“…In 1981, Perlman et al 15 demonstrated reduced diastolic flow in the anterior cerebral arteries in premature babies with ductus arteriosus. Wilcox et al 16 reported their Doppler findings in the carotid arteries in 23 infants with PDA. They found that pandiastolic or late-diastolic reversal of flow in the carotid artery was associated with large or small ductus, respectively.…”

“…This is mainly due to the inability to maintain adequate diastolic perfusion through the capillary bed. A compensatory increase in systolic perfusion may take place, although this is probably not very effective as judged by the relatively normal systolic blood pressure and systolic blood flow velocity found in infants with PDA (7,22). Furthermore, the high pulsatility of the cerebral blood flow may be hazardous to the fragile periventricular capillaries, with risk for rupture and intraventricular hemorrhage (9).…”

“…Infants with large ductal shunts show flow patterns in the large systemic arteries suggesting low, absent or even reversed diastolic flow (6,7). Studies of intracranial arterial flow patterns indicate a poor antegrade flow in diastole, improving after ductus closure (8,9).…”

“…Doppler ultrasonography of cerebral arteries in preterm infants with a large patent ductus arteriosus (PDA) has been reported to show a decreased and sometimes retrograde diastolic blood flow [5,8,16]. These alterations might lead to cerebral ischaemia [10,11] and an increased probability of necrotizing enterocolitis (NEC) or renal failure [3,9].…”
