Comprehensive Analysis of Invasive and Noninvasive Investigation Methods in Peripheral Artery Disease

Peripheral artery disease of the lower limbs is, in fact, an arterial pathology, by which the blood flow is reduced, due to the obstruction caused by the deposit of atheroma plaques.(1) This deposition occurs slowly, which leads to a slow progression of the disease, and thus, at the onset of symptomatology. The objective of the study was to make a comparison between the invasive and noninvasive paraclinical investigations performed in patients with peripheral arterial disease of the lower limbs in the E.C.C.H. Sibiu. In conclusion, between the two investigations (computed tomography angiography and digital subtraction angiography) there are no noticeable differences in the terminal aorta and iliac arteries, but in reducing the arteries calibre, the use of digital subtraction angiography is preferred, according to our study, although it is more invasive and exposed to complications.
