Patent Ductus Arteriosus

چکیده
The impression that has been gathered from a perusal of the available literature is that a patent ductus arteriosus as a sole abnormality is comparatively rare. In Abbott's' coliected series of 850 cases there were but 73, and in Laubry and Pezzi's2 well-known work the lesion is said to be rare. Recently Perry3 in a review of congenital heart lesions in Bristol school children found, amongst 121 cases, 8 instances (6 per cent.) of patent ductus arteriosus. In our own series of 88 cases of congenital heart disease occurring for the most part in school children, we find no less than 20 cases or 23 per cent. of the total to have signs which suggest a patent ductus arteriosus as the sole abnormality. Much has been written with regard to this abnormality, for where it has been discovered it has usually been well studied. Perhaps it is the most completely investigated lesion in congenital cardiac pathology.

متن کاملEvaluation of Cortisol Level in Premature Neonates: Are There any Correlations between Prevalence of Patent Ductus Arteriosus and Prenatal Administration of Betamethasone?
Background: The results of previous studies suggested that there is an increased risk of patent ductus arteriosus (PDA) in the neonates with lower serum cortisol levels. This study aimed to assess the association between serum cortisol values and PDA and investigate if there is an association between PDA and the antenatal administration of betamethasone.
