[Multispiral computed tomography-assisted angiography in diagnosis of diseases of the aorta and lower limb arteries].
OBJECTIVE
Our work was aimed at determining the diagnostic value of multislice computed tomography-assisted angiography in atherosclerotic lesions of the aorta and arteries of the lower limbs, taking into consideration the condition of the peripheral bed, as well as at making an angiographic assessment of the quality of the reconstructive operations performed.


METHODS
Over the period from October 2005 to July 2006, multispiral computed tomography-assisted angiography (hereinafter referred to as MSCTA) followed by an operative intervention was carried out in a total of 59 patients who were diagnosed with diseases of the aorta and arteries of the lower extremities. The average age of the patients was 59.1 years (range from 17 to 83 years). MSCTA was carried out using a 16-slice CT scanner (Somatom Sensation Cardiac 16, <<Siemens>>) during the arterial phase of injecting the non-ionic radiopaque material <<Ultravist>> (<<Schering>>, Germany).


RESULTS
Studying the dissemination of the obliterating processes revealed an aneurysm of the abdominal portion of the aorta (n=10), while in the remaining cases atherosclerotic lesions were observed to be localized in the aorto-femoral (n=17) and femoropopliteal segments (n=32). Comparing the findings obtained by the comprehensive examination and analysis of the angiograms, we determined that the sensitivity, specificity and accuracy of MSCTA in the mentioned groups amounted to 96%, 92% and 94%, respectively.


CONCLUSIONS
MSCTA performed using the novel software appears to be an alternative to other diagnostic methods of examining patients presenting with occlusive diseases of the lower limb arteries.
