“…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]. However, CT angiography carries some disadvantages, such as increased radiation exposure, potential contrast allergy and worsening of renal insufficiency.…”

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.

“…Generally, it is considered to be more accurate than ultrasound without contrast, and similar to magnetic resonance imaging (MR) and CT (Cantisani et al, 2011;Iezzi et al, 2009;Mirza et al, 2010;Sun 2006). McWilliams et al (2002) investigated 53 patients and found contrast enhanced ultrasound to be more sensitive than unenhanced ultrasound in detection of endoleak when compared to CT, but concluded that ultrasound (with or without contrast) was less reliable than CT. On the contrary, several other authors have concluded that contrast enhanced ultrasound may perform better than CT in detection of endoleak (Carrafiello et al, 2006;Clevert et al, 2008;Henao et al, 2006;Ten Bosch et al, 2010). Bakken & Illig (2010) presented a review summarizing use of ultrasound for detection of endoleak.…”

“…Sonographic contrast agents enhance the capability of color duplex imaging to detect endoleaks (McWilliams et al, 2002;Napoli et al, 2004). Are typically microbubbles of a perfluorocarbon gas encapsulated within a thin lipid or human albumin shell for stability while circulating in the blood pool.…”

Detection of Endoleak with Enhanced Ultrasound Imaging: Comparison with Biphasic Computed Tomography

Abstract: Ultrasound scanning with or without contrast enhancement was not as reliable as CT in diagnosing type II endoleak. CT imaging remains our surveillance modality of choice.
