Image Acquisition Method for the Sonographic Assessment of the Inferior Vena Cava
Published on: January 13, 2023
Abstract:
A case of anomalous inferior vena cava with azygos continuation first diagnosed by computed tomography (CT) and later confirmed by venography is presented. In addition to identifying the dilated azygos vein in the chest, CT can determine the direction of flow in the vein by means of a bolus contrast medium injection. Once this is established, a search for the etiology of the dilated vein can be directed to the appropriate anatomic area.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
