Abstract
Percutaneous closure of patent ductus arteriosus (PDA) is a wellknown technique and is the first choice for this condition.
Objective: To report our pioneer experience in the region, the first 6 percutaneously treated PDA cases. The smallest diameter was less than 3 mm and they were closed using transcatheter technique with controlled-release coils in Las Higueras Hospital, Talcahuano.
Patients and Methods: Between December, 2010 and September, 2011, six female patients carrying PDA were treated via interventional catheterization. Three presented a type A1 from Krichenko ductus arteriosus, two patients of the type A2 and one patient of the type E. Under general anesthesia, cardiac catheterization was performed via the femoral artery and aorto-graphy. The ductus was reached using a multipurpose catheter and through this, the coil was inserted closing the abnormality from the pulmonary to the aortic end using the controlled-release coil.
Results: All patients achieved angiographic ductal closure without residual shunt before discharge. The procedure lasted an average of 55 minutes, the mean fluoroscopy time was 14 minutes and there were no complications. Patients were discharged the day after surgery after undergoing chest radiography and echocardiography. In later follow-ups, patients were asymptomatic.
Conclusion: The closure of percutaneous PDAs is an effective, safe and less invasive technique, which has been performed for some time in Santiago, with this being the first regional report.
