Vaccine-induced Thrombotic Thrombocytopenia and Graft Thrombosis in a Renal Transplant Recipient

Abstract

The use of COVID-19 vaccines has been associated with sporadic reports of thrombosis with thrombocytopenia, a complication referred to as vaccine-induced immune thrombotic thrombocytopenia (VITT). Early recognition of this entity before the occurrence of thrombosis detected by imaging is termed as a pre-VITT syndrome. Thrombosis has been reported to occur in the cerebral venous system, splanchnic veins as well as arteries to the lower limbs. We present the case of a young renal transplant recipient who presented with VITT following ChAdOx1 nCoV-19 (Covishield) vaccination; in this case, thrombosis occurred in the intrarenal arteries of the graft kidney.
