Critical intestinal ischaemia in a patient with patent mesenteric vasculature.

We present a case of a 62-year-old man with known coeliac disease who was admitted for investigation of abdominal pain and weight loss. He underwent multiple biochemical, haematological, radiological and endoscopic investigations (which were all normal) and also had a normal laparoscopy. Abdominal computerized tomography angiography, however, suggested significant mesenteric stenosis. Mesenteric angiography confirmed superior mesenteric artery stenosis and reproduced the patient's abdominal pain when the catheter crossed the lesion. Balloon angioplasty successfully dilated the stenosis, and since then the patient has gained 19 kg in weight (returning his body mass index from 17 to 23) and has been symptom free. Symptomatic single vessel mesenteric ischaemia (other than coeliac artery stenosis in median arcuate syndrome) is not previously well described. The symptom reproduction on catheterization highlights how useful angiography can be in diagnosis of disease significance. Symptom resolution after angioplasty demonstrated clearly how even single vessel disease can cause significant compromise to the mesenteric circulation.
