Multi-detector computed tomography (MDCT) on admission. A and B. Transverse plane (A) and coronal plane (B) at the ilio-cava junction level. Left external iliac vein (lt EIV) branches off directly from the inferior vena cava. The left EIA is compressed by the abdominal aorta (*) with thrombus; C to E.
