Use of platinum microcoils to embolize vascular abnormalities in children with congenital heart disease.

Many vascular anomalies found in children with congenital heart disease can be embolized with catheter-delivered steel coils. Platinum microcoils delivered through a microcatheter broaden the spectrum of lesions amenable to transcatheter closure. Platinum microcoil delivery technique is described, and representative cases demonstrating microcoil utility and benefits are presented.
