Abstract:
Hereditary hemorrhagic telangiectasia(Osler-Rendu-Weber Syndrome) is characterized by telangiectasia of the skin and mucous membranes and intermittent bleeding from vascular abnormalities. About 20% of patients with this is syndrome have pulmonary arteriovenous fistulas. Pulmonary arteriovenous fistula is uncommon malformation which has an abnormal connection between the pulmonary capillary bed, in which venous blind in the pulmonary artery is shunted through the fistula into the pulmonary vein without exposure to alveolar oxygen and result in unoxygenated, desaturated systemic arterial blood, polycythemia, cyanosis and clubbing. Death often results from cerebral abscess and rupture of the malformation with massive hemorrhage. Therapeutic intervention is recommended for all symptomatic patients because of the risk of those serious complications. Treatment options include surgery and transcatheter obliteration with steel coils or detachable balloons. Therapeutic embolization has the advantages that multiple bilateral pulmonary arteriovenous fistulas can be occluded and also that the procedure can be repeated if necessary. Recently we experienced a case of the multiple bilateral pulmonary arteriovenous fistulas associated with telangiectatic change of hepatic artery and multiple angiodysplasia on the gastric mucosa in 41 years old female patient who had mild dyspnea of exertion(NYHA class II), clubbing finger, severe iron deficiency anemia. She was treated with embolization technique using steel coils and iron replacement. After the therapeutic embolization, significant improvement of dyspnea of exertion with disappearance of multiple pulmonary nodule on follow-up simple chest x-ray was noted. During the subsequent six months follow-up period, she bad the improvement of symptoms arid iron deficiency anemia.
