Safety and efficacy of percutaneous patent ductus arteriosus closure via femoral vein under transesophageal echocardiography guidance / 中华实用儿科临床杂志

ABSTRACT

Objective To investigate the efficacy and safety of percutaneous patent ductus arteriosus (PDA) closure via femoral vein solely under transesophageal echocardiography guidance.Methods From May 2014 to May 2015,28 patients(13 boys,15 girls) were selected in Dalian Children's Hospital Affiliated to Dalian Medical University with PDA closure via the femoral vein under transesophageal echocardiography guidance,with mean age (3.5 ± 2.6)years and mean body weight (16.0 ± 6.5) kg.The mean diameter of PDA was (7.1 ± 3.9) mm.Patients were all treated by percutaneous PDA closure solely by transesophageal echocardiography via the femoral vein.The effect of the procedures was evaluated by echocardiography.The transthoracic echocardiography,chest X-ray film,cardiogram at 1 month,3 months and 6 months after procedure were followed up.Results Twenty-seven cases were successfully treated with percutaneous PDA closure via the femoral vein solely under transesophageal echocardiography guidance,while 1 patient was closed by surgical closure with on-pump beating-heart because PDA occluder strayed into the left pulmonary artery on 1-month follow-up.The procedural time was (48.5 ±8.7) min.The mean diameter of PDA occluder was (8.2 ± 4.1) mm.Twenty-seven patients survived without peripheral vascular injury or complications such as residual shunt,arrhythmia and cardiac perforation.One patient was transformed to surgical closure.Hospitalization time was (2.5 ± 0.5) days.At one month follow-up,no complications such as residual shunt or pericardial effusion occurred.Conclusion Transesophageal echocardiography guided percutaneous PDA closure via the femoral vein approach is safe and effective without the damage from radiation and contrast agents,and aviods the use of femoral artery puncture.
