The purpose of this study was to determine the occlusion rate of incompetent great saphenous veins (GSVs) and small saphenous veins (SSVs) treated with radiofrequency ablation (RFA) and individualize variables associated with recanalization.
A retrospective review of 311 veins (256 GSVs and 55 SSVs) in 211 patients [177 women, 34 men; mean age, 45 years±12 (SD) (range: 18-75 years)] with incompetent GSVs and/or SSVs who were treated using new-generation RFA catheters was performed. The clinical results, occlusion rates, and variables associated with recanalization for the incompetent GSVs and SSVs were analyzed.
No major complications were observed in the study population. Ten months after RFA, the occlusion rate was 89% (227/256) for GSVs and 91% (50/55) for SSVs. An increased pre-procedure diameter of the incompetent GSVs was associated with a higher rate of recanalization (OR: 0.825; 95% CI: 0.715-0.952) (P<0.05). No significant differences in age, gender, and side of treated veins were found between patients with recanalization of treated veins and those without recanalization.
Our results show that pre-procedure diameter of the GSV is the single risk factor for recanalization after RFA.
本研究旨在确定接受射频消融（RFA）治疗的大隐静脉（GSV）和小隐静脉（SSV）功能不全的闭塞率，并确定与再通相关的个体化变量。
对211例大隐静脉和/或小隐静脉功能不全患者（177例女性，34例男性；平均年龄45岁±12岁（标准差）（范围：18 - 75岁））使用新一代RFA导管治疗的311条静脉（256条大隐静脉和55条小隐静脉）进行回顾性研究。分析了大隐静脉和小隐静脉功能不全的临床结果、闭塞率以及与再通相关的变量。
研究人群中未观察到重大并发症。RFA治疗10个月后，大隐静脉闭塞率为89%（227/256），小隐静脉闭塞率为91%（50/55）。功能不全的大隐静脉术前直径增加与再通率较高相关（比值比：0.825；95%置信区间：0.715 - 0.952）（P<0.05）。治疗静脉再通患者与未再通患者在年龄、性别和治疗静脉侧别方面未发现显著差异。
我们的结果表明，大隐静脉术前直径是RFA治疗后再通的单一危险因素。
