stent graft placed in the<unk>  aorta to treat a<unk> . The size cut off for aortic aneurysm is crucial to its treatment. A<unk>  aorta greater than 4.5 cm is generally defined as aneurysmal, while a size greater than 6 cm is the distinction for treatment, which can be either endovascular or surgical, with the former reserved for pathology at the descending aorta. Indication for surgery may depend upon the size of the aneurysm. Aneurysms in the ascending aorta may require surgery at a smaller size than aneurysms in the descending aorta. Treatment may be via open or via endovascular means.
