[Surgical correction of congenital arteriovenous aneurysms of the lungs].

The authors have analyzed results of the surgical treatment of 24 out of 26 patients observed at the clinic for arterio-venous aneurysms of the lungs. It was found that the reduction of efficiency of the gas exchange function of the lungs before operation manifested itself by arterial and venous hypoxemia with an increased arterio-venous oxygen difference and pronounced decrease of blood oxygen strain. Good results of the operative treatment, rapid recovery of blood oxygenation, disappearance of hypoxemia symptoms make the surgical method the only radical one in treatment of such patients. The operation of choice was lobectomy. No lethal outcomes followed.
