Anaesthetic management of a patient undergoing reoperation for pathway obstruction after fontan operation

Since 1968, the Fontan operation, or its various modifications, have provided a functional correction in an increasingly complex spectrum of congenital heart malformations.1.2 These procedures have gained wide acceptance because of very good intermediate and longterm results2. However, as survival increases, follow up of these patients has shown more prevalent reoperations for obstruction of the surgically created corrective pathway.3 perioperative management of these patients requires an understanding of the unique anatomic and physiologic changes occurring in this condition. In this report, we review our anaesthetic management of a patient who underwent reoperation for thrombotic occlusion of the conduit from a previous Fontan procedure.
