Objectives: To evaluate technical success rate and clinical outcome of patients with acute embolic superior mesenteric artery (SMA) occlusion who were treated with primary percutaneous revascularization.Methods: At three medical centers the radiological information system databases were used to identify all patients in whom primary percutaneous revascularization for the treatment of acute embolic SMA occlusion was attempted between 2001 and 2010. Percutaneous treatment was performed in 15 patients (median age 80 years, range 49-88 years). These patients represent the study population. Eleven patients reported abdominal pain. Five patients exhibited peritoneal signs. Revascularization was defined as complete technical success if (1) patency of the SMA with residual stenosis of not more than 30% in diameter and (2) sufficient perfusion of the entire bowel were obtained.Results: Complete technical success was achieved in eleven patients. After percutaneous revascularization laparotomy was performed in six patients and in three of them bowel resection was carried out (length of resected segments 20-80 cm). The 30-day mortality was 33% (five of 15 patients). None of the surviving patients exhibited short-bowel syndrome.Conclusions: Primary percutaneous aspiration and thrombolysis constitutes a promising alternative to surgical revascularization in selected patients with acute embolic SMA occlusion.

Colonography based on magnetic resonance imaging (MRI) appears to be a promising technique for polyp assessment in the colon. Several studies have evaluated this method for colonic assessment in patients with inflammatory bowel disease. We briefly review different methodologies such as dark lumen and bright lumen techniques for abdominal MRI. In addition, recently published studies concerning the sensitivity and accuracy in detecting inflammatory bowel changes in inflammatory bowel disease using MRI are discussed. [ABSTRACT FROM AUTHOR]
