Computed tomography of aortoiliac atherosclerosis

|June 1, 1987
Summary
Computed tomography (CT) and angiography are compared for evaluating aortoiliac atherosclerotic peripheral vascular disease. Angiography excels in plaque morphology and iliac stenosis assessment, while CT better detects calcification and incidental findings.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Radiology
Background:
- Atherosclerotic peripheral vascular disease affects the aortoiliac segment.
- Accurate imaging is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To compare the diagnostic accuracy of computed tomography (CT) and angiography.
- To evaluate disease depiction in the aortoiliac segment.
Main Methods:
- Twenty-three patients with atherosclerotic peripheral vascular disease underwent both angiography and CT.
- Examinations focused on stenosis, plaque morphology, ectasia, calcification, and other pathologies.
Main Results:
- Angiography and CT showed equal accuracy for aortic stenosis/occlusion and aortic ectasia.
- Angiography was superior for aortic plaque morphology (57%) and iliac abnormalities (74%).
- CT better identified intimal calcification and incidental findings, including an aortic rupture.
Conclusions:
- CT complements angiography in evaluating aortoiliac disease but has limitations in tortuous or calcified iliac segments.
- CT cannot replace arteriography for atherosclerotic disease detection but aids in clarifying findings.
