Area of Science:

  • Vascular Surgery
  • Radiology
  • Medical Imaging

Background:

  • Abdominal aortic aneurysms (AAAs) are associated with high morbidity and mortality.
  • Accurate diagnosis and preoperative evaluation are critical for successful AAA repair.
  • Ultrasonography is standard for screening, while aortography was historically used for preoperative planning.

Purpose of the Study:

  • To review the evolution of imaging techniques for abdominal aortic aneurysms (AAAs).
  • To highlight the advantages of advanced computed tomography (CT) methods in preoperative evaluation.
  • To discuss the role of imaging in selecting patients for endovascular stent graft repair.

Main Methods:

  • Review of traditional and advanced imaging modalities for AAA diagnosis and preoperative planning.
  • Comparison of ultrasonography, aortography, traditional CT, helical CT, and CT angiography.
  • Discussion of endovascular stent graft repair and imaging requirements.

Main Results:

  • Computed tomography (CT) has largely replaced invasive aortography for preoperative planning.
  • Helical CT and CT angiography provide rapid, detailed 3D imaging of AAAs and adjacent structures.
  • CT angiography precisely guides patient selection for less invasive endovascular stent graft repair.

Conclusions:

  • Helical CT and CT angiography represent a significant advancement in AAA preoperative evaluation.
  • These advanced CT techniques offer superior visualization for endovascular repair planning.
  • Widespread adoption is limited by availability, cost, and lack of standardized protocols.
