Abstract

Background:

Transcatheter patent ductus arteriosus closure in premature infants is gaining attention with rapidly growing experience. The KA micro plug device poses many favourable features for ductus arteriosus closure in premature infants. The study aimed to describe the technique and outcomes of a KA micro plug in closing the ductus arteriosus in premature infants weighing less than 1500 g.

Methods:

This is a single-centre retrospective study in premature infants with patent ductus arteriosus weighing less than 1500 g who underwent off-label use of a KA micro plug at the Stead Family Children’s Hospital from February 2022 to December 2023.

Results:

Eighteen premature infants weighing less than 1500 g underwent attempted transcatheter ductus arteriosus closure using a KA micro plug device. Median weight, age, and corrected gestational age at the procedure were 943 g (682–1225), 26 days (9–79), and 28.5 weeks (25.6–32), respectively. The procedure was successful with complete closure achieved in all patients. No major haemodynamic instabilities were encountered. No catheterization-related complications were encountered. On a median follow-up of 10.9 months (0.1–19), all patients are alive with the device in a good position without residual shunt or abnormal findings.

Conclusion:

KA micro plug device for patent ductus arteriosus in infants weighing less than 1500 g is feasible, safe, and effective. We recommend that manufacturers of devices used to close the ductus arteriosus in small infants enhance both the devices and their delivery systems to simplify the procedure and mitigate the risk of haemodynamic instability.
