A simultaneous superior mesenteric arterial and venous thrombosis in an elderly woman with a previous COVID-19 pneumonia: A suggestive case report diagnosed at computed tomography angiography.

Superior mesenteric artery (SMA) and superior mesenteric vein (SMV) thrombotic occlusion is a rare but potentially fatal condition. Though isolated mesenteric arterial occlusion associated with COVID-19 has been reported in literature, combined superior mesenteric arterial and venous thrombosis is very rare. We report the case of an 88-years-old woman with a combined superior mesenteric arterial and venous thrombotic occlusion with a previous COVID-19 pneumonia of about 15 days before, diagnosed at computed tomography angiography (CTA) scan. CTA had an important key-role for the diagnosis and evaluation of the severity of the mesenteric venous and arterious thrombosis.
