A 54-year-old man experienced acute leg artery blockage due to a floating thrombus from his aorta. Surgical removal confirmed the non-malignant thrombus, highlighting TEE
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Diagnostic Imaging
Background:
- Floating thrombi in the thoracic aorta are rare, often associated with significant morbidity.
- Acute arterial occlusion necessitates prompt diagnosis and intervention.
Observation:
- A 54-year-old male presented with acute left leg arterial occlusion.
- Imaging revealed two masses in an otherwise normal thoracic aorta post-embolectomy.
- Histology of embolus suggested thrombus, but malignancy was considered.
Findings:
- Anticoagulant therapy did not reduce mass size.
- Surgical extirpation under cardiopulmonary bypass and TEE guidance was performed.
- Frozen section confirmed the masses were non-malignant thrombi.
Implications:
- Transesophageal echocardiography (TEE) is crucial for diagnosis and surgical planning in aortic thrombus cases.
- Surgical intervention may be necessary when conservative management fails.
- The optimal treatment strategy for aortic thrombi requires further investigation.
