Abstract
Liver transplant (LT) recipients are a challenging patient population when presenting
with graft dysfunction or sequelae of portal hypertension. When no medical causes
for graft dysfunction are found, a hemodynamically significant vascular lesion is
suspected. Although rare, a variety of diseases may arise involving the portal system,
which inhibit flow and graft function. Herein, we present a review of portal venous
interventions performed in the LT setting, with focus on imaging diagnosis, endovascular
treatment techniques, and outcomes. Entities addressed include portal venous stenosis,
portal venous thrombosis, and recurrent fibrosis/cirrhosis with sequelae of portal
hypertension.
