The efficacy of anti-VEGF treatments such as Bevacizumab in cases of HHT can be considered because of the molecular mechanisms implied in angiogenesis and HHT, as well as the mechanisms of action of this type of treatment. Two articles that have recently reported spectacular improvement thanks to Bevacizumab in patients with HHT complicated with severe liver involvement and cardiac effects support us in this sense.
Up to now, the only treatment recommended in the severe hepatic forms of HHT is a liver transplant, the disadvantages of which are both multiple and well known: long waiting lists, surgical morbidity and mortality, immunosuppressive treatment for life. Furthermore, treatment with Bevacizumab is not a contraindication, should the drug be ineffective, for a subsequent liver transplant if necessary.

Study using a Gehan design, 7 patients will be included in the first phase and 18 additional patients will enter the second phase.
5 mg / kg every 14 days with a total of 6 injections.A two-phase Gehan method will be used with a first phase designed to eliminate a non effective treatment quickly and a second phase allowing assessment of efficacy.
