摘要
Aortic dissection occurs when layers of the aortic ,walls are separated by the blood flow through an intimal tear. Dissection of the aorta most frequently originates in the ascending aorta （70%）, followed by the descending aorta （22%）, the aortic arch （7%） and the abdominal aorta （1/%）.1 The dissection limited to the abdominal aorta is rare.2 An isolated abdominal aortic dissection （IAAD） concomitant with an abdominal aortic aneurysm （AAA） is uncommon. We present here one patient with IAAD and AAA treated by endovascular therapy.
