The flow velocity pattern in the descending aorta, renal arteries, and
celiac and superior mesenteric arteries was studied with pulsed Doppler in
eight premature babies with symptomatic ductus arteriosus before and after
ductal closure, as compared to nine premature babies without ductus
arteriosus. There was a decrease or reversal of flow in diastole in the
above arteries in babies with ductus and diastolic flow reappeared after
ductal closure. This diastolic steal phenomenon has not been previously
demonstrated in the abdominal arteries. It may contribute to proneness to
ischemic damage of abdominal organs in premature babies.
