ABSTRACT
Hereditary hemorrhagic telangiectasia also known as Osler-Weber-Rendu syndrome, is an disorder that causes abnormal blood vessel formation with bleeding. Inhibition of angiogenesis amelioretes bleeding complication. Anti-angiogenic agents such as bevacizumab, aflibercept, thalidomid, lenadomid and other new anti-angiogenic thyrosinkinase inhibitors, as well as sirolimus and takrolimus have emerged as a promising systemic or local therapy in reducing bleeding complications but are not curative. Other pharmacological agents include iron supplementation, antifibrinolytics and hormonal treatment. This review concentrates on new anti-agioproliferative drugs with effect in HHT- discusses the new biology of HHT, management issues that face the practising hematologist, and considerations of future directions in HHT treatment.

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, is an autosomal dominant disorder that causes abnormal blood vessel formation. Patients with HHT may have telangiectasias and later may develop arteriovenous malformations in various organs. Pacients suffer from many complications caused by the malformations and therefore by patients with HHT must by performed screening of this arteriovenous malformations. Optimal treatment of this malformations is best delivered throught a multidisciplinary approach. Farmacological treatment is described in next paper.
