[Acute venous mesenteric ischemia in a young COVID-19 positive subject: a case report].

Acute mesenteric ischemia (AMI) is due to a sudden decrease or interruption of mesenteric blood flow resulting in inadequate blood supply to the gastrointestinal tract. This causes ischemic and inflammatory lesions often progressing to necrosis in the absence of appropriate treatment. Vascular insufficiency may arise as a result of embolism or arterial thrombosis or venous thrombosis. We here report a rare case of mesenteric venous ischemia caused by coronavirus disease 2019 (COVID-19) in a 33-year-old man in whom diagnosis was based on ultrasound and, in particular, on computed tomography (CT).
