Abstract Objective: To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. 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 ± 1.95 and 6.27 ± 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p < 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.

Purpose: To report the results of a multicenter feasibility study of the Jostent balloon-expandable stent-graft in the treatment of renal and iliac artery lesions. Methods: Twenty-three patients (17 men; mean age 62 years, range 38–80) with lesions in the renal (n = 12) or iliac arteries (n = 12) were enrolled in 6 centers over a 1-year period. Preprocedural computed tomography (CT) and angiography were performed in all patients. The Jostent device was implanted in the 24 arteries to treat 11 in-stent stenoses, 2 arterial ruptures, 2 aneurysms, 2 dissections, 2 ulcerated stenoses, and 5 chronic occlusions. Follow-up included color duplex ultrasound examination on the day after the procedure and at 6 months; patients with renal artery stent-grafts were also evaluated with CT angiography. Results: Twenty-seven stent-grafts were deployed successfully in the 24 (100%) arteries. Seven (30%) patients required adjunctive procedures to address 1 acute in-stent thrombosis, 2 dissections, and 4 in-stent residual stenoses. At 6-month follow-up, 2 (8.3%) restenoses occurred in the renal arteries; these were treated successfully using balloon angioplasty. Conclusions: These data suggest that a balloon-expandable stent-graft may be safe and useful in patients with selected peripheral indications.
