摘要: Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, is an hereditary disorder that results in fibrovascular dysplasia with the development of telangiectasias and arteriovenous malformations. It predominantly involves skin, mucous membranes, viscera, lungs, brain. shows great genetic heterogeneity, its phenotypes have been classified based on recently identified mutated genes: endoglin (HHT-1) activin-like kinase receptor-1 (HHT-2). Other families phenotypic HHT do not bear these mutations; therefore, other genes are probably involved well. Liver involvement reported up to 30% persons affected by HHT. Large malformations liver can lead significant complications, including high-output congestive heart failure, portal hypertension, hepatic encephalopathy, biliary ischemia, failure. Embolization large remains controversial; however, transplantation successfully eradicate complications.
