The article presents a case report of a 53-year-old man, who underwent abdominal surgery for the ischemic vascular necrosis of the small bowel and right colon of the embolic aetiology and who has had several serious comorbidities. Resection of the major part of the small bowel and right hemicolectomy with high jejunostomy and transversostomy was performed. Not only has the patient very well tolerated the first surgery, but he tolerated also the other one with recovery of passage continuity. The other surgery was necessary due to mycotic infection in the right atrium (vegetations at the heart pacing electrode). After 5 months the patient died because of generalisation of mycotic infection. The problem of mesenteric vascular occlusions is discussed.

        Key words: mesenteric vascular occlusion, mesenteric superior artery, embolism.
