IntroductionRefractory cardiac arrest carries a poor prognosis. Extracorporeal cardiopulmonary resuscitation (ECPR) can be lifesaving but is associated with high morbidity and mortality. We report a likely underdiagnosed complication - non-occlusive mesenteric ischemia (NOMI) - following ECPR, emphasizing the diagnostic challenges and the role of early endoscopic evaluation and an interdisciplinary assessment of these patients.Case PresentationA 48-year-old man presented with ST-elevation myocardial infarction and developed refractory cardiac arrest due to ventricular fibrillation. ECPR was initiated, and extracorporeal membrane oxygenation (ECMO) flow was achieved after 77 min of cardiopulmonary resuscitation. Early after arrest, the patient passed bloody stool, raising suspicion of mesenteric ischemia. Computed tomography was inconclusive, but colonoscopy revealed ischemic bowel injury. Given the fatal potential of untreated NOMI, prompt colectomy was performed. The patient stabilized postoperatively, recovered progressively, and was discharged from the intensive care unit in good condition after 14 days.ConclusionNOMI should be considered in ECPR patients presenting with gastrointestinal bleeding, even when cross-sectional imaging findings are inconclusive. Early colonoscopy enables timely diagnosis and surgical intervention, potentially improving survival in this high-risk setting.
