ABSTRACT
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder
that can involve the liver diffusely in the form of vascular malformations ranging
from small telangiectases to discrete arteriovenous malformations. Anatomically, three
different patterns of abnormal vascular communications can occur in liver: portal
vein to hepatic vein (portovenous), hepatic artery to hepatic vein (arteriovenous)
and hepatic artery to portal vein (arterioportal), with the most common being arteriovenous.
Only 5 to 8% of patients with these vascular malformations are symptomatic. When symptomatic,
patients present with high-output cardiac failure, biliary ischemia (which, when severe,
can progress to biliary and hepatic necrosis and lead to acute liver failure), or
portal hypertension. Other less common presentations include portosystemic encephalopathy
and abdominal angina. Diagnosis is confirmed by Doppler ultrasonography or multidetector
computed tomography. The hallmark findings are intrahepatic hypervascularization and
an enlarged common hepatic artery. Focal nodular hyperplasia and nodular regenerative
hyperplasia are common findings. Symptomatic patients are treated with intensive medical
treatment aimed at the predominant clinical presentation. Patients who fail aggressive
medical therapy and those with acute biliary/hepatic necrosis should be considered
for liver transplantation.
