[Overall experience with percutaneous occlusion of patent ductus arteriosus].
OBJECTIVE
To evaluate the overall experience of our institution with percutaneous occlusion of the patent ductus arteriosus.


METHODS
Since December/92, 150 patients underwent 178 procedures (85-Rashkind technique; 87-Gianturco coils; 6-Duct Occlud). Median age was 6.5 years (1 to 57). Mean minimum ductal diameter was 3.05 +/- 1.24 mm (1 to 8). Clinical and echocardiographic evaluations were performed periodically.


RESULTS
Adequate implantation was achieved in 143 (95.3%) patients. Prevalence of immediate residual shunting was 52.1%, falling to 15.9% during follow-up. This figure decreased to 5.2% after new additional procedures. Umbrella and coil embolization occurred in 1 and 12 procedures, respectively. Hemolysis and mild stenosis of left pulmonary artery were observed in one patient each. There was no mortality.


CONCLUSIONS
This therapeutic modality is safe and efficacious with good follow-up results.
