Transcatheter coil occlusion of the small patent ductus arteriosus (<4 mm): improved results with a "multiple coil-no residual shunt" strategy.
We report our experience with transcatheter occlusion of the small PDA using Gianturco coils comparing a single coil strategy to a "multiple coil-no residual shunt strategy". Fifteen patients (Group I) had a single coil only placed irrespective of residual shunting and 20 (Group II) were treated using the no residual shunt strategy. Age, minimal PDA diameter, PDA length and PDA types were similar between groups. Closure rates in Group I patients were 60%, 80% and 87% at <1 month, 6 months and 1 year, respectively. In Group II, the <1 month and 6 month closure rates were 100%. The costs and hospital charges for coil closure were comparable to a concurrent surgical group; the total charges (hospital plus physician) were less for Group I, but similar between Group II and the surgical group. The complication rate for coil closure was significantly less than surgical closure. From these data, transcatheter closure with multiple coils can achieve the same closure rate as surgery at similar hospital charges with fewer complications.
