Purpose:
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.
Methods:
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.
Results:
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).
Conclusions:
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.
