Liver graft outcomes from donors with vaccine induced thrombosis and thrombocytopenia (VITT): United Kingdom multicenter experience.

Vaccine-induced immune thrombosis and thrombocytopenia (VITT) syndrome is a new entity, characterised by severe thrombocytopenia and multiple sites of thrombosis1 . The presumed mechanism is driven by anti-platelet factor 4 (PF4) antibodies causing platelet activation1 . Donors with VITT syndrome have a particular relevance for liver transplantation (LT), due to the associated risk of passenger lymphocyte syndrome, and a predisposition for porto-mesenteric or hepatic vein thrombosis2 .
