title: Ligation of the patent ductus. Technical considerations at different ages.
abstract: Over a 10 year period, 185 patients have been treated for patent ductus, including nine premature infants with a respiratory distress syndrome. Thirty-five other infants have had duct obliteration during the neonatal period, the incidation for surgery being intractable heart failure. Six of 18 adults had calcification or aneurysm in the duct region. three of these required extracorporeal circulation for duct control and closure. The remaining patients were from 1 to 18 years of age and underwent elective duct obliteration. Double ligation of the duct is regarded as the simplest, safest, and quickest technique generally applicable. Special techniques are required for fragile, broad, calcified, hypertensive, and conical ducts.
