“…Parent et al 31 related the Doppler waveform to analysis of type II endoleaks as follows: a 'anterograde and retrograde' pattern was associated with spontaneous resolution, whereas the presence of a monophasic or biphasic waveform was associated with persistent leakage. However, we did not observed this in our study, since two of the three endoleaks correctly identified by ultrasonography, both type IA, were erroneously classified as type II and one was repaired using a endoprosthesis construction and the placement of radiopaque markers is indispensable for correct assessment and interpretation of these X-rays.…”

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.

“…To our knowledge no study has compared the value of CT angiography as an alternative to DU in the follow-up of popliteal artery diseases. However, the majority of reports on DU performance to detect endoleaks after endovascular repair of abdominal aortic aneurysm [26][27][28][29][30][31] found inferior sensitivity and specificity compared to CT angiography. Nevertheless, contrast agents (Levovist) seem to increase the sensitivity of this color-flow DU, but with the risk of more false-positive results [32].…”

Long-term follow-up of surgically excluded popliteal artery aneurysms with multi-slice CT angiography and Doppler ultrasound

et al. 2006

The purpose of this study was to evaluate the role of multi-slice computed tomography (MSCT) angiography in the follow-up of popliteal artery aneurysms (PAAs) that have been operated on. Aneurysm exclusion and progression, graft patency and graft-related complications were analyzed. Fourteen patients with 21 surgically excluded PAAs were evaluated with MSCT angiography with slice thickness of 1.25 mm. The mean follow-up time was 67 months. MSCT demonstrated blood flow in six nonexcluded PAAs (24%), with an average increase in the diameter of 21 mm over time. Fifteen PAAs demonstrated no blood flow and revealed an average decrease of 7 mm in diameter. The origin of this residual perfusion was demonstrated, and collaterals were involved in five of six non-excluded PAAs. In addition, MSCT demonstrated three graft stenoses. Furthermore, two occluded grafts were visualized. Twenty-four percent of the patients after surgical exclusion of PAAs revealed residual perfusion within the aneurysmal sac during follow-up, with a significant increase in the aneurysmal size with MSCT. Moreover, evaluation of the graft patency could also be done as could demonstration of anastomotic abnormalities. Thus, MSCT might be considered as a new tool to evaluate residual collateral feeding of popliteal aneurysmal sac and could be useful in identification and localization of feeding vessels.

“…The presence of multiple type 2 endoleaks and bidirectional SDW may be the strongest predictive factors of increased sac diameter (Beeman et al, 2010). A to-from signal was associated with spontaneous sealing and a mono-biphasic waveform was associated with endoleak persistence (Parent et al, 2002).…”
