AbstractThe ductus arteriosus derived from the sixth aortic arch, connecting the main or proximal left pulmonary artery to the descending aorta.ductal shape, length, and diameter are variable which may influence efficacy of various therapeutic approaches (1, 2). PDA (patent ductus arteriosus) increases in infants with low birth weight. In full-term newborns the ductus usually closed within the first ten hours of life by physical examination and within two days by echocardiography (3).
Complex maternal and fetal prostaglandins' interactions regulate the ductal closure (4). PDA flow turbulence is significant to produce a murmur is commonly thought to be capable of producing a jet lesion and increase the risk of endocarditis justifying closure (5).
