We reviewed the clinical manifestations of mesenteric vasculitis due to giant cell arteritis (GCA) and considered features of the mesenteric anatomy in relationship to disease expression. We compiled and reviewed a case series by systematic identification of patients previously reported in the English-language literature to have mesenteric involvement from known GCA. Included in the analysis was a detailed case review of a patient with GCA and small bowel infarction seen at our institution. Twelve patients were identified with mesenteric ischemia attributed to GCA. Concomitant cranial and abdominal symptoms were present in 7 of the 12 patients, and cranial symptoms were absent in 5 patients who presented with abdominal complaints. The abdominal symptoms fell within a spectrum ranging from chronic postprandial symptoms to acute abdominal pain. Survival was observed in only 6 of the 12 cases, 3 of whom required bowel resection and were treated with high-dose corticosteroids. Review of the anatomic features of the specialized splanchnic circulation reveals an extensive collateral network that may protect against early disease expression from ischemia, despite mesenteric arteritic involvement. Mesenteric vasculitis resulting in small bowel infarction has only rarely been described in GCA but represents a serious and potentially treatable complication. We propose an explanation, based on mesenteric vascular anatomy, for the infrequency of symptomatic expression of this entity and suggest that occult mesenteric GCA may be present far more often than recognized.

Mesenteric vasculitis secondary to polyarteritis nodosa represents an atypical but potentially life-threatening cause of bowel ischemia and acute abdomen. The patient presented with severe abdominal pain of recent onset, pitting edema of the legs, renal failure and bowel wall thickening suggestive of mesenteric ischemia on CT scan. Early laparoscopy allowed to rule out proximal bowel necrosis and resection was avoided. The patient was successfully managed with corticosteroid therapy and repeated hemodialysis sessions.

Mesenteric vasculitis and resultant bowel ischemia is rare but serious complication of autoimmune disorders. Early detection and treatment is the key to avoid potentially fatal outcomes of bowel perforation and peritonitis. In this series, we present patients presenting with acute abdominal pain and having CT imaging features of bowel ischemia who responded well to immunosuppressive therapy. The aim of this work is to familiarize health professionals with possibility and imaging features of mesenteric vasculitis.
