in this retrospective study, 510 infants and children with patent ductus arteriosus (pda) who underwent surgery at the shahid rajai heart hospital in tehran were evaluated to determine the rate of surgical complications, morbidity and mortality. 30 patients (6%) developed minor to major complications postoperatively. four patients who had undergone pda ligation without division required reopera...

background and objective: nonsteroidal anti-inflammatory agents are the treatment of choice for ductal closure in premature newborn. this study evaluates early and late outcome, as well as the effectiveness of oral ibuprofen in the treatment of patent ductus arteriosus (pda) in premature infants. methods: in this clinical trial, all preterm infants below 37 weeks, with documentation of pda were...

BACKGROUND Patent ductus arteriosus is a risk factor for the development of necrotizing enterocolitis. The use of indomethacin to treat patent ductus arteriosus in preterm infants may either decrease the incidence of necrotizing enterocolitis by stabilizing or closing the ductus arteriosus or increase its incidence by a direct constricting effect on mesenteric blood vessels. The authors sought ...

The ductus arteriosus connects the pulmonary artery with the aorta and allows right ventricular blood to bypass the unexpanded lungs. In mature infants, the ductus arteriosus closes after birth. Patent ductus arteriosus occurs in 70% of preterm infants with a birth weight < 1,000 grams. Failure of the ductus arteriosus to close has been associated with intraventricular hemorrhage, necrotizing e...

OBJECTIVE: Early diagnosis of significant patent ductus arteriosus reduces the risk of clinical worsening in very low birth weight infants. Echocardiographic patent ductus arteriosus shunt flow pattern can be used to predict significant patent ductus arteriosus. Pulmonary venous flow, expressed as vein velocity time integral, is correlated to ductus arteriosus closure. The aim of this study is ...

proximity of the vagus nerve to a patent ductus arteriosus (pda) can cause traction or entrapment of vagus nerve during surgical closure of the in rare occasions. this can lead to a life threatening postoperative bradycardia. herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. the patient was managed by re-opening the chest, lung r...

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...

patent ductus arteriosus (pda) is an open communication between the upper descending thoracic aorta and the proximal left pulmonary artery, which results from persistence of the fetal ductus arteriosus. it may be isolated or occur with other congenital cardiac anomalies. aneurysms of the ductus arteriosus are rare lesions which may occur as a spontaneous. infantile fonn or occur in later childh...

OBJECTIVES The risk of infective endarteritis in patients with patent ductus arteriosus seems to have declined during the last 30-40 years, and cases of patent ductus arteriosus complicated by infective endarteritis are now very rare. Moreover, with the introduction of antibiotics, there has been a dramatic reduction in mortality from infective endocarditis. Despite these changes, however, the ...

Preterm infants with symptomatic patent ductus arteriosus had considerably raised plasma concentrations of atrial natriuretic peptide. Surgical ligation of the patent ductus arteriosus was associated with an immediate fall in plasma atrial natriuretic peptide concentration. Thus left to right shunting and left atrial distension may cause atrial natriuretic peptide release in preterm infants wit...
