Abstract:
Objective To evaluate the clinical value of interventional therapy of patent ductus arteriosus(PDA).Methods A total of 941 patients(259 male and 682 female) with PDA admitted from March 1998 to August 2007,aged from 3 months to 74 years old(mean age 13.7?14.5 years old) were included in this study.The clinical characteristics and the outcomes of the therapy were retrospestively studied.Results These PDA types were classified according to Krichenko's classification by aortic angiography.Among all the patients,641 of then(68.1%) had type A PDA,11 patients(1.1%) had type B,202 patients(21.5%) had type C,8 patients(0.85%) had type D and 79 patients(8.4%) had type E PDA.The ranges for the minimun inner diameter of PDA was 1.2-1.5(4.6?2.9) mm,the inner diameter of aorta end was 2.0-32.7(11.1?5.7) mm,the length was 2-42.6(6.7?3.3) mm and the mean pulmonary arterial pressure was 9.7-106(34.7?19.4) mm Hg.Various occlusion devices were used to close the PDA including AGA mushroom occluder in 146 patients,AGA atrioseptal defect device in 2 patients,homemade PDA ductal occluders in 720 patients,homemade membranous ventricular septal defect device in 18 patients,homemade muscular ventricular septal defect device in 6 patients, eccentricity PDA devices in 18 patients and Germany pfm spring coil in 31 patients.Transcather closure was unsuccessful in 7 patietns and the success rate of operation was 99.3%(934/941).Conclusion Most patients can be cured by catheterization closure.To master procedural indication and accurate manipulation skill can reduce the procedural complications.The procedures should be handled carefully in infants or patients with pulmonary artery hypertension.The evaluation of pulmonary artery pressure is the key point prior to the interventional therapy.The experience on long-term efficacy of transcatheter PDA closure in patients complicated with pulmonary artery hypertension needs further exploration.
