Methods Forty-nine consecutive patients with aortic aneurysm detected by 320-slice dynamic volume CT from April, 2011 to March, 2014 in our hospital were recruited in this study. The CTA characteristics of the aortic aneurysm were recorded. The correlation between the intraluminal thrombosis and the location as well as the shape of the aortic aneurysm were analyzed. Results There were 49 patients with aortic aneurysm (23 in the ascending aorta, 2 in the descending aorta and 24 in the abdominal aorta). The size and extent of the aneurysm were (5.68±1.49)cm
