Ductus arteriosus: more than just the patent ductus arteriosus

Pediatric Radiology, 2022
The ductus arteriosus is important to fetal circulation. Failure to close at birth is a common event. In this educational pictorial essay, we illustrate the association of the ductus arteriosus with a variety of congenital cardiac, vascular and pulmonary lesions. These lesions can impact the systemic circulation, the pulmonary circulation or the airway

Control of the ductus arteriosus

Physiological Reviews, 1975
In the fetus the major function of the ductus arteriosus is to divert flow away from the lungs toward the placenta, therby avoiding unnecessary circulation through the lungs and reducing the work load of the heart. Constriction of the ductus arteriosus is produced by several mechanisms that may interact with one another in producing normal postnatal ...

Role of Transcatheter patent ductus arteriosus closure in extremely low birth weight infants

Catheterization and cardiovascular interventions, 2018
Patent ductus arteriosus (PDA) is common in extremely low birth weight (ELBW) infants. The objectives of this study were to describe our early clinical experience of transcatheter PDA closure (TCPC) in ELBW infants, compare outcomes with surgical ...

Percutaneous closure of patent ductus arteriosus in premature infants: A French national survey

Catheterization and cardiovascular interventions, 2019
Transcatheter closure of patent ductus arteriosus (PDA) in premature infants has been shown to be feasible in small series. Outcomes in larger series are currently lacking.

Use of carotid and axillary artery approach for stenting the patent ductus arteriosus in infants with ductal‐dependent pulmonary blood flow: A multicenter study from the congenital catheterization research collaborative

Catheterization and cardiovascular interventions, 2019
Carotid artery (CA) and axillary artery (AA) access are increasingly used for transcatheter stenting of the patent ductus arteriosus (PDA), although reports are limited.

Patent ductus arteriosus, its treatments, and the risks of pulmonary morbidity.

Seminars in Perinatology, 2018
A persistent left-to-right shunt through a patent ductus arteriosus (PDA) increases the rate of hydrostatic fluid filtration into the lung's interstitium, impairs pulmonary mechanics, and prolongs the need for mechanical ventilation.

Prostaglandins and the Ductus Arteriosus

Annual Review of Medicine, 1981
Fetal patency of the ductus arteriosus is an active state maintained by the relaxant action of a prostaglandin, most probably prostaglandin E2. This PG mechanism is most active in the immature ductus and decreases toward term. The ductus closes when this prostaglandin effect if withdrawn.

The Rabbit Ductus Arteriosus

Nature, 1957
THE ductus arteriosus differs structurally and functionally from other large arteries. It is almost devoid of elastic tissue, and its smooth muscle fibres have a specific disposition1,2. In the rabbit, fine nerve fibres ending in relation to the muscle, as well as sensory type endings, have been described3.

Pharmacology of the Ductus Arteriosus

Pediatric Clinics of North America, 1981
Dramatic advances in the understanding of the factors that control normal patency of the ductus arteriosus during fetal life and that allow its closure after birth have resulted in major new therapeutic approaches to the management of infants with congenital heart disease. Infusion of PGE 1 and PGE 2 have been used in several congenital malformations
