title: Pulmonary arteriovenous fistulas.
abstract: During the 20-year-period 1959-78, 7 patients with pulmonary arteriovenous fistula were treated at the Department of Thoracic and Cardiovascular Surgery. There were 5 men and 2 women, with a mean age of 26 (14-47) years. Cyanosis with elevated haematocrit was present in 4, dyspnoea in 4, neurological signs in 3 (including one brain abscess and one hemiplegia). Systolic hum was audible in 3 cases. Three patients had the hereditary type of the disease (Rendu-Osler-Weber) with telangiectasiae also elsewhere in the body. The calculated right-to-left shunt varied from 14 to 56 per cent of the cardiac output. The treatment was lobectomy in all cases (4 upper lobe, one middle lobe and 2 lower lobe resections). The patient with a brain abscess underwent craniotomy prior to lobectomy and developed epilepsy necessitating anticonvulsive treatment. The other patients had an uneventful recovery with relief of the symptoms. During the follow-up time (2-20 years), one patient (with hemiplegia) died of myocardial infarction 10 years after the operation. The others were doing well. It is concluded that the safest way to treat a pulmonary arteriovenous fistula is to operate as soon as it has been detected in order to prevent the complications so often associated with the disease.
