This study assesses the sonographic incidence of deep venous thrombosis (DVT) contralateral to and the venographic incidence ipsilateral to hip or knee replacement surgery and the role of sonography in routine surveillance.
We prospectively evaluated 178 consecutive patients with sonography of the femoropopliteal venous systems of the contralateral lower extremity and venography of the ipsilateral lower extremity on days 3 and 4, respectively, after total hip or knee replacement surgery.
No cases of acute DVT and only 1 case of chronic DVT isolated to the popliteal system were identified by sonography in the contralateral extremity. In the ipsilateral extremity, venography identified 26 patients with acute DVT (3 femoropopliteal, 21 calf, and 2 concurrent femoropopliteal and calf).
Routine sonographic evaluation of the lower extremity contralateral to hip or knee replacement surgery is not cost-effective because of the extremely low incidence of detectable acute thrombus.
本研究评估髋关节或膝关节置换手术对侧深静脉血栓形成（DVT）的超声发生率以及同侧静脉造影发生率，以及超声检查在常规监测中的作用。
我们前瞻性地评估了178例连续患者，分别在全髋关节或膝关节置换手术后第3天和第4天对其对侧下肢的股腘静脉系统进行超声检查，并对同侧下肢进行静脉造影。
对侧肢体超声检查未发现急性DVT病例，仅发现1例孤立于腘静脉系统的慢性DVT病例。在同侧肢体中，静脉造影发现26例急性DVT患者（3例股腘静脉，21例小腿，2例股腘静脉和小腿同时存在）。
由于可检测到的急性血栓发生率极低，对髋关节或膝关节置换手术对侧下肢进行常规超声评估不具有成本效益。
