Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Radiology

Background:

  • Aortic aneurysm evaluation lacks a standardized protocol.
  • Clinical decisions are influenced by case specifics, resource availability, and surgeon preference.

Purpose of the Study:

  • To outline the optimal use of various imaging modalities in aortic aneurysm assessment.
  • To highlight the strengths of each technique in different clinical scenarios.

Main Methods:

  • Review of current literature and clinical practice guidelines for aortic aneurysm imaging.
  • Comparative analysis of sonography, CT, angiography, and MR imaging.

Main Results:

  • Sonography is ideal for screening and monitoring uncomplicated aortic aneurysms.

  • CT excels in preoperative/postoperative evaluation and complication assessment.
  • Angiography aids in defining vascular anatomy and visceral involvement, though its routine preoperative use is debated.
  • MR imaging provides advanced visualization and staging capabilities.

    • Conclusions:

    • The choice of imaging modality for aortic aneurysms should be individualized.
    • A multimodal imaging approach often provides comprehensive evaluation.
    • Each imaging technique plays a crucial role in the management of aortic aneurysms.
