided radiofrequency ablation (RFA) or standard surgical treatment. The study participants blindly chose an assignment card that placed them in either group A (ultrasound-guided RFA of the great saphenous vein [GSV]; n = 90); or group B (surgical management n = 90). Patients were followed up for 24 months.
The primary occlusion rate in group A was 94.5% versus 100% in group B. Radiofrequency ablation had a lower overall complication rate (P = .02) and shorter post-intervention hospital stay (P = .001). Kaplan-Meier analysis showed no significant differences in recurrence rates at 24 months follow-up (P = .45). Radiofrequency ablation was significantly more expensive (P = .003).
Great saphenous vein occlusion was achieved efficiently in 94% of our group using RFA with minimal complications and obvious advantages as compared to standard surgery.
慢性静脉功能不全是成年人中最常见的血管疾病。然而,比较治疗选择的随机临床试验(RCT)有限。
共有 180 名在双功超声检查中发现股隐连接处和大隐静脉反流的患者被随机分配到超声引导射频消融(RFA)或标准手术治疗组。研究参与者盲选分配卡,将他们分配到 A 组(超声引导大隐静脉[GSV]射频消融;n=90)或 B 组(手术治疗 n=90)。患者随访 24 个月。
A 组的主要闭塞率为 94.5%,B 组为 100%。射频消融的总体并发症发生率较低(P=.02),术后住院时间较短(P=.001)。Kaplan-Meier 分析显示,24 个月随访时的复发率无显著差异(P=.45)。射频消融的费用明显更高(P=.003)。
与标准手术相比,RFA 可有效实现大隐静脉闭塞,并发症少,具有明显优势,闭塞率达到 94%。
