Superior mesenteric artery thrombosis and small bowel necrosis: An uncommon thromboembolic manifestation in COVID-19 pneumonia.

Thromboembolism is a recognized complication in patients with COVID-19 infection. It is believed that coagulopathy results secondary to severe inflammatory response syndrome with release of cytokines, viral activation of coagulation cascade or viral related vasculitis. Both arterial and venous thromboembolic complications have been described, however venous thromboembolic complications are much far common. We present an uncommon thromboembolic complication of the superior mesenteric artery in a 49-year-old male with COVID-19 pneumonia. The patient also developed segmental infarct of his renal transplant. Patients with SARS-COV-2 infection should be closely evaluated and monitored for the development of thromboembolic complications. Prompt evaluation with CT angiography of suspected thromboembolism could help early diagnosis and treatment which can reflect better patients' outcomes.
