Is contrast-enhanced ultrasound (CEUS) useful for post-EVAR surveillance and characterization of late-onset endoleaks in patients with renal impairment?
Contrast-enhanced ultrasound is a useful imaging modality for post-EVAR surveillance, particularly in patients with renal impairment where standard contrast imaging may be contraindicated.
Answers are grounded in this paper and cite their sources.
CEUS may aid post-EVAR endoleak surveillance in renal impairment; leaves open need for prospective validation.
We report in the case of a patient with an intra-abdominal aortic aneurysm treated with endovascular aneurysm repair (EVAR) who developed renal impairment during the period of follow up. The repair was complicated with an early-onset type II endoleak which later evolved into a late-onset type I endoleak. It was treated with proximal extension of stent graft, with treatment success and follow-up documented on contrast enhanced ultrasound (CEUS). This case illustrates the usefulness of CEUS in post-EVAR surveillance and emphasizes the need for life-long monitoring as late-onset complications are not uncommon.

Gifford et al. (2017) conducted a case report in Intra-abdominal aortic aneurysm (n=1). Contrast enhanced ultrasound (CEUS) was evaluated on Treatment success and follow-up documentation. Contrast enhanced ultrasound (CEUS) successfully documented the evolution and treatment success of a late-onset type I endoleak following endovascular aneurysm repair.
