title: Asymptomatic reopening of ductus arteriosus after successful closure by indomethacin in premature infants.
abstract: Indomethacin has been demonstrated to be effective for closure of hemodynamically symptomatic patent ductus arteriosus (PDA) in premature infants. The five cases in this study had acquired asymptomatic reopening of PDA a long time after successful closure by oral indomethacin. Providing adequate oxygen, giving another course of indomethacin, preventing excessive fluid intake and keeping hematocrit level greater than 40% had been tried to close the ducti but all in vain. However, most could be expected to close spontaneously later. Herein, the possible contributing factors and the treatment rationale are discussed.
