Aim. The aim of this study is to evaluate the accuracy of multidetector row CT angiography (MDCTA) of the abdominal aorta and lower extremities arteries in patients with peripheral arterial occlusive disease who did not receive any prior treatment whether interventional or surgical.
Methods. Twenty-two patients with peripheral vascular occlusive disease (16 male, 6 female, age range 44-85 years) underwent MDCTA of the abdominal aorta and lower extremities. Digital substraction angiography (DSA) of the same districts was performed within 3 months. Images were blindly interpreted by 2 interventional radiologists and compared with the results of digital subtraction angiography.
Results. Sensitivity and specificity of MDCTA were 92% and 94%, respectively, with positive and negative predictive values of 93% and 95%. Overall diagnostic accuracy was 93%. Normal arterial segments and 100% occlusions were correctly identified in all cases by MDCTA. Moderately stenotic segments interpretation in the calves appeared to be more controversial, but no statistical difference in accuracy in this district was noted with respect to accuracy in more proximal arteries.
Conclusion. MDCTA of the abdominal aorta and lower extremities is a feasible, accurate imaging modality in clinical practice when compared to DSA.
