Insights
Transcutaneous closure of patent ductus arteriosus (PDA) in children has a 5.1% major complication rate, often appearing within 24 hours. Longer-term surveillance is advised for patients receiving ADO1 devices due to potential late obstruction.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcutaneous closure of patent ductus arteriosus (PDA) is a common pediatric procedure.
- Variability exists in long-term follow-up by pediatric cardiologists.
- Characterizing complications and discharge timing can optimize patient care.
Purpose of the Study:
- To determine complication rates following transcutaneous PDA closure in children.
- To assess the timing of discharge after PDA closure procedures.
- To identify factors associated with postoperative complications.
Main Methods:
- Retrospective study of pediatric patients (0-15 years) undergoing transcutaneous PDA closure.
- Data collected from January 2006 to December 2015 at a single center.
- Analysis of complication types, severity, and timing relative to the procedure.
Main Results:
- 12% of 156 patients experienced complications; 5.1% had high-grade issues (e.g., device embolization, need for surgery).
- Moderate to low-grade complications (e.g., flow acceleration) occurred in 6.4%; 77% were immediately apparent.
- 2% developed late mild-to-moderate aortic or LPA obstruction, particularly with larger ADO1 devices; younger age and larger device size were risk factors.
Conclusions:
- PDA occlusion has a 5.1% major complication rate, typically seen within 24 hours.
- A small percentage (2%) treated with ADO1 devices developed late obstruction, warranting continued surveillance.
- Longer-term follow-up may be prudent for patients receiving ADO1 devices, especially those with larger ducts.
Background:
Transcutaneous closure of patent ductus arteriosus (PDA) in childhood is a common procedure. Long-term follow-up by paediatric cardiologists is variable. Identification and classification of postoperative complications may enable targeted follow-up and timelier discharges. This study aimed to characterize complication rates and assess discharge timing.
Methods:
This is a single-centre retrospective study of paediatric patients (aged 0-15 years) who underwent a transcutaneous closure of a PDA between January 2006 and December 2015.
Results:
A total of 156 patients who underwent interventional occlusion of a PDA were included. Complications were seen in 18 of 156 (12%) patients. High-grade complications occurred in 8 of 156 (5.1%) patients; these included device embolization, failure requiring surgical closure, or repeated interventional closure. Moderate to low-grade complications including flow acceleration in the aorta and left pulmonary artery (LPA) occurred in 10 of 156 (6.4%) patients. Fourteen of 18 (77%) complications were immediately apparent. Late mild to moderate obstruction of the descending aorta or LPA occurred in 3 of 156 (2%) patients. Later obstruction occurred in the Amplatzer ductal occluder 1 (ADO1) group only with large (4.5-5 mm) ducts. The average follow-up time for all patients was 81 (±47) months. Younger age at insertion and larger size of ADO1 devices were associated with later obstruction.
Conclusions:
In our cohort, PDA occlusion was associated with a 5.1% major complication rate, which is evident within 24 hours; a further 2% (all treated with ADO1 devices) developed between mild and moderate aortic or LPA obstruction at least 1 year after the procedure. To date, this has not required intervention. It may therefore be prudent to continue longer-term surveillance of patients who have undergone PDA occlusion with the ADO1 device.
