Abstract
- Penetrating atherosclerotic ulcer (PAU) of the aorta are increasingly recognized as a distinct disease entity. PAU of the aorta is defined as atheromatous lesion of aorta with ulceration that penetrates the internal elastic lamina, allowing hematoma formation in the media. They are most commonly located in the distal descending aorta and tender to occur in elderly patient with hypertension and a history of cardiac disease (1). Although their natural history remains ill-defined, such ulcers may lead to pseudoaneurysm formation, dissection, rupture, or embolization (1-3). Because PAU is much less common than classic aortic dissection, it may not be recognized and therefore may be misclassified as aortic dissection at presentation. We experienced one case of successful surgical repair of PAU that previously misdiagnosed to aortic dissection.
