Management of bilateral ductus arteriosus in complex cyanotic heart disease

Bilateral ductus arteriosus (BDA) usually is associated with complex
cyanotic heart disease. Since pulmonary valve atresia often is part of the
complex, hypoxia may necessitate emergency cardiac catheterization and
surgery for these critically ill newborn infants. Optimum management
depends on accurate delineation of the intracardiac and great vessel
anatomy. Since the ductus arteriosus has a tendency to close spontaneously,
the true anatomy of the fourth to sixth aortic arch connections should be
determined on the first catheterization. An over-all plan for future care
by the medical-surgical team should have been made at the time of the
initial surgical procedure. The case histories of four newborn infants with
BDA associated with cyanotic heart diseases are reported. The anatomy and
basic embryology of the fourth to sixth arch system is reviewed and
recommendations for long- term management are given.
