Brain, Gut and Kidney Blood Flow During Medical Closure of PDA
The purpose of this study is to determine how the medications which are used to close the patent ductus arteriosus (PDA) in preterm infants affect brain, kidney and gut blood flow when compared to infants that are not treated with these medications. The medications being used for PDA closure are indomethacin and neoprofen.
All babies requiring medical treatment of their PDA will receive up to 3 doses of medication. For babies enrolled in the control group of this study, she/he will not be treated with either of these medicines.

Medical and Biotech [MESH] Definitions
Ductus Arteriosus, Patent
A congenital heart defect characterized by the persistent opening of fetal DUCTUS ARTERIOSUS that connects the PULMONARY ARTERY to the descending aorta (AORTA, DESCENDING) allowing unoxygenated blood to bypass the lung and flow to the PLACENTA. Normally, the ductus is closed shortly after birth.
Persistent Fetal Circulation Syndrome
A syndrome of persistent PULMONARY HYPERTENSION in the newborn infant (INFANT, NEWBORN) without demonstrable HEART DISEASES. This neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). The newborn patient exhibits CYANOSIS and ACIDOSIS due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (DUCTUS ARTERIOSUS, PATENT) and at times a patent foramen ovale (FORAMEN OVALE, PATENT).
A fetal blood vessel connecting the pulmonary artery with the descending aorta.
Hypoplastic Left Heart Syndrome
A condition caused by underdevelopment of the whole left half of the heart. It is characterized by hypoplasia of the left cardiac chambers (HEART ATRIUM; HEART VENTRICLE), the AORTA, the AORTIC VALVE, and the MITRAL VALVE. Severe symptoms appear in early infancy when DUCTUS ARTERIOSUS closes.
Truncus Arteriosus, Persistent
A congenital anomaly caused by the failed development of TRUNCUS ARTERIOSUS into separate AORTA and PULMONARY ARTERY. It is characterized by a single arterial trunk that forms the outlet for both HEART VENTRICLES and gives rise to the systemic, pulmonary, and coronary arteries. It is always accompanied by a ventricular septal defect.
The purpose of the study is to determine the safety and efficacy of ibuprofen, compared with indomethacin, in the treatment for the closure of the patent ductus arteriosus in premature bab...
The purpose of this study is to determine if increasing the ibuprofen dose will increase the likelihood of closing the patent ductus arteriosus in premature babies.
The ductus arteriosus directs blood away from the pulmonary circulation and toward the systemic circulation during fetal life, then closes after birth. In preterm infants the incidence of...
Patency of the ductus arteriosus (PDA) is functionally essential for fetal circulation, however persistence of ductal patency postnatally may have significant adverse hemodynamic effects i...
The investigators hypothesize that early intervention to optimize regional cerebral oxygenation detected by cerebral oximetry monitoring during deep hypothermic circulatory arrest (DHCA) f...
OBJECTIVE: To investigate whether accurate estimation of the diameter of the patent ductus arteriosus can be obtained by colour Doppler echocardiography. METHODS: The minimum and maximum diameters of...
Constriction of the fetal ductus arteriosus in utero can be caused by pharmacological agents or can occur spontaneously. The spontaneous constriction and closure of the ductus arteriosus have been rep...
Postnatal closure of the ductus arteriosus is crucial in the circulatory adaptation of the newborn to extrauterine life. In recent years, many studies have been performed to improve our understanding...
Abstract A 73-year-old woman who had undergone ligation of patent ductus arteriosus (PDA) via a left thoracotomy 19 years earlier was admitted to our hospital under the diagnosis of thoracic aortic an...
A 35-year-old man was admitted to the hospital with prolonged high-grade fever. Chest computed tomography revealed multiple pulmonary infiltrations in both lungs, suggesting septic emboli. Echocardiog...
