Impedance plethysmography. A screening procedure to detect deep-vein thrombosis.
Impedance plethysmography has great potential in the non-invasive detection of dangerous iliofemoral thrombosis. It was used to examine 198 patients undergoing total hip replacement for evidence of proximal venous segment thrombosis. There were 13 abnormal results, and subsequent venography in 12 of these revealed a false-positive rate of 4.0%; there was one false-negative result giving a sensi...
متن کاملCompression ultrasonography for diagnostic management of patients with clinically suspected deep vein thrombosis: prospective cohort study.
OBJECTIVE To evaluate the safety of withholding anticoagulant treatment from patients with clinically suspected deep vein thrombosis but normal findings on compression ultrasonography. DESIGN Compression ultrasonography was done with a simplified diagnostic procedure limited to the common femoral vein in the groin and the popliteal vein extending down to the trifurcation of the calf veins. Pa...
متن کاملDuplex ultrasound in the emergency department for the diagnostic management of clinically suspected deep vein thrombosis.
OBJECTIVES To evaluate the accuracy and safety of an emergency duplex ultrasound (EDUS) evaluation performed by emergency physicians in the emergency department. METHODS Consecutive adult patients suspected of having their first episode of deep vein thrombosis (DVT) presenting to the emergency department were included in the study. All examinations were performed by emergency physicians train...
متن کاملSimplification of the diagnostic management of suspected deep vein thrombosis.
BACKGROUND The standard diagnostic approach in patients with suspected deep vein thrombosis is to repeat the compression ultrasonography after 1 week in all patients with an initial normal result. We hypothesized that a normal finding of a D-dimer assay safely obviates the need for repeated ultrasonography. In addition, we evaluated the potential value of a pretest probability assessment for th...
متن کاملDiagnostic approaches to suspected deep vein thrombosis and pulmonary embolism.
The present paper aims at reviewing our present knowledge on the diagnosis of deep vein thrombosis and pulmonary embolism with a particular emphasis on clinically suspected outpatients. The various contemporary diagnostic tools (including clinical probability assessment, fibrin D-Dimer measurement, venous compression ultrasonography, ventilation/perfusion lung scintigraphy, helical CT scan, and...
