Exertional Abdominal Pain as a Rare Presenting Manifestation of Chronic Mesenteric Ischemia from a Single Mesenteric Vessel Stenosis.

We present an atypical manifestation of chronic mesenteric ischemia in a patient with progressively worsening exertional abdominal pain. Imaging modalities revealed significant isolated stenosis of superior mesenteric artery (SMA). Successful angioplasty and stenting of SMA relieved patient's symptoms, thereby confirming the diagnosis of chronic mesenteric ischemia. Exertional abdominal pain may be a unique manifestation of this disease, but when it presents, clinicians should have acute clinical awareness of this diagnosis.
