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.
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.
TEE showed stent graft configuration and presence of leakage in all cases. In three cases, additional stent graft placement or bypass was performed.
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.
降主动脉支架植入术是开放性修复术的一种有前景的替代方法。经食管超声心动图（TEE）是一种用于主动脉疾病的敏感成像方式。我们回顾了我们在降主动脉支架植入术中应用TEE的经验。
5例患者在全身麻醉下接受降主动脉支架植入术。术中血管造影和TEE用于确定动脉瘤的范围和支架的放置位置。
TEE在所有病例中均显示了支架的形态和有无渗漏。3例患者进行了额外的支架植入或旁路手术。
TEE在提高支架定位准确性方面获得了有用信息，这可能改善治疗结果。TEE可通过确认主动脉病变、确定腔内移植物放置位置、评估动脉瘤囊隔离是否充分、有无渗漏以及术中动态心脏功能来促进修复。
