Use of tcPo2for Evaluation of Right to Left Shunts in Patent Ductus Arteriosus

Left-Sided Patent Ductus Arteriosus

W HEN there is a right-sided aortic arch, persistence of a left-sided ductus arteriosus can readily be demonstrated by angiocardiography. This is important because in some types of eyanotic congenital heart disease, such as in the tetralogy of Fallot, anl artificial aortico-pulmonary (Blalock-Taussig' or Pott S2 shunt) is often created in order to alleviate the distress produced by anoxia. Two ...

Intravenous Paracetamol and Patent Ductus Arteriosus Closure

Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...

Patent ductus arteriosus in a lamb: A case report

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...

Nonvisualization by aortography of patent ductus arteriosus associated with a large proximal left-to-right shunt.

Three cases are presented in which aortography failed to demonstrate the presence of a moderate-sized patent ductus arteriosus in association with a large proximal left to right shunt, but without other circumstances which would tend to diminish left to right shunt flow through the ductus. The ductus was not clinically apparent in any of these cases. Failure of expression of the distal lesion i...
