Hereditary hemorrhagic teleangiectasia--argon laser

In 20 patients with hemorrhagic hereditary teleangiectasias (HHT) only 15 were treatable with argon laser. In the others septal perforation or continued bleeding made initial treatment inadequate. The laser treatment had to be repeated in all patients, due to multiplicity of lesions. Nine patients regarded the outcome very favourably with minimal bleeding episodes. In four of them the effect lasted more than one year.
