Sonographic Evaluation of Budd-Chiari Syndrome With Intracaval Stent

Budd-Chiari syndrome (BCS) with an intracaval stent is a rare presentation. In most Western patients with BCS, it is predominantly the hepatic veins that are involved, not the inferior vena cava (IVC). In the case presented, the patient had antiphospholipid syndrome with BCS that involved the IVC and required an intracaval stent. Presented with the case study are scanning techniques for BCS and the IVC to help sonographers evaluate the normal and abnormal anatomy and hemodynamics of this system.
