Abstract
79-year-old man had a right abdominal pain. He underwent computed tomography (CT), which revealed a filling defect in the thoracic descending aorta. It caused major embolic complication, right renal infarction and superior mesenteric artery embolism. He was referred to our hospital. In addition, enhanced magnetic resonance imaging revealed a mass with ringed enhancement. Angiography showed a filling defect in the Th10 level. It is difficult to differentiate from the malignant tumor. Urgent surgery was performed because of dangerous embolism. Aortic wall including mass was removed en bloc and replaced with prosthesis graft under partial cardiopulmonary bypass. The mass, 32 × 18 mm in diameter, was revealed thrombus material with no macroscopic sign of malignance. The postoperative course was good to take a Coumadin. No recurrence thrombosis has been observed for a year. We reported a good result of a surgical treatment for mobile thrombus in thoracic aorta.
