[Surgical treatment of pulmonary arteriovenous fistula: report of two cases].

Two patients with surgical intervention for pulmonary arteriovenous fistula were presented. Lobectomy was performed in a cyanotic patient and fistula excision in another. To prevent the unsatisfactory prognosis of pulmonary arteriovenous fistula, surgical treatment is preferable to drug therapy when the diagnosis of this disease is established. The operative method should be selected according to the size, shape and localization of pulmonary arteriovenous fistula.
