The aim of this study was to assess the value of duplex ultrasound examination in establishing diagnosis in acutely swollen and painful lower limbs, and to examine how often the diagnosis of superficial and/or deep venous thrombosis can be made in the symptomatic legs.
Venous duplex scan examination was performed on 188 extremities of 180 ambulatory outpatients. The examination included testing patency and competency of the deep and superficial veins. The ultrasound study was also extended to finding soft tissue abnormalities.
Of the 188 lower limbs venous thrombosis was found on 82 occasions: 29 legs contained deep venous thrombosis only; 23 legs presented with superficial thrombophlebitis as a sole venous pathology; and in 30 cases superficial and deep venous thrombosis coexisted. In those 106 limbs where venous thrombosis was not present the most frequent positive ultrasound findings were incompetent leg veins or soft tissue masses (Baker's cyst and calf haematoma).
The variety of pathological processes related to the lower limb veins and the extravascular tissue suggest that routine, "detailed" ultrasound scanning would be indicated in all acutely symptomatic legs with a suspected venous disorder. The important diagnostic information so gained provides guidance to the most appropriate treatment strategy.
本研究旨在评估双功超声检查在诊断急性肿胀和疼痛下肢中的价值，并探讨有症状下肢诊断浅表和/或深静脉血栓形成的频率。
对180名门诊患者的188条肢体进行静脉双功扫描检查。检查包括检测深静脉和浅静脉的通畅性和功能。超声检查还扩展到发现软组织异常。
在188条下肢中，有82例发现静脉血栓形成：29条腿仅存在深静脉血栓形成；23条腿表现为单纯的浅表血栓性静脉炎；30例同时存在浅表和深静脉血栓形成。在106条未出现静脉血栓形成的肢体中，最常见的超声阳性发现是腿部静脉功能不全或软组织肿块（贝克囊肿和小腿血肿）。
与下肢静脉和血管外组织相关的各种病理过程表明，对于所有疑似静脉疾病的急性有症状下肢，应进行常规的“详细”超声扫描。由此获得的重要诊断信息可为最合适的治疗策略提供指导。
