Endovascular stent placement is considered the preferred treatment for this condition. Guidelines increasingly support the use of so called covered stents (CS) in stead of bare stents (BMS) for this use but the level of evidence for this is limited. Using CS incur additional costs for healthcare short-term but may prevent recurrence of narrowing and symptoms postoperatively benefitting patients and healthcare.\n\nStudy Objective:\n\nTo evaluate the outcomes after stenting of mesenteric arteries using BMS or CS.\n\nStudy Outcome:\n\nPrimary stent patency 1 year after placement\n\nThe trial will also evaluate complications, how often stents need to be reoperated, Quality of Life (QoL) and reasons for subjects death\n\nMethod:\n\nThis is a so called prospective, randomized controlled trial comparing CS vs. BMS. This means that one patients have agrred to treatment they will be randomly selected for treatment with either CS or BMS . The stent metal structure is identical in the two implants and the only difference is the graft covering, making this study unique.\n\nThe study will also collect blood samples for a biobank that will be used to study markers of disease and how these effect treatment outcomes.\n\nAll patients referred to the Department of Vascular Surgery due to CMI are considered for inclusion if they havechronic symptoms consistent with CMI, significant stenosis or occlusion of the superior mesenteric artery and are \\> 18 years Subjects not able to provide informed consent or who have non atherosclerotic cause of CMI, signs of acute loss of blood flow to the intestines cannot participate. Previous stent treatment in the superior mesenteric artery, pregnancy, allergies to contrast or stent materials are also reasons for not being included in this trial.\n\nSide effects, risks and disadvantages for participants The risk for procedure-related complications is less than 5% and similar in both study groups. Most short-term complications are related to vascular access sites and consist of local bleeding and thrombosis. Other potential complications include impaired renal function due to contrast use, contrast allergy, arterial dissection and death.",[89,90,91,92,93,94,95,96,97,98],"Mesenteric Ischemia","Bowel; Ischemic","Superior Mesenteric Atherosclerosis","Mesenteric Artery Stenosis","Stent Restenosis","Stent Occlusion","Stent Thrombosis","Stent-Graft Stenosis","Stent-Graft Thrombosis","Stent-Graft Restenosis","2023-06-09",{"date":101,"type":102},"2023-06-12","ACTUAL",{"date":104,"type":83},"2023-06",{"date":106,"type":83},"2029-08",{"name":5,"class":6},1]
