Vascular ultrasonography (VU) is the examination of choice for studying the superficial venous system of the lower limbs and using VU to measure the diameters of saphenous veins could provide parameters for planning surgery.
To employ VU to identify the diameters of great saphenous veins free from reflux in women and determine their relationships with age, height, CEAP classification, and body mass index (BMI).
This was a cross-sectional study in women with symptoms of primary chronic venous insufficiency (CEAP C0, 1, or 2) with no previous varicose vein surgery and no reflux detected by VU. The diameters of great saphenous veins (GSV) at the junction, thigh, and leg were measured with VU and correlated with age, height, CEAP clinical classification, and BMI.
We assessed 204 limbs in 146 women. The GSV diameters measured were 6.5 mm at the saphenofemoral junction, 4.0 mm at the proximal thigh, 3.0 mm at the mid thigh, distal thigh, and knee and 2.5 mm at the leg. In all segments measured, there were statistically significant differences (p<0.05) when diameters were correlated with BMI. There were no statistically significant differences when diameters were correlated with CEAP class, height, or age.
We observed that the diameters of great saphenous veins free from reflux were independent of CEAP clinical classes 0/1 or 2; age; and height. However, GSV diameters were significantly related to patients’ BMI.
血管超声检查（VU）是研究下肢浅静脉系统的首选检查方法，利用VU测量大隐静脉直径可为手术规划提供参数。
采用VU确定无反流的女性大隐静脉直径，并确定其与年龄、身高、CEAP分级和体重指数（BMI）的关系。
这是一项横断面研究，研究对象为有原发性慢性静脉功能不全症状（CEAP C0、1或2）、既往无静脉曲张手术史且VU检查未发现反流的女性。用VU测量大隐静脉（GSV）在汇合处、大腿和小腿的直径，并将其与年龄、身高、CEAP临床分级和BMI进行相关性分析。
我们评估了146名女性的204条肢体。测量的GSV直径在隐股交界处为6.5mm，大腿近端为4.0mm，大腿中部、大腿远端和膝盖处为3.0mm，小腿处为2.5mm。在所有测量节段中，直径与BMI相关时存在统计学显著差异（p<0.05）。直径与CEAP分级、身高或年龄相关时无统计学显著差异。
我们观察到无反流的大隐静脉直径与CEAP临床分级0/1或2、年龄和身高无关。然而，GSV直径与患者的BMI显著相关。
