Symptomatic Mesenteric Atherosclerotic Disease-Lessons Learned from the Diagnostic Workup

This study aims to analyze the diagnostic workup in patients referred for endovascular mesenteric revascularization for symptomatic mesenteric atherosclerotic disease. Fifty-five patients were identified between 2006 and 2011. Median follow-up time was 24 months. Median age was 71 years, 67 % were women. Forty patients had acute on chronic mesenteric ischemia, eight had acute mesenteric ischemia, and seven had chronic mesenteric ischemia. Other manifestations of atherosclerotic disease were present in 71 %. Body mass index (BMI) < 20 kg/m(2) was found in 37 %. Endoscopy diagnosed duodenitis (38 %; 13/34) and colitis in the right colon (57 %;12/21). All ulcers tested for Helicobacter pylori were negative (n = 17). Patients received proton pump inhibitor, antibiotic, and cortisone therapy during diagnostic workup in 73, 42, and 29 % of the cases, respectively. Previous hospitalization for the same complaints had occurred in 78 %. CT angiography showed occlusion (n = 30) and high-grade stenosis (n = 25) of the superior mesenteric artery (SMA). Forty-eight patients were treated with stenting of the SMA. The BMI increased in both women (p = 0.001) and men (p = 0.03) after endovascular therapy. The in-hospital mortality rate was 18 %. Patients with abdominal pain, known atherosclerotic disease, right-sided colitis or H. pylori-negative duodenitis should undergo CT angiography immediately to be able to identify symptomatic mesenteric atherosclerotic disease.
