No results posted yet for this study

Summary

The ductus arteriosus quickly closes itself. is an important channel connecting the maternal fetal circulation before birth. After birth, this ductus arteriosus generally no longer has a physical function, so ductus arteriosus quickly closes itself. The persistent presence of ductus arteriosus leads to significant pressure changes in the systemic and pulmonary circulation, which have adverse effects on extremely/very premature infants. Therefore, persistent patent ductus arteriosus (PDA) is a systemic disease.
