Fig. 1B. —52-year-old man with hypotension at time of CT scan and "flat cava" sign at first three of four levels. Patient had severe colitis, which led to sepsis, hypovolemia, and hypotension (blood pressure, 100/50 mm Hg) and was being administered dopamine to maintain blood pressure. Total craniocaudal extent of flattened inferior vena cava was approximately 10 cm. CT scan at level just below renal veins shows flattened inferior vena cava (arrow). Ratio of maximal transverse (2.7-cm) to anteroposterior (0.6-cm) dimension of cava is 4.5:1.
