Short-, medium- and long-term results of percutaneous closure of patent ductus arteriosus

Background The persistent ductus arteriosus remains a common congenital pathology. The percutaneous closure has become the main technique for the closure of patent ductus arteriosus. Purpose Evaluate the short-, medium- and long-term results of percutaneous closure of patent ductus arteriosus, performed in Cardiology department of Sahloul University Hospital. Methods Children and adults who underwent percutaneous closure of patent ductus arteriosus in Cardiology department of Sahloul University Hospital, during 13 years between September 2003 and June 2016 were retrospectively included. We studied procedure's Results success rate, type of device, residual shunting, and adverse effects. Results One hundred and fifty-three procedures were realized during the study period. Patient's mean age at the time of procedure was 73.68 months (3 months to 53 years) and the sex ratio was 1.8 female for 1 male. The main circumstance for discovery was dyspnea (56.86%). The average echocardiographic persistent ductus arteriosus diameter was 4.7 mm. The average angiographic persistent ductus arteriosus diameter was 8.7 mm. Ninety-seven patients (63.4%), had a channel A-type, 30 patients (19.6%) had C type and 22 patients (17%) had E type on the Krichenko classification. A device was implanted in 140 cases (91.5%): 8 coils, and 132 Amplatz® devices. The failure rate of the procedure was 2.77%. The complications occurred in 11 patients (7.18%): 3 cases of immediate embolization, 3 cases of pulmonary protrusion, one case of inguinal hematoma and 4 cases of aortic protrusion with risk of aortic subocclusion in one of them. The device was removed immediately in this case. After a device was installed, complete occlusion was obtained in 85.8% at day 1, 90% at a month and 100% at 12 months. The average duration of the procedure 54 min (30 to 121 min). Conclusion Patent ductus arteriosus percutaneous closure gives good results with a low rate of complication.
