Abdominal aortic interposition tube graft and aneurysm thrombosis

Case contributed by Dr Roberto Pais

Presentation

Paraplegic patient with previous aorto-aortic interposition surgery to an abdominal aortic aneurysm.

Patient Data

Age: 55 years
Gender: Male

Right below the renal arteries root, there is a suggestive aspect of contrast progression interruption. Aneurysmal dilation from the downstream segment to the iliac bifurcation with 10 x 5.2 x 4.6cm.

The aneurysmatic segment, where the aorto-aortic interposition tube graft is localized, shows an heterogeneous density with some predominantly peripheral calcifications.

Distally there is contrast opacification in the distal segment of the primitive iliac arteries and proximal femoral vessels.

Case Discussion

This case demonstrates a severe abdominal aortic arterial flow interruption due, most likely, to an infra-renal anastomotic thrombosed aneurysm. 

The pelvic and inferior limbs circulation is still apparently patent due to collateral circulation through the superior mesenteric artery.
