[Nonsurgical treatment of pulmonary arteriovenous aneurysms].

Four patients with single or multiple pulmonary arteriovenous aneurysms, including three with Rendu-Osler's disease, were treated by occlusion with metallic spirals of the supplying pedicles during angiography. Results are compared with those of 16 cases treated by the same method and reported in the literature. The technique and its therapeutic indications are discussed based on these 20 cases and a review of documented data concerning 502 other cases with these aneurysms.
