Use of multi-detector CT angiography in identification and classification of aorto-iliac diseases; clinical and surgical application

To evaluate role of multi-detector CT angiography in assessment of various aorto-iliac diseases and display golden clinical application comparative with other imaging methods. Thirty patients with manifestation of aorto-iliac diseases underwent CT angiography of the abdominal aorta and iliac vessels for disease evaluation and further treatment planning. On the basis of CT angiographic findings, the study shows prevalence of atherosclerosis varying from small plaques to occlusion as seen in leriche syndrome. Hypertension and diabetes mellitus were the most risk factors. The most common symptoms were lower limb claudication and burning pain. Most aneurysms are seen infra-renal with the predominant size is of 5–7cm, most aneurysms starts thoracically and shows intramural thrombus. MDCT angiography is excellent noninvasive scanning technique for patients suspected of having aorto-iliac occlusive disease, with higher spatial resolution and faster acquisition times, allowing assessment of the aorta and its branches with greater accuracy than other modalities.
