Gastroduodenal ischemia in a patient with severe SARS-CoV-2 infection

A 54-year-old male with a past medical history of hypertension, dyslipidemia, obesity, and diastolic heart failure, was admitted due to COVID-19 pneumonia. Respiratory failure gradually deteriorated and the patient was transferred to the intensive care unit (ICU), where mechanical ventilation and veno-venous extracorporeal membrane oxygenation (VV-ECMO) were started. On the second day in the ICU, he went into septic shock due to ventilator-associated pneumonia. Five days later, the patient had new-onset melena and laboratory data showed a hemoglobin level of 7.8 g/dL. He required blood transfusions and vasopressor requirements increased.
