下肢手术后有症状的下肢深静脉血栓形成

目的：探讨下肢手术后有症状的下肢深静脉血栓形成的临床特点，早期诊断方法和预防措施，方法：对5例支手术后发生有症状的下肢深静脉血栓形成患者的临床表现和彩色多普勒结果进行分析。结果：下肢手术后小腿出现疼痛是下肢深静脉血栓形成最早出现并具有很高诊断价值的临床特点，手术后肢体加压包扎是一促进下肢深静脉血栓形成的可能因素。结论：下肢手术后出现小腿后侧疼痛时应考虑下肢深静脉血栓形成的可能，彩色多普勒检查可明确诊断，对高危患者围手术期应采取综合预防措施。

Symptomatic Deep Venous Thrombosis after Lower Extremity Operation
