Materials and Methods: This was a prospective study involving 30 patients who had undergone endovascular repair of infrarenal aortoiliac aneurysms. Duplex ultrasound and CT angiography were performed simultaneously by independent radiologists. Measurements of the aneurysm sac diameter were assessed, and the presence or absence of endoleaks was determined.  Results: The average diameter of the aneurysm sac, as determined by duplex ultrasound and CT angiography was 6.09 \u00b1 1.95 and 6.27 \u00b1 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p &lt; 0.01). Comparing the duplex ultrasound and CT angiography results regarding the detection of endoleaks, we found that the former had a negative predictive value of 92.59% and a specificity of 96.15%.  Conclusion: Our results show that there is little variation between the two methods evaluated, and that the choice between the two would have no significant effect on clinical management. Duplex ultrasound could replace CT angiography in the postoperative follow-up of endovascular aneurysm repair of the infrarenal aorta, because it is a low-cost procedure without the potential clinical complications related to the use of iodinated contrast and exposure to radiation.<\/jats:p>","DOI":"10.1590\/0100-3984.2014.0139","type":"journal-article","created":{"date-parts":[[2016,9,10]],"date-time":"2016-09-10T17:20:47Z","timestamp":1473528047000},"page":"229-233","source":"Crossref","is-referenced-by-count":6,"title":["Duplex
