Objective: To evaluate the efficacy of transcatheter closure of patent ductus arteriosus (PDA) in infants and young children. Methods: From December 1998 to December 2001, 16 infants and toddlers were treated with catheterization, including 6 males and 10 females, ranging in age from 8 to 36 months (average, 17.8 ± 5.6) months. Weight 6.5 ~ 15kg, the average (11.5 ± 2 .3) kg. There were 9 cases of type A1, 5 cases of type A2, 1 case of type B2 and 1 case of type C; Qp / Qs1.4-5.7, mean 2.6 ± 1.0; aortography showed the narrowest diameter of PDA was 1.3-10. 8mm, average (4.3 ± 2.5mm). Results: In 16 cases, 3 cases were treated with coil, 13 cases were closed with mushroom umbrella, and the success rate was 10%. Postoperative cardiovascular angiography showed no residual shunt in the coil group. 38% 13) A very small amount of residual shunt was seen. A small amount of residual shunt was observed in 2 cases after 24 h of postoperative Hypersensitivity. A small amount of residual shunt was observed in 1 case after color Doppler ultrasound examination in January. The hospitalization days were 4 to 27 days with an average of (9.8 ± 5 .3) d; the number of days of postoperative hospital stay was 2 ~ 9 days, with an average of (4.3 ± 1.8) days. No serious complications occurred. Conclusion: Transcatheter closure of infant PDA is safe, simple, effective and rapid. It is worth popularizing and applying.
