Superior mesenteric artery endarterectomy for chronic mesenteric ischemia: A viable alternative in poor candidates for endovascular interventions

Abstract

Background Chronic mesenteric ischemia can be treated with either endovascular approaches or surgical revascularization. Recent data suggest that surgery leads to more durable symptom relief with similar long-term survival compared to transcatheter angioplasty. Splanchnic vessel endarterectomy has been shown to lead to longer freedom from recurrence compared to the more commonly used surgical bypass procedure. Methods We retrospectively reviewed the medical records of patients with chronic mesenteric ischemia who were considered poor candidates for endovascular repair and therefore underwent superior mesenteric artery endarterectomy in our institution. Study period was April 2016 to April 2018. Results A 73-year-old female and a 69-year-old male patient fulfilled our inclusion criteria. Extensive stenosis of the celiac axis and the superior mesenteric artery was found in both patients. superior mesenteric artery endarterectomy was performed in both cases. Endarterectomy was closed using a polytetrafluoroethylene patch. Both patients are alive and symptom-free at one year postoperatively with no signs of restenosis. Conclusions Our institutional outcomes are in line with recent literature supporting superior mesenteric artery endarterectomy as a viable alternative to surgical bypass in patients with chronic mesenteric ischemia who are suboptimal candidates for endovascular angioplasty and stenting.
