The role of endovascular therapy in acute mesenteric ischemia
Background Endovascular therapy, including aspiration thrombectomy and local thrombolytic therapy, often associated with angioplasty and stent placement, has been described in the literature. The purpose of this study was to review case series of patients with acute mesenteric ischemia treated with endovascular therapy and evaluate their outcomes.
Methods An online review using PubMed was carried out to identify all English articles about this topic in the time interval from 2005 to 2016. The following variables were extracted: number of patients, cause of occlusion, symptoms, arteries involved, number of sessions of treatment, technical success, clinical success, recurrence rate, complications, mortality rate, number of patients who underwent diagnostic laparoscopy or surgical resection of ischemic bowel.
Results Eighteen papers met the inclusion criteria and were included. Among the patients with arterial mesenteric ischemia treated with endovascular approach, the technical success rate was high (up to 100%) and data regarding clinical success are encouraging, even though they are few and heterogeneous. Technical success rate and clinical success of patients with acute venous mesenteric ischemia approached with endovascular treatment was 74-100% and 87.5-100% respectively.
Conclusions Current advances in endovascular therapies have made these treatments feasible for mesenteric ischemia.
