Abstract: Objective:To investigate the safety and efficacy of percutaneous patent ductus arteriosus(PDA) occlusion for ambulatory surgery.Methods:102 cases of ambulatory surgery and 83 cases of nonambulatory surgery for transcatheter PDA occlusion under fluoroscopy were selected from the Department of Cardiovascular Surgery,Xijing Hospital of Air Force Medical University from June 2017 to June 2018.Echocardiographic data of the immediate,1month and 6month followup after surgery was collected to compare the clinical outcomes and hospitalization costs between the two groups.Results:Ductus arteriosus of the patients in both groups was successfully occluded.There was no significant difference in operative time and occluder diameter between the two groups.Complications such as residual leakage,hemolysis,and peripheral vascular injury showed no significant difference between the two groups.The total hospitalization cost and hospitalization days in the ambulatory surgery group were significantly lower than those in the nonambulatory surgery group(P<0.05).Conclusion:Shortterm clinical outcomes of percutaneous patent ductus arteriosus occlusion for ambulatory surgery are safe and effective,with significantly reducing days and costs of the hospitalization.
