Updates to Study Attributes
There is a large infrarenal fusiform abdominal aortic aneurysm, this demonstrates maximal transverse dimensions of 10.3 cm and AP dimensions of 9.8 cm. The craniocaudal extent is 15.6cm.6 cm with the superior extent commencing at approximately the level of the renal arteries and the distal portion extending to the aortic bifurcation. During the arterial and portal venous phases, appearances are in keeping with a contained rupture at the right posterolateral aspect of the aneurysm. There is premature contrast opacification of the adjacent IVC and common iliac veins, in keeping with an aortocaval fistula. This accounts for the poor contrast opacification of the iliac arteries on the arterial phase. There is no evidence of active haemorrhage into the retroperitoneum.
