Abstract :

Aim. Peripheral arterial disease (PAD) is indication of systemic atherosclerosis that give rise to significant stenosis of the out of the distal aortic arch arteries. Doppler Ultrasonography (US), magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are noninvasive methods and frequently used for determining to the lesion location. Contrast arteriography is a method to localized exact vessel pathology before intervention.With the enhance of multidetector technology, CTA sit in conventional angiography.The aim of study is that lower extremity PAD with cases, the evaluation of the diagnostic value of Doppler US with the findings of CTA. Method. 45 patients were included with the PAD findings in this study. There were 35 (77.8%) intermitten claudication, 7 (15.5%) rest pain and 3 (6.7%) ischemic ulseration of the patients. Each leg divided into 7 arterial segments, 630 arterial segments as 90 leg of the 45 patients were evaluated with CTA and Doppler US. Each of the patients were performed before Doppler US after CTA within the same day then were evaluated Doppler US and CT angiography results. Doppler US findings were evaluated in according to the degree of stenosis determined by CTA. Results. This study completed forty- five patients (32 males 13 females; mean age 53.8±4.8). We found significantly higher that have percentage of the pathologic segments of the femoropopliteal artery as to the other vessels (p 0.05). There was no significant difference that between percentages possession of pathologic segments of the studied other vessels (p 0.05). The majority of cases (85%) had normal vessel diamater and peak systolic velocity ratio (PSVR) was found 1 in 98.1% of cases and non pulsed was found in 6.4 %. Although being vessel complete ocluded in 7.3% of cases, PSVR was found 1 in 0.85% of this cases and there were no pulsed in 85,1%.Conclusion. Generally gives to notably parallel results with CTA findings which Doppler US is a successful modality for the evaluation of PAD cases.
