Fontan Failure and Thrombosis of Total Cavo-Pulmonary Connection Conduit

The immediate postoperative period of Fontan operation is frequently complicated by hemodynamic instability, sometimes requiring fenestration of the conduit. Thrombosis of total cavo-pulmonary connection conduit warrants early intervention to prevent systemic and pulmonary embolism. We report a case of Fontan failure requiring fenestration; which was further complicated by thrombosis of total cavo-pulmonary connection conduit and managed with anticoagulants.
