Abstract

Objectives: To evaluate common femoral vein thickness (CFVT) as a diagnostic tool in Brazilian patients with Behçet's disease (BD) and to analyse associations between increased CFVT and disease features.

Methods: A cross-sectional study was performed including 100 BD patients and 100 controls. The CFVT and the diameters of great saphenous vein (GSV), and small saphenous vein (SSV) were measured by Doppler ultrasound.

Results: BD patients had higher right CFVT [0.600mm (0.500-0.700) vs. 0.525mm (0.450-0.637); p=0.012] and left CFVT [0.550mm (0.450-0.650) vs. 0.500mm (0.450-0.550); p=0.004] compared to controls. Vascular involvement of BD and previous deep venous thrombosis were associated with increased CFVT (p<0.05). The number of vascular events correlated with right and left CFVT (Rho = 0.475 p=0.030 and Rho = 0.429 p=0.052, respectively). The 0.575mm cut-off point of right and left CFVT had area under the curve (AUC) of 0.602; 95% confidence interval (95% CI): 0.524-0.680 and AUC: 0.615; 95% CI: 0.537-0.693, respectively. The right and left CFVT had a sensitivity for BD diagnosis of 52% and 43%, and a specificity of 64% and 77%, respectively. No significant differences were found between BD patients and controls regarding the GSV and SSV diameters in both legs (p>0.05).

Conclusions: In this study, CFVT measurement was not shown to be a reliable diagnostic test for BD. CFVT was increased in BD patients presenting vascular involvement and correlated with the number of previous events.

在非流行区评估股总静脉厚度作为诊断贝赫切特氏病的工具。
目的评估作为诊断工具的股总静脉厚度(CFVT)对巴西贝赫切特病(BD)患者的影响,并分析CFVT增加与疾病特征之间的关联:这项横断面研究包括 100 名贝赫切特病患者和 100 名对照者。多普勒超声测量了CFVT以及大隐静脉(GSV)和小隐静脉(SSV)的直径:结果:与对照组相比,BD 患者的右侧 CFVT [0.600mm (0.500-0.700) vs. 0.525mm (0.450-0.637); p=0.012]和左侧 CFVT [0.550mm (0.450-0.650) vs. 0.500mm (0.450-0.550); p=0.004]更高。BD血管受累和既往深静脉血栓形成与CFVT增加有关(P0.05):在这项研究中,CFVT 测量未被证明是一种可靠的 BD 诊断测试。在出现血管受累的 BD 患者中,CFVT 增加,并与既往事件的数量相关。
