چکیده

The adrenergic innervation of the patent human ductus arteriosus was studied using the Falck-Hillarp fluorescent histochemical method for the localization of monoamines. Few adrenergic terminals were demonstrated in the muscular layers of the patent ductus arteriorms in 14 specimens examined. The innervation to the adventitia was sparse to moderate. The possibility that a developmental abnormality in the sympathetic innervation may contribute to patency of the ductus arteriosus is discussed.

Patent ductus arteriosus in a lamb: A case report

Patent ductus arteriosus (PDA) is a persistent patency of a vessel normally present in the fetus that connects the pulmonary arterial system to the aorta. The ductus arteriosus fails to close at birth when breathing commences and placental blood circulation is removed. Closure of the ductus arteriosus arises in response to decline pulmonary vascular resistance and increased systemic vascular re...

Early Ductus Arteriosus Constriction: A Rare Case Presentation at 18 Weeks of Gestation

The ductus arteriosus (DA) is a vital structure in fetal circulation, carrying about two thirds of the right ventricular (RV) output to the aorta. During fetal life, ductal patency is actively preserved by several different factors, and pathologic ductal constriction causes right-sided pressure overload of the heart, leading to RV failure. There have been many reports of ductal constricti...

Coarctation of the Aorta Complicated by Patency of the Ductus Arteriosus

The study of the anatomic and hemodynamic relationships in a case of coaretation of the aorta complicated by patency of the ductus arteriosus and pulmonary hypertension indicated the necessity for a physiologic approach to the classification of coarctation of the aorta. The origin of existing classifications has been briefly traced and basic anatomic and physiologic considerations in this malfo...

Patent ductus arteriosus: lack of evidence for common treatments.

Patent ductus arteriosus (PDA) is a common diagnosis among extremely premature infants, especially in those with lung disease. Treatments are often used to close the PDA. Despite nearly three decades of research, the question of whether the benefits of treatments to prevent ductal patency or promote closure outweigh the risks of these treatments remains unanswered. The authors rarely use treatm...
