Dec 18, 2024 · Enhanced CT shows the location and severity of the superior vena cava obstruction, superimposed thrombosis, a mediastinal mass or lymphadenopathy, collateral vessels, and associated lung masses. A focal hepatic hot spot sign may be visible.

Sep 15, 2021 · The superior vena cava (SVC) is a large valveless venous channel formed by the union of the brachiocephalic veins. It receives blood from the upper half of the body (except the heart) and returns it to the right atrium.
