Visceral arterial occlusions

Case contributed by Roberto Schubert
Diagnosis certain

Presentation

Incidental finding in a patient with peripheral arterial occlusive disease who underwent a bolus-chase MR angiography.

Patient Data

Age: 70
Gender: Female
mri

Non-visualization of the celiac trunk and the superior mesenteric artery immediately distal to their respective origins. Ectatic and elongated inferior mesenteric artery. Low-grade stenosis of the left common iliac artery. The patient also had occlusions of both superficial femoral and anterior tibial ateries (not shown).

Case Discussion

The viscera are most probably supplied by the inferior mesenteric artery via the arc of Riolan, which could not be depicted in full due to peristalsis artifacts. Abdominal angina was not present in this case.
