Abstract
Liver transplantation provides definitive treatment to address acute or chronic end-stage
liver disease and its complications. Hepatic venous outflow obstruction is an infrequent
complication of liver transplantation that affects graft survival by compromising
outflow via transplant hepatic veins or inferior vena cava. It can occur in the early
postoperative phase or in a delayed manner, resulting in venous congestion, graft
dysfunction, graft failure, and death. This article addresses the pathophysiology
of venous outflow obstruction as it relates to different surgical techniques and patient
populations, the noninvasive tools for diagnosis, and the endovascular options for
treatment along with their safety, efficacy, and durability.
