Background: The purpose of this study was to examine the accuracy of diagnostic methods in the preoperative evaluation of abdominal aortic aneurysm before endovascular treatment. Material/Methods: During the period of January 2002-December 2004, 67 patients with AAA (42 diagnosed in the Department of Radiology of the Central Clinical Hospital of the Ministry of Internal Affairs and Administration and 25 patients diagnosed the in the Department of Radiology of Medical Academy in Bialystok) underwent ultrasonography, spiral CT with 3D reconstructions (3D CTA), and digital subtraction angiography (DSA) following treatment of aortoiliac aneurysms with endoluminal stentgrafts in 36 and 12 patients, respectively. Results/Conclusions: Our experience suggests that spiral computerized tomographic angiography with three-dimensional reconstruction (3D CTA) is a reliable, relatively noninvasive technique to assess the feasibility of endovascular aneurysm repair. DSA allows verification of the measurements from spiral computed scans, but it is a more invasive method than CTA. However, CTA with 3D reconstruction shows a diagnostic effectiveness similar to that of DSA. Thus it may be sufficient as a preoperative imaging technique when evaluating a patient for an endovascular graft procedure.
