Unintended Consequences of Innominate Artery Cannulation in a Pediatric Patient: Infection of Innominate Artery Graft Stump With Subsequent Formation of Right Common Carotid Artery Pseudoaneurysm.

Abstract

Indirect arterial cannulation techniques, such as cannulation of the innominate artery (IA) using an end-to-side anastomosed vascular graft, are commonly used to establish cardiopulmonary bypass in congenital cardiac surgery. Although rare, unintended consequences, such as graft infection, may occur. We describe a case of IA graft infection with subsequent pseudoaneurysm formation in a 10-year-old child who underwent multiple procedures for Tetralogy of Fallot with absent pulmonary valve syndrome.
