FIGURE 1
The Gradman‐Steinberg classification of inferior vena cava aneurysms. (A) Type‐1 IVC aneurysms are in the suprahepatic cava without venous interruption. (B) Type‐2 are those associated with anomalies to the IVC. It is thought that these interruptions could lead to an increase in cava pressures, contributing to the formation of an aneurysm. (C) Type‐3 are in the infrarenal IVC and occur without vascular anomaly. (D) Type‐4 represent miscellaneous aneurysms that do not fit within the previous categories. Depicted here a left sided IVC with associated aneurysm of the iliac vein. Figure adapted from Gradman and Steinberg 1993 [3].
FIGURE 2
FIGURE 2
CT on admission coronal (A) and sagittal (B) non‐contrast computed tomography images demonstrate a suprahepatic aneurysm measuring 45 × 36 mm (red arrow) with involvement of the hepatic veins (white arrowhead). There is no involvement of the right atrium (blue arrowhead), nor other abnormalities of the vena cava or evidence of atrio‐caval reflux or thrombus.
