title: Endovascular stent: grafting in penetrating atherosclerotic ulcer of the thoracic aorta.
abstract: The aim of our study is the presentation of some interesting images of a case with symptomatic penetrating atherosclerotic ulcer (PAU) of the thoracic aorta and its endovascular treatment. Penetrating atherosclerotic ulcer is an ulcerating atherosclerotic lesion that penetrates the elastic lamina and is correlated with intramural hematoma (IMH) formation into the media layer of the aortic wall. PAU is more common in the elderly with severe atherosclerosis, hypertension, and hyperlipidemia. Transesophageal echocardiography, computed tomography, and magnetic resonance imaging are the common diagnostic tools. Surgical treatment may become necessary in cases involving the ascending aorta or in cases of intramural haematoma formation. In the era of minimally invasive surgery stent-grafting is indicated mainly in the elderly patients in presence of serious co-morbidities.
