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

Patent ductus arteriosus

Current Treatment Options in Cardiovascular Medicine, 1999
In the absence of irreversible pulmonary hypertension, closure of clinically detectable patent ductus arteriosus (PDA) is usually recommended in adults. Device closure obviates the need for general anesthesia and a surgical incision and eliminates postoperative pain, long convalescence, and lifelong scarring.

The silent ductus arteriosus

The Journal of Pediatrics, 1978
Preterm infants at risk of developing a patent ductus arteriosus were followed sequentially by physical examination, echocardiographic determinations of the LA/AO ratio, and chest roentgenograms. The results show that a significant number of infants who have no clinical signs or symptoms of a PDA have large left-to-right shunts.

Aneurysm of the Ductus Arteriosus

Angiology, 1978
A 59-year-old man with an aneurysm of the ductus arteriosus is described. Macroscopically and histologically it was ascertained that the aneurysm had originated from the ductus arteriosus itself. We suggest the following pathogenesis: after obliteration of the pulmonary end, the aneurysm was formed, and as a result of a gradual increase in pressure in ...

The Patent Ductus Arteriosus

Clinics in Perinatology, 1978
This article focuses on the patent ductus arteriosus in the preterm infant. The results of recent laboratory investigations concerning the modulation of the caliber of the fetal ductus arteriosus by alterations in the prostaglandin milieu are discussed.

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 The ductus closes when this prostaglandin effect if withdrawn.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.
