Transesophageal echo-guided endovascular exclusion of thoracic aortic mobile thrombi.

Mobile luminal thrombus of the descending thoracic aorta is an unusual finding in patients with peripheral embolization. The diagnosis is best made with transesophageal echography (TEE). Traditionally, systemic anticoagulation and selective surgical thrombectomy are standard treatment. We present a case report of recurrent mobile thrombus despite surgical thrombectomy and systemic anticoagulation. We treated it with endovascular exclusion of a descending thoracic aorta emboligenic lesion with an endoluminal stent graft, using simultaneous TEE and fluoroscopic intraoperative guidance. The patient remains symptom-free 9 months after stent-graft implantation. TEE-guided endoluminal exclusion should be considered in treatment of descending thoracic aorta emboligenic lesions.
