Orthotopic Liver Transplant (OLT) was traditionally performed using conventional caval reconstruction with end-to-end anastomosis. In recent years however, the piggyback technique (PB) with preservation of the recipient retrohepatic IVC and side-to-side anastomosis of the donor IVC to a cuff fashioned from the recipient hepatic veins, has gained popularity. The purpose of this study is to report the variety of MRI appearances of the donor IVC stump produced as a result of this new technique, which may cause confusion in the uninformed reader.
