Objective: To evaluate the safty
and efficiency of transcatheter closure patent ductus arteriosus (PDA)
using modified Amplatzer occluder device in children.
Methods: 14 children (4 male,10
female) with PDA were performed the transcatheter closure from June 2000 to
Feb. 2001. Age was 1-13 years old, and mean age 4.8 years. The
narrowest diameters of PDA were from 2.8mm to 8.0mm respectively. The
modified Amplazer occluder device was transmitted through femoral vein.
Aortographies were performed immediately after the procedure.
Results: No
residual shunt in the 10 patients, the Echo showed the heart recovered to
normal size. 3 cases showed small residual shunt, 2 days later, the
residual shunt stopped. The largest PDA aortographies showed moderate
residual shunt, but 2 days later, the residual shunt became small and
stopped in 3 months. The UCG showed the left ventricle was smaller than
before the procedure.
Conclusions: Transcatheter closure
of moderate to large PDA using Amplatzer occluder device was a safe,
efficient method.
