Aims Thoracic endovascular aortic repair (TEVAR) is commonly considered as a valid alternative to surgery. Endoleaks occurrence is one of the principal limitations of TEVAR.

Methods and results Fifty-four patients with thoracic aortic disease suitable for TEVAR were prospectively enrolled in the study. After stent placement, the result of the procedure was assessed by ANGIO, TEE, and cTEE. The use of contrast (Sonovue, Bracco) significantly improved TEE quality (P = 0.0001). cTEE was superior in entry tears, false and true lumen and aneurysm thrombosis identification, and microtears and ulcer-like projections detection before stent deployment. After stent deployment, cTEE was more accurate than TEE and ANGIO in the detection of slow flow in the false lumen and in the aneurismal sac (P = 0.0001), and in the remaining flow identification (P = 0.0001). Notably, cTEE is more accurate in the endoleaks detection (P = 0.0001) and in the incomplete stent expansion diagnosis and need for a further balloon inflation (P 0.002), or a further stent implantation (P 0.006), compared with TEE and ANGIO.

Abstract

Aims Thoracic endovascular aortic repair (TEVAR) is commonly considered as a valid alternative to surgery. Endoleaks occurrence is one of the principal limitations of TEVAR. Transoesophageal echocardiography (TEE) is often adopted in adjunct to fluoroscopy and angiography (ANGIO) during stent-graft implantation. In the present study, we compare intraprocedural ANGIO, TEE, and contrast-enhanced TEE (cTEE), and we also evaluate their accuracy in early endoleaks detection and characterization. Methods and results Fifty-four patients with thoracic aortic disease suitable for TEVAR were prospectively enrolled in the study. After stent placement, the result of the procedure was assessed by ANGIO, TEE, and cTEE. The use of contrast (Sonovue, Bracco) significantly improved TEE quality (P = 0.0001). cTEE was superior in entry tears, false and true lumen and aneurysm thrombosis identification, and microtears and ulcer-like projections detection before stent deployment. After stent deployment, cTEE was more accurate than TEE and ANGIO in the detection of slow flow in the false lumen and in the aneurismal sac (P = 0.0001), and in the remaining flow identification (P = 0.0001).
