The preoperative assessment of varicose veins usually requires the use of ultrasound methods to specify and localize the various sources of reflux in the saphenous junctions, perforating veins and saphenous branches. Continuous wave Doppler (CW) is the basic technique used to investigate reflux and usefully completes clinical examination of varicose veins. Duplex-scan provides morphological analysis of the veins and studies the direction of flow in a precise site. It is particularly useful to study the saphenous-junction, perforating veins and deep vems. Color Doppler imaging (CDI) offers the advantage of duplex-scanning, withe visualization of great volumes of measurement whit blue or red colour-coding according to the direction of flow. All haemodynamic and morphological findings must be reported on a diagram to establish "mapping" of pathological veins.
静脉曲张的术前评估通常需要使用超声方法来明确和定位大隐静脉汇合处、穿通静脉和大隐静脉分支中各种反流的来源。连续波多普勒（CW）是用于研究反流的基本技术，它有效地完善了静脉曲张的临床检查。双功超声扫描可提供静脉的形态分析，并精确研究特定部位的血流方向。它对于研究大隐静脉汇合处、穿通静脉和深静脉特别有用。彩色多普勒成像（CDI）具有双功超声扫描的优势，能够根据血流方向用蓝色或红色编码直观显示大量测量数据。所有血流动力学和形态学检查结果都必须记录在图表上，以建立病理性静脉的“图谱”。
