Venous ultrasonography identifies reflux patterns of the great and small saphenous veins (GSV, SSV), allowing evaluation of lower extremities for treatment planning and patient follow-up.
To determine progression of saphenous vein reflux patterns in women with primary venous valvular insufficiency.
Venous ultrasonography was performed in the extremities of 92 women, 43 ± 12 (23-77) years old, CEAP (clinical, aetiological, anatomical and pathological elements) clinical classes C1-C2. Two examinations were performed 33 ± 19 (8-89) months apart in patients without saphenous vein treatment. GSV and SSV reflux patterns were classified as segmental, multisegmental, distal, proximal, diffuse and normal. Prevalence was determined for each examination, separately for right and left extremities, and jointly. Prevalence was compared using χ2 statistics.
Reflux prevalence was higher for the GSV, 89% (164/184) and 88% (n = 162), than for the SSV, 24% (n = 45) and 30% (n = 56), respectively for first and second examinations (P < 0.001). Reflux pattern prevalence was not significantly different in the right and left extremities (1.0 > P > 0.14). Most prevalent patterns were (a) GSV segmental reflux initially, 41% (76/184), decreasing to 28% (52/184) (P = 0.009), and (b) GSV multisegmental reflux at the second examination, increasing from 26% (48/184) to 40% (73/184) (P = 0.006). Prevalence of other GSV or SSV reflux patterns did not change significantly (0.88 > P > 0.19).
We documented early findings and venous reflux progression in a specific population of women with varicose veins, reticular veins and telangiectasias. GSV segmental reflux was most prevalent initially, progressing to GSV multisegmental reflux.
静脉超声检查可识别大隐静脉和小隐静脉（GSV、SSV）的反流模式，有助于评估下肢情况，以制定治疗方案及对患者进行随访。
确定原发性静脉瓣膜功能不全女性患者隐静脉反流模式的进展情况。
对92名年龄为43±12（23 - 77）岁、CEAP（临床、病因、解剖和病理因素）临床分级为C1 - C2级的女性患者的双下肢进行静脉超声检查。在未接受隐静脉治疗的患者中，两次检查间隔33±19（8 - 89）个月。GSV和SSV反流模式分为节段性、多节段性、远端、近端、弥漫性和正常。分别对每次检查的右下肢、左下肢及双下肢联合确定每种反流模式的患病率。采用χ²检验比较患病率。
第一次和第二次检查时，GSV的反流患病率分别为89%（164/184）和88%（n = 162），高于SSV的反流患病率，分别为24%（n = 45）和30%（n = 56）（P < 0.001）。右下肢和左下肢的反流模式患病率无显著差异（1.0 > P > 0.14）。最常见的模式为：（a）最初GSV节段性反流占41%（76/184），降至28%（52/184）（P = 0.009）；（b）第二次检查时GSV多节段性反流从26%（48/184）增至40%（73/184）（P = 0.006）。其他GSV或SSV反流模式的患病率无显著变化（0.88 > P > 0.19）。
我们记录了患有静脉曲张、网状静脉和毛细血管扩张症的特定女性人群的早期发现及静脉反流进展情况。GSV节段性反流最初最为常见，随后进展为GSV多节段性反流。
