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
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.
