Intrapulmonary shunts in cystic fibrosis.

Abstract

Eight children with cystic fibrosis were studied for intrapulmonary shunts. Evidence of right-to-left shunt was found in seven. Five of these also had left-to-right shunt at the precapillary level. The latter were demonstrated by cineangiography and by indicator dilution (indocyanine green dye) methods.
