Aim:
To evaluate the indications, timing and results of liver transplantation in patients affected by hereditary hemorrhagic telangiectasia (HHT), by undertaking a systematic review of the current literature.
Methods:
Electronic bibliographical databases were searched on MEDLINE and Pubmed according to the PRISMA criteria. A total of 58 articles were initially found, 11 have been excluded because of single center series later included in the European Liver transplant Registry (ELTR), already reported in this study. Thirty-eight articles have been excluded because they did not report specifically new cases of liver transplantation for hereditary hemorrhagic telangiectasia. Finally 9 articles were included in the analysis.
Results:
A total of 56 patients who underwent liver transplantation for HHT are present in the English literature. One additional patient is presented in this article, for a total of 57 patients worldwide. To date, the most consistent published series is the one of the ELTR, including patients from 15 liver transplantation centers in the period 1985-2003 with a mean follow-up of 69 months. Ten-year patient and graft survival is 82.5% CONCLUSION: Liver transplantation should be considered as a radical but definitive treatment option in patients affected by HHT with liver or cardiac involvement not responsive to medical treatment.
