Ultrasonic imaging provides a non-invasive assessment of the arterial and venous circulation in the lower limb and is accepted as a valuable diagnostic technique. Grey-scale images identify plaque and thrombus, duplex assessment provides a measurement of blood velocity through a vessel, and colour Doppler imaging enables the rapid localization of arterial stenoses and occlusions and the identification of incompetent veins. This article outlines the principles of the different techniques and presents normal images. Procedures for investigating arterial stenoses, superficial venous incompetence and deep venous thrombosis are described, abnormal images presented and the limitations discussed. It is hoped to provide an insight into the strengths and limitations of ultrasonic vascular investigations for those involved in tissue viability and ulcer management.
超声成像可对下肢的动静脉循环进行无创评估，是一种公认的有价值的诊断技术。灰阶图像可识别斑块和血栓，双功超声评估可测量血管内的血流速度，彩色多普勒成像能够快速定位动脉狭窄和闭塞，并识别功能不全的静脉。本文概述了不同技术的原理并展示了正常图像。描述了动脉狭窄、浅静脉功能不全和深静脉血栓形成的检查程序，展示了异常图像并讨论了局限性。希望能让参与组织活力和溃疡治疗的人员深入了解超声血管检查的优势和局限性。
