Primary Endovascular Intervention for Acute Mesenteric Ischemia Performed by Interventional Cardiologists - A Single Center Experience.

The current standard care for acute mesenteric ischemia (AMEI) involves urgent revascularization and resection of the necrotic bowel. Since 2012, we have used an AMEI protocol of our own design, which focused on early treatment and allowed interventional cardiologists to become involved when interventional radiologist was not available. A total of 8 patients were treated, and two interventional cardiologists performed all the stenting procedures. The procedure success rate was 100% in patients with non-calcified lesions (6/8). The 30-day survival rate was 100% in patients with angiographic success, and was 0% in patients with failed procedure. In two patients with total occlusion of the superior mesenteric artery, laparotomy was avoided when interventions were successful and completed within six hours of protocol activation. Four surviving patients were discharged after short intensive care unit stays (less than 48 hours); these patients returned to and remained at home throughout their 90-day follow-up. The overall procedure success rate and 30-day survival rate were both 75%. There was no access site or intervention-related complications. Using our protocol, we believe that primary endovascular treatment for AMEI is feasible. In geographic regions where healthcare resources are lacking, a time-efficient strategy adopted by interventional cardiologists should be considered for the purpose of saving lives and possibly even avoiding open laparotomy.
