Osler-Weber-Rendu syndrome

  • Alternative Names

    Hereditary hemorrhagic telangiectasia; HHT


    Treatments include:

    • Surgery to treat bleeding in some areas
    • Electrocautery or laser surgery to treat frequent or heavy nosebleeds
    • Endovascular embolization to treat abnormal blood vessels in the brain and other parts of the body

    Some patients respond to estrogen therapy, which can reduce bleeding episodes. Avoid taking blood-thinning medications.

    Some patients may need to take antibiotics before having dental work or surgery. Ask your doctor what precautions you should take.
