Description
Summary:This study reports a case wherein a new thrombus was detected by transesophageal echocardiography in the conduit during extracardiac conduit Fontan procedure. Immediately after weaning from the cardiopulmonary bypass and administration of protamine, a thrombus was noted in the conduit by transesophageal echocardiography. Since the patient was hemodynamically stable, anticoagulation therapy was initiated after admission to the intensive care unit. One week post-surgery, imaging results showed residual thrombus, but the patient was safely discharged. Even during Fontan procedure, careful observation with transesophageal echocardiography is important because of the possibility of thrombus formation in the conduit.
