- Abstract
Background: Stent graft implantation for thoracic descending aorta is a promising alternative to open repair. Transesophageal echocardiography (TEE) is a sensitive imaging modality for aortic disease. We reviewed our experience with TEE in stent graft implantation for thoracic descending aorta., Method: Five patients underwent stent graft implantation for thoracic descending aorta under general anesthesia. Intraoperative angiography and TEE were used to identify the extent of the aneurysm and the placement of the stent., Results: TEE showed stent graft configuration and presence of leakage in all cases. In three cases, additional stent graft placement or bypass was performed., Conclusions: Useful information was obtained by TEE in enhancing the accuracy of stent graft positioning potentially improving outcomes. TEE may facilitate repair by confirming aortic pathology, identifying endograft placement, and assessing the adequacy of aneurysm sack isolation, presence of leakage, as well as dynamic intraoperative cardiac performance.
