Abstract [en]

Today the primary method in the follow-up after EVAR is computed tomography angiography (CTA) with contrast medium. These patients are followed up annually for the rest of their lives. Contrast-enhanced ultrasound (CEUS) has in recent years been studied as an alternative to reduce the exposure of ionizing radiation and the use of nephrotoxic contrast agents. Our aim with this study was to compare the diagnostic accuracy and to describe the advantages and disadvantages with the survey methods CEUS and CTA at the surveillance after EVAR. According to the aim of the study we formulated one question at issue and 14 scientific articles are including in the literature review. These are examined in relation to scientific quality, evaluated and compiled to a result. The literature review shows that CEUS is an equivalent alternative to CTA in detecting endoleaks and measuring aneurysm sac diameter during follow-up after EVAR. Our conclusion is that CEUS may be an appropriate method of investigation in the follow-up after EVAR to reduce exposure of ionizing radiation and nephrotoxic contrast to the patients.
