Comparison of endoleak diagnostic efficacy of contrast-enhanced ultrasound and computed tomography angiography after endovascular aneurysm repair for abdominal aortic aneurysm

and misdiagnosed by CTA, while one patient had Type 3 endoleak and three patients had Type 2 endoleak also misdiagnosed by CTA.CEUS achieved 97.14% sensitivity, 100% specificity, 100% PPV, 85.71% NPV, and 0.9857 AUC, outperforming CTA (78.57% sensitivity, 46.15% specificity, 75.86%PPV, 50% NPV, 0.6621 AUC) (p = 0.0033).Mean AAA sac diameter measurements between CEUS and CTA were comparable (p = 0.277). Conclusions:CEUS imaging outperformed CTA for endograft visualization and endoleak diagnosis, in line with similar European studies.Real-time temporal visualization of endoleaks and elimination of iodinated contrast with CEUS exams give endovascular surgeons a beneficial complement to CTA to detect endograft endoleaks and optimize endovascular treatments during long-term follow-up of post-EVAR AAA patients.
