[A case of pulmonary arteriovenous malformation treated surgically]

Pulmonary arteriovenous malformation is a rare abnormality consisting of a direct connection between the arteries and the pulmonary veins. Most of the malformations are related to hereditary hemorrhagic telangiectasia, although 10 to 20% cases are idiopathic. Clinical manifestations are due to right-to-left shunting. Embolization is the treatment of choice, when it is possible and accessible. Surgery continues to be appropriate in certain cases. We report the case of a woman who presented with an isolated complex arteriovenous malformation fed by two afferent arteries, a lingular one and an antero-basal one. Surgical treatment by lingual and antero-basal bisegmentectomy was undertaken with a good outcome.
