We performed preoperative and postoperative duplex ultrasonography examinations on both lower extremities in 128 patients undergoing 146 hip and knee reconstructive procedures. The results of the examinations were reviewed by an independent radiologist who specializes in these studies. Three of the 128 patients (146 procedures; 2.1%) had evidence of a deep venous thrombosis or other venous abnormality before surgery. Three additional patients developed a deep venous thrombosis after surgery, despite mechanical and pharmacologic prophylaxis. We have discontinued performing preoperative duplex ultrasonography prior to primary, uncomplicated total joint replacement of the lower extremities. We continue to perform duplex ultrasonography before surgery in patients at high risk, with a history of deep venous thrombosis or phlebitic syndrome, and in those who have previously had major surgery on the lower extremities.
我们对128例接受146例髋膝关节重建手术的患者双下肢进行了术前和术后双功超声检查。检查结果由一位专门从事这些研究的独立放射科医生进行评估。128例患者中有3例（146例手术；2.1%）在手术前有深静脉血栓形成或其他静脉异常的证据。另有3例患者尽管采取了机械和药物预防措施，但术后仍发生了深静脉血栓形成。我们已停止在单纯的下肢初次全关节置换术前进行双功超声检查。对于高危患者、有深静脉血栓形成或静脉炎综合征病史的患者以及先前接受过下肢大手术的患者，我们仍在术前进行双功超声检查。
