To research the clinical, paraclinical characteristic of ductus arteriosus in newborns at National Institute of Pediatrics from 2000 – 2003

ABSTRACT

A retrospective survey on 31 cases of patent ductus arterious diagnosed echocardiographically at the National Institute of Pediatrics in 2000-2003 year period. The disease occurred mainly in prematurily newlyborn infants (74.2%) continuous murmur was found in 10%, systolic murmur in 90% of case in the average age of infant of 5.1  2 days. In premature newborn, their condition was usually combined with the post natal respiratory distress, while in immature newborn infants, it was congenital abnormality and fetal malnutrition. The most common sign was respiratory distress in combining with other respiratory pathologies (58.1%). On X-ray image, 73.1% had had large left heart, proportionally with the sign of urterial duct. The increase of pulmonary arterial pressure in medium levels was common. The > 3mm diameter of arterial duct had impacted to clinical features and hemohynamics of the patients.
