Aortic thrombus after coil occlusion of a type E patent ductus arteriosus.

A 5-year-old girl was referred to our institution for closure of a silent patent ductus arteriosus. Cardiac catheterization revealed a tiny-to-small patent ductus arteriosus of the elongated, conical type (Type E). Coil occlusion was performed with a Gianturco coil, 0.035-4 cm(-3) mm. A follow-up echocardiogram showed a very small residual ductal shunt and a moderate-sized thrombus at the aortic end of the ductus arteriosus. The patient remained asymptomatic.
