Nonsurgical Management of a Congenital Aortocaval Fistula from Right Subclavian Artery to Superior Vena Cava Along with SVC Obstruction

摘要

Congenital arteriovenous malformations between the subclavian artery and the superior vena cava (SVC) is a very rare anomaly scantily described in the literature. We describe this anomaly in a 4-month-old infant who presented with congestive heart failure. He was diagnosed to have a right subclavian artery to SVC fistula associated with SVC stenosis .The child successfully underwent device (vascular plug) closure of the fistula and SVC stenting. Six months postprocedure, child is doing well, with complete resolution of symptoms.
