Abstract：
OBJECTIVE: We recently reported the first controlled Doppler ultrasonography (US) study demonstrating increased common femoral vein (CFV) thickness in Behçet\'s Disease (BD). Standard lower extremity venous Doppler US is performed in erect position. In order to confirm accuracy and applicability of method, we measured CFV thickness in both supine and standing positions in this study.
METHODS: We included sex and age-matched 42 BD patients and 41 healthy controls (HCs). After routine visits, bilateral CFV thickness was measured with Doppler US both in supine and standing positions.
RESULTS: Bilateral CFV thickness was significantly higher in BD than in HC. There were no statistically significant differences in measurements of CFV wall thickness between standing and supine positions in both groups.
CONCLUSIONS: CFV measurement by Doppler US is a new and non-invasive diagnostic tool for the diagnosis of BD. Our study confirmed that patient position does not affect CFV wall thickness measurement for diagnosis of BD.

摘要：
目的：我们最近报道了首例对照多普勒超声（US）研究，证实Behçet病（BD）患者股总静脉（CFV）厚度增加。标准下肢静脉多普勒超声在直立位置进行。为了确认方法的准确性和适用性，在这项研究中,我们测量了仰卧位和站立位的CFV厚度.
方法：我们纳入了性别和年龄匹配的42名BD患者和41名健康对照（HCs）。例行访问后，采用多普勒超声在仰卧位和站立位测量双侧CFV厚度.
结果：BD的双侧CFV厚度明显高于HC。两组的站立和仰卧位之间的CFV壁厚测量结果没有统计学上的显着差异。
结论：通过多普勒超声测量CFV是诊断BD的一种新的非侵入性诊断工具。我们的研究证实，患者的位置不会影响诊断BD的CFV壁厚测量。
