Preoperative imaging of aortic aneurysms. Conventional and digital subtraction angiography, computed tomography scanning, and magnetic resonance imaging

Aneurysm imaging is important in deciding on the timing of and operative approach for aneurysmorrhaphy. Various noninvasive and invasive imaging techniques are available for the anatomic definition of abdominal aortic aneurysms, involvement of adjacent structures, and intra-abdominal pathology. Careful preoperative evaluation can avert hemorrhagic, embolic, and ischemic complications of elective aneurysm repair.
