Background Patent ductus arteriosus is a common congenital disorder (10% of congenital disorders). Ductus Botalli closure is the realm of invasive cardiology. Inability to perform ductus Botalli closure with percutaneous methods causes, that administration of indomethacin or surgery are nowadays treatment of choice. The aim is to present an alternative in treatment with minimally invasive surge...
Making a diagnosis of a patency of a ductus arteriosus is often difficult in the first few months or first year of life. When the diagnosis is in doubt, one may profitably turn to angiocardiography for help. In this paper a method of demonstrating the patent ductus by the injection of contrast medium is described. The practical importance of the correct diagnosis is presented with reference to ...
Patent ductus arteriosus (PDA) is a congenital heart disease defined as the arterial connection between the pulmonary artery and the aorta. The ductus arteriosus is an essential structure that shunts blood away from the lungs during fetal life, and only becomes abnormal if it remains patent more than three months after birth in term infants. Spontaneous delayed closure of the ductus arteriosus ...
While echocardiography has been used to noninvasively document indirect effects on the heart of left-to-right shunting through a patent ductus arteriosus, no noninvasive technique has been developed to image the duct itself. In this study, 35 sequential studies were performed on 28 patients with a mechanical sector scanner to image the distal pulmonary artery and its bifurcation by scanning alo...
BACKGROUND Transcatheter occlusion with Gianturco coils has been attempted in a small number of patients with tiny (< or = 1.5-mm diameter) patent ductus arteriosus, and preliminary results have been encouraging. The present study extends this method to larger ductus sizes and makes recommendations for proper coil size selection. METHODS AND RESULTS Coil occlusion was attempted in 24 consecut...
The cause of patent ductus arteriosus has not yet been established. Spitzer1 in his ontogenetic and phylogenetic explanation considers patent ductus arteriosus as a simple malformation due to an arrest of development. He was not aware that patency of the ductus can be accompanied by severe pulmonary hypertension (so-called reversed ductus) ‘ 5 7 even though in most cases the pressures of the le...
The effects on gut blood flow velocities of parenteral indomethacin (0.2 mg/kg) given either quickly as a bolus or slowly as an infusion were compared in consecutive studies of two groups of infants with symptomatic patent ductus arteriosus. In the presence of patent ductus arteriosus the range of velocities in the superior mesenteric artery before indomethacin was given was characterised by pr...
We report a case of left pulmonary artery sling associated with patent ductus arteriosus and atrial septal defect in a 21-month-old child. 256-slice MDCT provides valuable information, such as abnormal origin of the left pulmonary artery, the relationship between pulmonary artery and airway, the diameter of the patent ductus artery and atrial septal defect. The information is helpful in diagnos...
Patent ductus arteriosus is frequent in premature babies. With an incidence of 1:2500-5000, it accounts for 9% to 12% of congenital heart disease. Several different drugs have been tried for closure of hemodynamically significant patent ductus arteriosus. The first to be used was indomethacin, with a success rate of 70% and a reopening rate of 35%; however, the high cost of this drug has driven...
T he ductus arteriosus allows deoxygenated blood from the right ventricle through the descending aorta and to the placenta in the fetal period. Functional and anatomical closure is complete by several weeks after birth. Patients with ductus-dependent physiology generally have advanced congenital malformations and require surgical intervention early in life. However, some patients will present a...
