Question
My daughter was born 10 days ago and was found to have an unclosed arterial duct (0.9mm). The child is now 110 days old and weighs 6.4 kilograms. Can an unclosed arterial duct heal on its own?
Answer
Generally speaking, arterial ducts that are five millimeters or less can heal on their own. Based on your description, there is only one millimeter, which is not a concern. If there are no complications, it should heal on its own without any worries. An unclosed arterial duct of one millimeter does not require surgery and most cases can heal spontaneously. It is recommended to have regular follow-up checks and there is no need to rush into surgery.
