Abstract
-
BACKGROUND: Surgical closure of the PDA in premature infants with complications or
contraindications to indomethacin use, or recurrence of symptomatic PDA is a safe and
effective procedure with low operative risk and minimal complications.
MATERIAL AND METHOD: From April 1996 to August 1998, 11 premature infants with body weight
under 1.5 kg at operation underwent operation for a symptomatic PDA (male:5, female:
6). Associated dise ases were congenital heart disease(7), hyaline membrane disease(6),
intraventricular hemor rhage(4), pneumonia(4), pneumothorax(3), hyperbilirubinemia(2),
necrotizing enterocolitis(2), renal failure(1), epilepsy(1), and hydrocephalus(1).
Surgical techniques are hemoclipping(8) and ligation(3). The size of PDA was 3~6 mm (5.0+/-1.2).
RESULT: Systolic and diastolic blood pressure rised and heart rates decreased after PDA closure.
ABGA improved postoperatively. There were no surgical complications. Six infants with
improved ABGA data were weaned from mechanical ventilatory support. The follow-up durations
after discharge were 3 month to 12 month. Five deaths were not related to operation.
The causes of death were hyaline membrane disease(2), bronchopulmonary dysplasia with
pneumonia(1), sepsis(1), and con gestive heart failure with respiratory distress syndrome(1).
CONCLUSION
Early operative closure is the treatment of choice in most premature infants
with a hemodynamically significant shunt(PDA), recurrence of symptomatic PDA, complications
of Indomethacin, or contraindi cations to Indomethacin.
