Patient Selection Criteria for Endovascular Aortic Aneurysm Repair: Optimizing Outcomes

Area of Science:

• Vascular Surgery
• Medical Imaging
• Biomedical Engineering

Background:

• Endovascular aortic aneurysm repair (EVAR) is a minimally invasive alternative to open surgery for abdominal aortic aneurysms.
• Successful EVAR outcomes are highly dependent on appropriate patient selection.

Purpose of the Study:

• To review the critical patient selection criteria for EVAR.
• To highlight the importance of anatomical assessment and device suitability for procedural success.

Main Methods:

• Review of current literature and guidelines on EVAR patient selection.
• Analysis of key anatomical factors: aneurysm size, morphology, proximal and distal neck quality.
• Examination of imaging assessment techniques and device-specific variables.

Main Results:

• Aneurysm size, morphology, and neck characteristics significantly impact EVAR suitability.
• Accurate imaging and anatomical assessment are crucial for device selection and procedural planning.
• Patient selection directly influences technical success and complication rates like endoleaks and migration.

Conclusions:

• Meticulous patient selection is paramount for maximizing EVAR success and minimizing complications.
• Understanding EVAR eligibility criteria is essential for expanding its application to a wider patient population.
• Ongoing technological advancements in EVAR require continuous refinement of patient selection protocols.
