The symptoms of patent ductus arteriosus are usually so slight that they are not noticed until the child is older and more active. He then begins to experience dyspnea on exertion. If the ductus is large there may be retardation of growth. Pulmonary congestion may result from poor left ventricular function. The heart compensates through hypertrophy and dilation.
Treatment is surgical ligation of the open ductus, preferably when the child is from 4 to 10 years of age. Prognosis, when the condition is not accompanied by other congenital heart defects, is excellent.
The ductus may remain open in as many as 10 per cent of preterm infants, especially those under 1500 grams. If the shunt across the ductus is large, heart failure can occur and surgical repair may be necessary. Investigators into the effects of the prostaglandins have reported that closure of a patent ductus arteriosus can be produced in preterm infants by administration of an inhibitor of prostaglandin formation. Conversely, in neonates suffering from severe complex congenital heart defects in which an open ductus arteriosus could be beneficial, injections of prostaglandins have been used to keep the channel open.

Patient discussion about patent
Q. How open are you about telling people that you are bipolar? I am studying in a coed college and am high scoring and talented. Actually I am a guitarist who entertains most of my peers. So I have lots of friends. For the past 8 months I could not use my guitar because of my busy study schedule. Without music I feel very depressed. My attitude has changed. My friends started deserting me because of my depression. So I started hating life and checked with a psychiatrist who diagnosed as bipolar. I fear whether I will lose my friends. So this question is to bipolar people: How open are you about telling people that you are bipolar?
