title: Diagnosis of deep venous thrombosis in obstetrics and gynecology by impedance phlebography.
abstract: The accurate diagnosis of deep venous thrombosis is fundamental in reducing the morbidity and mortality from thromboembolism in obstetrics and gynecology. This is the first report of the use of a noninvasive diagnostic technique, occlusive cuff impedance phlebography (IPG), on an obstetric and gynecologic service. One hundred sixteen patients were examined by IPG with an overall diagnostic accuracy of 95.6% (sensitivity, 87.5%; specificity, 93.8%). Ninety-one patients had symptoms suggestive of deep venous thrombosis, but this diagnosis was confirmed in only 26.3%. The use of IPG to screen high-risk patients prospectively and evaluate patients with pulmonary emboli is discussed. IPG is ideally suited as a diagnostic method in obstetrics and gynecology because it is accurate, noninvasive, and nonradiologic, and it may be performed at the patient's bedside.
