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 venovenous extracorporeal membrane oxygenation (VV-ECMO) were started. On the second day in ICU, he had a septic shock due to ventilator-associated pneumonia. Five days later, the patient had new-onset melena and laboratory data showed a hemoglobin level of 7.8g/dL.
