Overview
Compression ultrasonography, also known as a Doppler study of the legs, or lower extremity noninvasive studies (LENIS) is used to evaluate a patient for the presence of deep venous thrombosis (DVT) in the lower extremities, which can lead to the development of a pulmonary embolism. The presence of a DVT shown by ultrasonography is enough to warrant anticoagulation without a V/Q or spiral CT scans. The decision to anticoagulant patient with a positive compression ultrasound is due to the strong association between deep vein thrombosis and subsequent pulmonary embolism. Compression ultrasonography is not the routine initial method of evaluation in a suspected PE during pregnancy unless the patient has coexisting symptoms and signs of DVT.[1] In case the compression ultrasound is negative for DVT and there is persistent clinical suspicion of PE, the negative ultrasound does not rule out PE and additional imaging tests are required.[1]
