Abstract:
In the first case, a 60-year-old man was referred to our hospital for a sudden stomachache. A computed tomography scan revealed a thrombus at ascending aorta with acute mesenteric ischemia. In the second case, a 62-year old man developed a hypoglycemic attack with unbalanced diet. A computed tomography showed a thrombus at ascending aorta without thromboembolism. Laboratory data of both cases showed elevated platelet and a loss of antithrombin III. We administered a resection of thrombus to prevent a systemic embolism. We suggested that the risk of ascending aorta thrombus was elevated platelet and a loss of antithrombin III.
