Coarctation of the aorta with patent ductus arteriosus

Persistence of Fetal Ductus Function after Birth

Within recent years there has been increasing interest in the presence of reversed flow through the ductus arteriosus. Most reported cases have been in older children and young adults. There is a group of cases in which the ductus serves as a site of a veno-arterial shunt in infancy, and thus continues to perform its fetal function. The conditions under which veno-arterial shunting persists after birth are illustrated and analyzed, and an effort is made to clarify the common features of these lesions.

Radiologic aspects of operable heart disease. II. Retrograde brachial aortography

Patent ductus arteriosus and coarctation of the aorta are common causes of congestive heart failure in infancy, yet are more difficult to diagnose than in later life. Retrograde brachial aortography is a relatively simple method of establishing the diagnosis with assurance. A description ofthe technic is followed by a discussion of the normal aortogram in infancy. A relatively large series of cases, in which a high diagnostic yield was obtained, is analyzed. The hazards of the procedure are few if highly concentrated media are avoided and careful attention is paid to details of technic.
