Prospective screening for deep vein thrombosis in high risk patients.
In 257 patients undergoing total hip replacement, gastric bypass for morbid obesity, major abdominal surgery, and major leg amputation, Doppler ultrasonic screening revealed only five instances of deep vein thrombosis. The present study suggests that Doppler screening of high risk patients is a useful alternative to routine anticoagulant prophylaxis of venous thromboembolic disease.
