Both DVT and PE are often silent and difficult to detect by clinical examination. The use of a number of diagnostic tests, such as fibrinogen uptake, Doppler ultrasound, impedance plethysmography, venography, ventilation-perfusion scans, and pulmonary angiography, has resulted in the identification of several groups of patients at high risk of developing venous thromboembolic disease. Patients undergoing various types of surgery—general, orthopedic, gynecologic-obstetric, urologic, and neurosurgical—are at high risk for developing DVT and PE.
