[Endovascular embolization of arteriovenous lung fistulas (review of literature and own results)].

The authors analyze the literature data on and their own experience in endovascular closure of arteriovenous lung fistulas: 20 fistulas were closed in 12 patients, in whom transcutaneous catheterization of the pulmonary artery was performed. Large-frame angiopulmonography made it possible to reveal 10 common arteriovenous lung fistulas (7 single and 3 multiple ones). Afterwards the diagnostic procedure was turned into a therapeutic one. Several types of spirals, spongogel fragments, pieces of felt and pools with wool were used as embolizing materials. All these measures resulted in hermetic closure of the arteries and a complete stop of pathological right-left shunting of the blood at the lung level and positive dynamics of blood gaseous indices.
