Closure of the ductus arteriosus

Authoring team

There are a number of approaches:

  • in a neonate in intensive care fluid restriction may be a first line of management
  • indomethacin inhibits prostaglandin synthesis and may cause closure of the ductus
  • Some evidence suggests that ibuprofen may be just as effective as indomethacin and less toxic particularly to the kidneys.
  • surgical ligation may be undertaken following medical correction of any signs of heart failure

A systematic review concluded (1):

  • High-certainty evidence shows that indomethacin is effective in closing a symptomatic PDA compared to placebo or no treatment in preterm infants. Evidence is insufficient regarding effects of indomethacin on other clinically relevant outcomes and medication-related adverse effects
