Objectives: After studying the article entitled “Ultrasonographic Surveillance of Abdominal Aortic Endovascular Aneurysm Stent Graft Repair in a Dedicated Vascular Laboratory,” you will be able to:
Describe sonographic findings associated with aortic endograft endoleaks
Determine color and spectral Doppler settings appropriate for endoleak detection
Determine the accuracy of sonographic findings compared with computed tomographic angiography in the evaluation of aortic endografts
Approximately what percentage of women between 75 and 84 years of age have an aortic aneurysm measuring between 2.9 and 4.9 cm? 2% 4% 5% 6%
Between 2001 and 2006, the frequency of endovascular repair versus open repair of abdominal aortic aneurysms underwent what approximate change?
A 50% increase Doubled Tripled A four-fold increase
The most important predictor of complications in endovascular grafts for abdominal aortic aneurysm repair is
Heart disease Hypertension Original aneurysm size Growth in residual sac size
In what percentage of measurement pairs were the sonographic and computed tomographic residual sac size measurements an exact match?
5% 11% 25% 75%
In this study, approximately what percentage of patients were males?
25% 50% 75% 90%
For the true-positive sonographic examinations included in this analysis, what was the percentage agreement between computed tomography and sonography for the endoleak type?
67% 74% 86% 93%
What was the approximate average difference between all of the sonographic measurements and the CT measurements of residual sac size?
1 mm 2 mm 3 mm 4 mm
For the endoleak analysis in this study, what percentage of the cases were true positives?
9% 16% 26% 49%
In the present study, what percentage of the paired sonographic and computed tomographic scans were performed within 30 days of each other?
64% 71% 82% 93%
What was the overall accuracy of both the endoleak and residual sac size analyses?
67% 71% 75% 79%
