Several cases of deep venous thrombosis in people who had recently received Vaxzevria (previously known as COVID-19 Vaccine AstraZeneca) have recently been reported, mainly presenting as cerebral vein/cerebral venous sinus thrombosis. This syndrome has been termed “vaccine-induced immune thrombotic thrombocytopenia (VITT)”. Acute spleno-porto-mesenteric vein thrombosis is an uncommon but serious condition with potential sequelae, such as small-bowel gangrene and end-stage liver failure. We describe a case of concomitant thrombosis of portal, superior mesenteric and splenic veins in a young female patient with no other risk factors who received Vaxzevria (previously ChAdOx1 nCoV-19 vaccine, AstraZeneca) 17 days before. The diagnostic workup and the successful endovascular treatment and systemic anticoagulation management is reported.
