Pediatric interventional neuroradiology: “How I do it” vol. II—Embolization

Abstract

Pediatric arteriovenous shunts can be challenging to embolize and the consequences of excess venous penetration disastrous. Moreover, the congenital nature of most shunts necessitates neonatal intervention whenever (medically refractory) heart failure occurs. Here, we describe current endovascular treatment strategies based on personal experience and literature review. While disparate, arteriovenous malformation, dural arteriovenous fistula (AVF), pial AVF, and vein of Galen aneurysmal malformation share unifying features such as high output heart failure and venous hypertension. This tutorial is divided into passages on Goals, Access, and Treatment which respect differences among pediatric arteriovenous shunts while maintaining a narrative economy.
