[Thrombosis of an apparently normal thoracic aorta and arterial embolism].

With the advent of new imaging techniques, the aorta has been increasingly identified as a source of arterial embolism. The majority of thrombi occur in aneurysms or are adherent to atherosclerotic lesions in the abdominal aorta. Thrombi in the thoracic aorta are much less common, particularly in apparently normal aortas. Consequently, the natural history and optimal treatment of these lesions are not well-defined. The aim of this article was to describe the clinical characteristics, treatment, and outcome in three patients with thoracic aorta thrombosis and arterial embolism. Currently available literature on this pathology is reviewed and the differential diagnosis of these lesions is discussed.
