Chronic venous insufficiency (CVI) is the result of outflow obstruction, reflux or a combination of both. Noninvasive tests detect an quantify obstruction and reflux if present and define the anatomic localisation of the abnormality. In evaluating CVI noninvasive tests combine physiologic and imaging techniques. These tests are widely available, simple, quick and cost-effective and therefore they are the methods of choice for initial objective evaluation. Different tests provide answers to different questions. The optimum clinically useful information can be now obtained using only three instruments: pocket Doppler, duplex or color duplex scanner and air plethysmography. The value of ambulatory venous pressure, photoplethysmography and light reflection reography, air plethysmography, duplex and color duplex scanning to assess reflux and the value of tests to assess out-flow obstruction are presented. Pooled data collected from large studies are also presented for reference. Qualitative and quantitative assessment of CVI are useful both for clinical assessment and to evaluate the effect of treatments.
慢性静脉功能不全（CVI）是静脉流出道梗阻、反流或两者兼有的结果。如果存在梗阻和反流，非侵入性检查可检测并量化它们，并确定异常的解剖定位。在评估CVI时，非侵入性检查结合了生理和成像技术。这些检查广泛可用、简单、快速且具有成本效益，因此它们是初始客观评估的首选方法。不同的检查回答不同的问题。现在仅使用三种仪器即可获得最佳的临床有用信息：袖珍多普勒、双功或彩色双功扫描仪以及空气容积描记法。本文介绍了动态静脉压、光电容积描记法和光反射体积描记法、空气容积描记法、双功和彩色双功扫描评估反流的价值以及评估流出道梗阻的检查的价值。还提供了从大型研究中收集的汇总数据以供参考。CVI的定性和定量评估对于临床评估和评估治疗效果均有用。
