Transcatheter occlusion of large pulmonary arteriovenous malformations using multiple devices in a neonate.

Pulmonary arteriovenous malformations (PAVMs) are usually well-tolerated hemodynamically. Rarely, they cause severe neonatal cyanosis, requiring urgent treatment. We report the use of multiple transcatheter vascular occlusion devices to reduce right-to-left shunting in a neonate with multiple, large PAVMs.

Transcatheter closure of patent ductus arteriosus and aorto-pulmonary vessels using non-ferromagnetic Inconel MReye embolization coils.

Objectives: We report the use of non-ferromagnetic embolization coils for transcatheter PDA closure.

Background: Transcatheter patent ductus arteriosus (PDA) closure has been performed for 40 years. A number of devices have been used with varying degrees of success.
