摘要

目的:隐静脉直径增大是隐静脉返流的常见后果。到目前为止,还没有关于韩国隐静脉直径与反流之间关系的报道。本研究的目的是探讨隐静脉反流与直径变化之间的关系。方法:2009年4月至2012年8月,将777例患者送往血管实验室进行静脉反流评估。b型显像测量大隐静脉直径,多普勒光谱示踪根据瓣膜关闭时间量化反流。应用受试者工作特征曲线分析确定预测反流的最佳隐静脉直径截止值。结果:正常大隐静脉和回流大隐静脉的平均直径分别为5.0±2.4 mm和6.4±2.0 mm。正常小隐静脉和回流小隐静脉的平均直径分别为3.1±1.3 mm和5.2±2.7 mm。正常GSV与回流GSV、SSV的直径差异分别为1.4 mm和2.1 mm,差异有统计学意义(P < 0.0001)。GSV阈值直径为5.05 mm对反流有最好的阳性预测值。5.05 mm处的敏感性为76%,特异性为60%。预测反流的最佳SSV直径为3.55 mm。3.55 mm的敏感性为87%,特异性为71%。结论:GSV直径≥5.05 mm对病理性反流的阳性预测价值最好。对于SSV病理性返流,最佳切断直径为3.55 mm。

The cutoff value of saphenous vein diameter to predict reflux.

The cutoff value of saphenous vein diameter to predict reflux.

Purpose: Increased saphenous vein diameter is a common consequence of saphenous vein reflux. Until now, there have been no reports about the correlation between diameter and reflux of saphenous vein in Korea. The aim of this study was to investigate the correlation between saphenous vein reflux and diameter changes.

Methods: From April 2009 to August 2012, 777 patients were sent to the vascular laboratory for evaluation of venous reflux. The diameter of the saphenous vein was measured with B-mode imaging, and reflux was quantified based on valve closure time using Doppler spectral tracings. Receiver operating characteristics curve analysis was applied to determine the best saphenous vein diameter cutoff for predicting reflux.

Results: The mean diameters of normal great saphenous vein (GSV) and refluxed GSV were 5.0 ± 2.4 mm and 6.4 ± 2.0 mm, respectively. The mean diameters of normal small saphenous vein (SSV) and refluxed SSV were 3.1 ± 1.3 mm and 5.2 ± 2.7 mm, respectively. The diameter differences between the normal and refluxed GSV and SSV were 1.4 mm and 2.1 mm, respectively, and these differences were statistically significant (P < 0.0001). A GSV threshold diameter of 5.05 mm had the best positive predictive value for reflux. The sensitivity and specificity at 5.05 mm were 76% and 60%, respectively. The best SSV diameter for predicting reflux was 3.55 mm. The sensitivity and specificity at 3.55 mm were 87% and 71%, respectively.

Conclusion: GSV diameter of ≥5.05 mm had the best positive predictive value for pathologic reflux. For pathologic reflux of SSV, the best cutoff diameter was 3.55 mm.
