Transcatheter coil occlusion of hepatic arteriovenous malformation in a neonate.

A 3-day-old neonate was diagnosed to have severe congestive heart failure due to a large shunt through a hepatic arteriovenous malformation. Percutaneous transcatheter delivery of two detachable coils resulted in complete abolition of the shunt. The patient showed dramatic clinical improvement and resolution of the heart failure, which was sustained on follow-up. This case represents a novel use of detachable occluding spring coils designed primarily for occluding patent ductus arteriosus.
