Reperfusion injury on computed tomography following endovascular revascularization of acute mesenteric ischemia: prevalence, risk factors, and patient outcome

Abstract

Key points Reperfusion injury of the bowel occurred in 44% of patients with acute mesenteric ischemia treated by endovascular revascularization. A decreased bowel enhancement on initial CT (HR = 8.2), an occlusion of the superior mesenteric artery (HR = 7.0), an embolic cause (HR = 7.4), and higher initial serum lactate level (HR = 1.4) were identified as predictors of reperfusion injury. Bowel wall hypoattenuation, hyperenhancement of the mucosa, and increase in CRP levels after revascularization were key diagnostic features of reperfusion injury.
