| Abstract: | Objective: This study explored the feasibility of 3D ultrasound (3D US) and 3D contrast enhanced ultrasound (3D CEUS) for evaluation of abdominal aortic aneurysm (AAA) dimensions and endovascular aneurysm repair (EVAR) surveillance. Method: 10 preoperative 3D US and 3D CEUS scans were required of patients with an AAA which were manually segmented. These segmentations were compared to preoperative computed tomographic angiograms (CTA). Volume sizes, diameters, and length measurements were compared between the different imaging modalities. Additionally, 8 3D US scans were made of EVAR patients, which were evaluated visually, to determine their utility for EVAR surveillance. Results: Significant disparities were noted between 3D (CE)US and CTA in measuring AAA dimensions. Therefore, 3D (CE)US is not yet suitable for endograft sizing and EVAR surveillance. However, SonoVue contrast agents proved to be an added value for the assessment of the AAA flow lumen in 3D CEUS scans. Additionally, 3D US was able to determine different EVAR surveillance parameters. Therefore, 3D (CE)US is currently more suitable for EVAR surveillance than for preoperative endograft sizing. Conclusion: While limitations exist, 3D (CE)US shows great potential as imaging modality for the evaluation of AAA and endograft geometry, although further improvements and exploration are certainly needed. |
