[Digital subtraction angiography (DSA) of arteriovenous pulmonary fistulae].
A-V fistulae of the lungs are almost invariably congenital malformations; depending on their size, they may lead to the picture of a right-to-left shunt with hypoxia, cyanosis and polycythaemia. Chest x-rays, tomograms and CT demonstrate larger fistulae. In order to demonstrate small fistulae, and for pre-operative investigation, angiography is required. DSA is able to replace conventional pulmonary angiography. A patient with five A-V fistulae is described, in whom three could only be seen with the help of DSA.
