It is estimated that between 5% to 20% of the adult population in developed countries is affected by chronic venous insufficiency (CVI), thus being the most frequent vascular disorder. Recent studies show that, in most CVI patients, their junctions are competent and the correlated superficial reflux is present along the saphenous vein. Objective of the study was to correlate the presence and distribution of reflux in the saphenous vein with the signs and symptoms of CVI, through CEAP, in female patients.
Record review of patients with CVI signs and symptoms who underwent clinical and ultrasound examinations in order to classify them according to CEAP. The sample was divided into three groups according to the presence of saphenous vein insufficiency: Group I-SSV, Group II-GSV, and Group III-SSV and GSV.
A total of 312 lower limbs of 259 female patients aged between 15 and 85 years were examined. The most prevalent clinical classes in the three groups were C2 (44.55%) and C3 (46.48%). Four patterns of reflux were identified in isolated SSV, with the highest incidence of proximal reflux (69.23%). SPJ impairment was most likely to occur in clinical cases of greater severity. Five patterns of reflux were identified in GSV, with the proximal one the most prevalent (64.42%).
There is a correlation between the clinical severity of CVI and the reflux along the SSV in association with GSV; the risk of moderate to high clinical severity in group III was 3.6 times higher than in group I and 4.6 times higher than group II.
据估计，发达国家5%至20%的成年人口受慢性静脉功能不全（CVI）影响，这是最常见的血管疾病。最近的研究表明，在大多数CVI患者中，其瓣膜功能正常，且沿隐静脉存在相关的浅静脉反流。本研究的目的是通过CEAP对女性患者进行评估，以关联隐静脉反流的存在和分布与CVI的体征和症状。
回顾性记录有CVI体征和症状且接受临床及超声检查的患者，以便根据CEAP进行分类。根据隐静脉功能不全的情况将样本分为三组：第一组为小隐静脉（SSV）组，第二组为大隐静脉（GSV）组，第三组为SSV和GSV组。
共检查了259名年龄在15至85岁之间女性患者的312条下肢。三组中最常见的临床分级为C2（44.55%）和C3（46.48%）。在孤立的SSV中识别出四种反流模式，近端反流发生率最高（69.23%）。SPJ损伤在病情较重的临床病例中最易发生。在GSV中识别出五种反流模式，近端反流最为常见（64.42%）。
CVI的临床严重程度与SSV合并GSV的反流之间存在相关性；第三组中临床中重度的风险比第一组高3.6倍，比第二组高4.6倍。
