Penetrating Aortic Ulcers – Casuistry of Endovascular Therapy

We report our experience with two cases of endovascular treatment of penetrating aortic ulcers (PAU). The first patient was a 71-year-old woman with 30 mm width aortic ulcer accompanied by intramural hematoma of the descending thoracic aorta. The second patient was an 80-year-old obese woman with 50 mm pseudoaneurysma of the abdominal aorta, which was result of PAU. Both patients were successfully treated by means of tubular stentgraft, implanted from surgical cut down of the right femoral artery. Penetrating aortic ulcer represents localized, potentially lethal pathology of the aorta. Together with dissection and intramural hematoma belongs among the acute aortic syndromes. During nature course PAU can progress to the acute classic dissection, pseudoaneurysma or rupture of the aorta. It is principally disease of elderly hypertensive patients. Early diagnosis and appropriate therapy improves prognosis of patients with PAU. Open surgical repair with synthetic graft has been the gold standard of treatment but endovascular therapy is an attractive option in risk elderly patients. It seems to be a safe, effective treatment but stability of results of this method should be proved.
