Background: The persistence of ductus arteriosus, the aim of this study is to evaluate the possible benefit in the treatment for ductus closure when an early less than 72 hours of life echocardiographic screening is done versus when the echocardiographic diagnosis is realized only in present of associated symptoms. Methods: Preterm without malformation followed by two strategies: patent ductus arteriosus PDA screening or echocardiographic study on suspected PDA for symptoms control group. We analyzed the ductus characteristics, the presence of pulmonary hypertension and the treatments for their closure. Results: There was no difference in the proportion of newborns diagnosed with PDA among the strategies screening There were no differences in relation of the ductus characteristic among the groups. The closure treatment were similar in the two strategies among the moderate and late preterm, but was more aggressive in the control group in the extreme preterms.

Patent ductus arteriosus or arteriosum PDA is a congenital cardiac anomaly where there is persistent patency of the ductus arteriosus , a normal connection of the fetal circulation between the aorta and the pulmonary arterial system that develops from the 6 th aortic arch.
The ductus is a necessity in utero but usually undergoes functional closure 48 hours after birth. Patency of the ductus may be isolated or associated with other cardiac anomalies. In some circumstances, it is necessary to prolong life in patients with severe structural heart disease in whom a normal systemic circulation would be incompatible with life:. Chest radiographic features may vary depending on whether it is isolated or associated with other cardiac anomalies and with the direction of shunt flow right to left or left to right.
Can have cardiomegaly predominantly left atrial and left ventricular enlargement if not complicated. Obscuration of the aortopulmonary window and features of pulmonary edema may be evident. Transesophageal and transthoracic echocardiography have been used to identify these lesions, assess for the presence of complications, and plan surgical intervention.
With transthoracic echocardiography , the parasternal short axis view at the level of the aortic valve with color flow Doppler allows visualization of the flow through a patent ductus arteriosus. It classically appears as a high-velocity jet directed from the far-field toward the main pulmonary artery. Continuous wave Doppler interrogation reveals continuous flow throughout systole and diastole.
The suprasternal notch view may also depict aliased, continuous flow from the proximal descending aorta toward the right pulmonary artery, visible under the aortic arch in short-axis.
A ductus may have a tortuous morphology that does not fit in the Krichenko classification. This ductus type is usually observed in premature children and some authors proposed to classify it as type F or fetal type. Compared to types A to E, a type F ductus is larger, longer, tapers minimally from the aortic to pulmonary end, with a tortuous connection to the pulmonary artery giving a hockey-stick appearance 9.

[Echocardiographic Screening vs. Symptomatic Diagnosis for Patent Ductus Arteriosus in Preterms]
Galen's vein aneurysm as cause of heart failure. Correspondencia: Gabriel Cassalett, MD. We present the case of a newborn admitted to the intensive care unit with a heart failure of difficult medical management. A large ductus arteriosus was found. It was surgically corrected, but the heart failure persisted and did not improve with medical treatment. Incidentally, a big Galen's vein aneurysm was found.
Abstract Patent ductus arteriosus is treated according to its indications conservatively with medications or by surgical closure; the latter was traditionally performed by an open technique, then later, the percutaneous approach was developed for selected cases and finally, in recent years, it has been done by thoracoscopic surgery with success challenging percutaneous results. However, at our hospital, this had not been tried before. We present the case of a female patient who met the ideal criteria for this procedure to be performed and in whom it was successfully accomplished without complications; hence our report, motivated by the historical importance and as a baseline for future cases. First published case of thoracoscopic patent ductus arteriosus closure in the general hospital of Mexico Dr. Eduardo Liceaga. Latorre-Davilac, C.
Objetivo: Comparar respuesta al tratamiento con diclofenaco vs ibuprofeno en cierre de DAP. Directory of Open Access Journals Sweden. Full Text Available We report a case of an acute mechanical haemolisis in a woman of 50 years old that ocurred after a percutaneous closure of a patent ductus arteriosus by a Rashkind double umbrella prosthesis. Surgical removal of the device using Cardiopulmonary bypass and ligation of the duct were required before haemolisis was abolished. Rev Med Hered ;
