Simulatneous delivery of two patent arterial duct coils via one venous sheath

摘要

A female child, 10 months of age, weigh- ing 7·2 kg, was catheterised for closure of a patent arterial duct. Aortography was performed in the lateral projection and the minimum diameter of the arterial duct was assessed by comparing it to the size of the catheter. The duct size was estimated between 3 and 3·5 mm at the narrowest point, therefore, it was decided to deliver two 5 mm patent arterial duct coils to avoid placement of an 8 mm coil in this small child. Similar operations were subsequently performed in two fur- ther children.
