Thoracic aortic thrombi are a well-known cause of distal embolic phenomena. There is a paucity of case reports because of the rarity of this condition, and thus clear management guidelines are lacking. The authors present a case of a mobile thoracic aortic thrombus managed by a surgical approach. This report demonstrates how intraoperative transesophageal echocardiography (TEE) proved to be critical in guiding surgical management. The utility of TEE in the diagnosis and management of aortic thrombi is also discussed. In addition, currently reported management strategies for this complex condition are reviewed.

Transesophageal echocardiography (TEE) has gained increasing popularity in the operating room and intensive care settings. The use of TEE can often times diagnose pathology that is missed by transthoracic echocardiography (TTE); in addition, it can be used as a guide to continuously monitor a patient's hemodynamics, along with observing the direct cardiac effects of fluid and vasopressor therapy. We present a case of acute fulminant hepatic failure in the ICU, where TEE allowed a rapid diagnosis. We performed prolonged TEE monitoring (72 hours) of the patient to monitor the patient's response to therapeutic interventions. We also discuss the diagnostic and therapeutic implications of prolonged TEE placement in the ICU. In addition, particular strategies to optimize the benefit and minimize the risk of this exciting, yet underutilized, technology are discussed.
