The ductus arteriosus has a significant role in the fetal circulation connecting the main pulmonary artery to the aorta. Normally, after birth, it functionally closes within few hours but complete obliteration occurs at 2 to 3 weeks of age. Failure of the ductus arteriosus to close leads to the condition patent ductus arteriosus.

The physiopathology of the patent ductus arteriosus
The Journal of Maternal-Fetal & Neonatal Medicine, 2009Patent ductus arteriosus (PDA) remains a frequent problem for the very low birth weight infants. Many questions about the role of PDA, the best method of diagnosing it and the appropriate timing of treatment have been, at time, not completely answered.

Robert Gross stated that his first ligation of a patent ductus arteriosus in 1938 “formed the opening wedge in the surgical attack on congenital cardiovascular anomalies.”9 Ligation or division of the ductus has become a simple procedure associated with almost no morbidity or mortality.

THE PROFESSIONAL SETTING August 1938! Few physicians of today can be fully aware of the forces at play on a surgeon contemplating a new procedure in that year. Even those of us still alive who were active then find it difficult to recreate the setting. I will try to recall some conditions and events.

Patent ductus arteriosus (PDA) is the most common cardiac abnormality of the preterm infant. Its incidence is inversely related to gestational age, such that it affects almost 60% of infants less than 28 weeks’ gestation. Data published in 2007 demonstrated that spontaneous closure of the ductus occurs in 30% of infants with birthweights below 1500 g ...

The incidence of PDA is inversely related to gestational age in premature infants. Clinical presentation of PDA in premature infants is different than in older children. They present with increased work of breathing or an increasing need for mechanical ventilatory support.

Persistent Patent Ductus Arteriosus
International Journal of Technology Assessment in Health Care, 1991Two observations about the ductus arteriosus are established: most normally developed infants will have a patent ductus arteriosus (PDA) at the time of delivery, and most fullterm infants will have anatomic obliteration of the ductus lumen by 3–6 months of age.

Ductus Arteriosus and the Mechanism of Closure
New England Journal of Medicine, 1970IN the recent studies on closure of the ductus arteriosus, whole-body freezing and sectioning have made the ductus available for morphologic studies in a state that can be considered to reflect its state in vivo1 , 2 rather than distorted by artifacts. In newborn infants the ductus arteriosus has a circular lumen with a smooth inner surface, and a thin

Medical Journal of Australia, 1960 Ductus arteriosus (Ductus Botalli)
2004Ein offener Ductus arteriosus ist nicht selten, sondern findet sich bei 5–10% aller angeborenen Herzfehler. Er wurde erstmals 1938 durch Gross u. Hubbard ligiert [59]. Die gegenwartig am meisten verwendete Technik der 3fachen Ligatur wurde 1946 von Blalock [13] eingefuhrt. Die Moglichkeit der Indomethacintherapie wurde erst 1976 von Heymann et al. [63]
