[Diagnosis and therapy of arteriovenous lung fistulas]

On the basis of 6 own cases, 5 of which were observed during one year, the clinical picture, the diagnostics and the therapy of the arteriovenous pulmonary fistula are described. Of decisive diagnostic importance is the angiography of the pulmonary artery which should always be used for the clarification of unclear pulmonary foci as well as clinically unclear cyanosis. For the removal of this shunt connection in the lesser circulatory system therapeutically only the operation comes into question. On account of the threatening complications and the inclination to the dilation of the fistula with growing age it is indicated also in cases with only slight haemodynamic effect. Dependent on the anatomical position of the fistula the ligature of the afferent artery is recommended.
