BackgroundSpontaneous isolated dissection of the superior mesenteric artery (SIDSMA) occurs when a tear in the inner layer of the superior mesenteric artery (SMA) allows blood to flow between the layers of the SMA, forcing the layers apart, and creating two lumens. Abdominal pain is the most prevalent clinical manifestation. Other people may have no symptoms or experience nausea, vomiting, diarrhea, or blood in their stools. For people with SIDSMA who are not suspected of intestinal necrosis or intra-abdominal bleeding, medical treatment and endovascular therapy are the main treatment options. There is no consensus on the optimum first-line management strategy.ObjectivesTo evaluate the benefits and harms of endovascular therapy versus medical treatment for spontaneous isolated dissection of the superior mesenteric artery (SIDSMA).Search MethodsWe used standard, extensive Cochrane search methods. The latest search date was 3 August 2021.Selection CriteriaWe planned to include all randomized controlled trials (RCTs) which compared endovascular therapy and medical treatments for SIDSMA. We planned to exclude studies where participants were treated with open surgery.Data Collection And AnalysisWe used standard Cochrane methods. Our primary outcomes were endovascular intervention rate and recurrent abdominal pain. Our secondary outcomes were open surgery rate, remodeling rate of SMA, new aneurysm formation of SMA, SMA occlusion, new dissection of SMA, death, symptom relief rate and complications of endovascular therapy. We planned to use GRADE to assess certainty of evidence for each outcome.Main ResultsWe did not identify any RCTs to include in any analysis. We were not able to include any RCTs that compared endovascular therapy versus medical treatment in people with SIDSMA. High-quality RCTs that evaluate the benefits and harms of these interventions are needed to help determine the optimal strategy for managing SIDSMA.Copyright © 2022 The Cochrane Collaboration.
