Transvenous double-balloon occlusion of the persistent ductus arteriosus: an experimental study
Pediatric Cardiology
|April 1, 1984
Summary
A novel transvenous catheter device effectively closes persistent ductus arteriosus (PDA) in pediatric models. This innovative silicone plug offers a safe and biocompatible solution for PDA closure.
Area of Science:
- Cardiovascular Medicine
- Pediatric Cardiology
- Medical Devices
Background:
- Persistent ductus arteriosus (PDA) is a common congenital heart defect in infants and children.
- Existing closure methods may have limitations, necessitating novel approaches.
Purpose of the Study:
- To introduce and evaluate a new transvenous catheter-based device for PDA closure.
- To assess the efficacy and biocompatibility of a detachable silicone plug for PDA occlusion.
Main Methods:
- Development of a 5F/6F triple-lumen catheter with a detachable silicone double-balloon.
- Testing the device in 21 beagles with surgically created PDA models.
- Evaluation of occlusion, tissue integration, and biocompatibility over up to two years.
Main Results:
- The device successfully occluded the simulated PDA in all beagle models.
- Fibrous tissue ingrowth at the plug ends ensured permanent occlusion within one month.
- Long-term follow-up confirmed the silicone plug's biocompatibility.
Conclusions:
- The novel transvenous catheter closure method is a suitable and effective treatment for PDA.
- The silicone plug demonstrates excellent biocompatibility and potential for permanent PDA occlusion.
- This device offers a promising new option for pediatric PDA management.
