Computed tomography showing bilateral common iliac artery aneurysms and a dilated vena cava. Postoperatively, we could detect the enhanced paravertebral vein (arrow). The non-enhanced vena cava indicated an arteriovenous fistula located distal to the vena cava

CT showed bilateral common iliac aneurysms (Fig. 1), and the internal iliac artery had a maximum diameter of 8 cm (Fig. 2). Postoperatively, we detected the enhanced left paravertebral vein (Fig. 1) and the left ascending lumbar vein (Fig. 5) on arterial-phase CT, and these were the only indications of the presence of an AVF on CT.
Schematic illustration of blood pressure shifts on arterial pressure wave. The arterial wave form deteriorates on diastolic runoff to achieve a far lower end-diastolic pressure. Following the falling, the next peak systolic pressure is measured lower than the latter. These shifts occur repeatedly, and the arterial wave form returns gradually to the former state
