“…14 A study by Singh et al 56 assessed the variability of ultrasonographic measurements at different levels of the abdominal aorta and concluded inexperienced sonographers might achieve acceptable performance given appropriate training and surveillance. All of the studies in this review reported limited experience with minimal training of the ED providers performing the bedside US, with favorable outcomes as well.…”

“…6,41,42 Singh et al assessed the variability of sonographic measurements at different levels of the abdominal aorta and concluded that inexperienced sonographers might achieve acceptable performance with appropriate training and surveillance. 43 Nguyen et al also further confirmed that novices could be trained to screen after 15 days. In the setting of technically difficult cases, continued quality improvement with scan experience was essential.…”

Abdominal aortic aneurysms (AAAs) occur when the aorta diameter is >3 cm (30 mm). Ruptured AAA has a high mortality rate. Ultrasound is the imaging modality of choice to screen for this vascular disease. There are many common errors and pitfalls in the acquisition and interpretation of ultrasound imaging of the abdominal aorta, such as measurement errors and variations in technique, misdiagnosis errors, difficulty with visualization of the aorta and a wide range of sonographer experience. We review the common errors and pitfalls to recognize and avoid in ultrasound imaging of the abdominal aorta.

“…However, there is a relatively higher rate of interobserver and intraobserver variability with ultrasonography than with angiotomography, 18 but this variability is no larger than 4 mm, on average. 19 Additionally, ultrasonography is also able to provide a better approximation to the true perpendicular diameter of an abdominal aortic aneurysm, since it is not affected by the angle of the aorta, which impacts on tomography results at angles greater than 25°. 20 Endoleaks can be detected by ultrasound using color spectral analysis to show blood flow.…”

Vascular ultrasonography for follow-up of endovascular repair of abdominal aorta aneurysms

et al. 2014

Background: There is little information available on follow-up of abdominal aortic aneurysm patients treated with endovascular repair using vascular ultrasonography in Brazil or on how it compares with the results of angiotomography. Since ultrasonography is an examination that is risk-free, inexpensive and widely available, it is a very attractive method. In this study we attempted to evaluate the sensitivity and specificity of vascular ultrasonography for follow-up of these patients by comparing the method with angiotomography. Materials and methods: We conducted a prospective study from June 2012 to May 2013. We examined patients followed-up at the endovascular surgery clinic run by the University Hospital of Londrina after endovascular repair of abdominal aortic aneurysms. All patients underwent angiotomography for follow-up and were also examined using simple abdominal X-rays and vascular ultrasonography. Results: A total of 30 patients were analyzed, with a mean age of 73 years and a mean aneurysm diameter of 6 cm. Four endoleaks were detected. Vascular ultrasonography achieved sensitivity of 75% and specificity of 96% for classification of these endoleaks, in comparison with angiotomography. Conclusions: Vascular ultrasonography is an excellent primary method for evaluation and post-surgical follow-up of patients treated with endovascular repair of abdominal aorta aneurysms. However, when ultrasonography detects problems or is difficult to accomplish, it should be supplemented with a more specific investigation for diagnostic confirmation.

Intra- and interobserver variability in ultrasound measurements of abdominal aortic diameter. The Tromsø study

Abstract: Ultrasound measurements of the maximal diameter can be obtained with a high degree of accuracy. Inexperienced sonographers may achieve acceptable performance given appropriate training and surveillance.
