Objectives: After studying the article entitled “Differential Diagnosis of an Inferior Vena Cava Thrombosis/Hepatic Cyst Using an Abdominal Sonogram, Echocardiogram, Venography, and Computed Tomography Angiogram,” you will be able to
Evaluate the complementary roles of duplex sonography with other imaging modalities.
Describe the sonographic features of hepatic cysts.
Use appropriate sonographic windows for evaluation of the inferior vena cava.
When using the subcostal window to image the inferior vena cava, the patient should be _________. Prone and using a Valsalva maneuver Supine and using a valsalva maneuver Prone with a relaxed abdomen Supine with a relaxed abdomen
Reports in the literature suggest that inferior vena cava thrombus secondary to extrinsic compression occurs in approximately _______ percent of cases. 5-10 15-20 20-25 30-35
Echocardiography can be helpful in evaluating lesions of the inferior vena cava by measuring what? Aortic valve pressure gradients Left ventricular diastolic function Right heart hemodynamics Aortic arch velocities
Flow disturbances associated with extrinsic inferior vena cava compression are best determined by which method? Computed tomography Venography Spectral Doppler B-mode imaging of the narrowing
The spectral Doppler study of the inferior vena cava for the case presented showed _________. Elevated velocities with flow turbulence Normal laminar flow patterns Normal velocities with associated flow turbulence Mildly elevated velocities with laminar flow patterns
