Abstract:
Objective To evaluate the effect of self-expandable occluder on closure of patent ductus arteriosus(PDA)with severe pulmonary arterial hypertension(PH)in adults.Methods Twenty-eight adult patients underwent transcatheter closure of PDA at a mean age of(31.3?11.6)years [(18—58)years].Either Amplatzer duct occluder or domestic device was used in the present study.X-ray,EKG and UCG were repeated in one day,one month,three months,and six months.Results Twenty of the 28 patients had successful occlusion,and the other 8 patients were given up.In the successful group,the narrowest diameter of PDA was(10.4?2.7)mm [(6—16)mm],the diameter of selected occluder was(15.6?3.2)mm [(10—20)mm] at the end of pulmonary artery.Systemic artery oxygen saturation(SAsat)before and after oxygen inhalation was(93.5?1.8)%,(98.2?1.8)%,respectively(P
