ABSTRACT
Crohn's disease (CD) is a type of inflammatory bowel disease that primarily affects the small intestine and colon. Patients with CD may develop extra-intestinal manifestations; however, vascular involvement has been rarely reported. Herein, we present the case of a patient with CD who developed multiple arterial complications, including lower extremity arterial occlusions and an abdominal aortic aneurysm (AAA). A 42-year-old man with CD presented with back pain. He also had a history of bilateral iliac artery occlusions that were refractory to revascularization procedures. Enhanced computed tomography revealed an irregularly shaped AAA with a maximum axial diameter of 72 × 52 mm. The patient underwent endovascular aneurysm repair (EVAR) for the AAA via the left axillary access, and the postoperative course was uneventful. At seven years postoperatively, significant shrinkage of the aneurysm was maintained, and his CD remained in remission. The present case suggests that patients with CD can develop AAA as a rare extra-intestinal manifestation. Significant aneurysm shrinkage was achieved following EVAR.
