Endovascular aortic aneurysm repair (EVAR) is increasingly used, but challenging patient anatomy and renal concerns can limit its feasibility. This review discusses technical strategies for overcoming these EVAR limitations.

Area of Science:

  • Vascular Surgery
  • Minimally Invasive Procedures
  • Medical Device Technology

Background:

  • Endovascular aortic aneurysm repair (EVAR) is gaining popularity due to favorable clinical outcomes and patient preference for minimally invasive surgery.
  • The application of EVAR is expanding to younger, healthier patient populations.
  • Anatomical variations and technical challenges can restrict EVAR feasibility.

Purpose of the Study:

  • To discuss technical maneuvers and considerations for performing EVAR in patients with challenging anatomy.
  • To address concerns regarding renal function in patients undergoing EVAR.
  • To highlight strategies for overcoming limitations in EVAR procedures.

Main Methods:

  • Review of technical strategies for managing difficult access, short/tortuous/calcified landing zones, and complex iliac aneurysms.

  • Discussion of contrast load implications for renal function in EVAR patients.
  • Consideration of surgical techniques for challenging EVAR cases.

    • Main Results:

    • Specific anatomical challenges include difficult access, unfavorable landing zones, and concurrent iliac aneurysms.
    • Renal failure is a concern due to contrast media requirements for EVAR and follow-up.
    • Technical maneuvers can help overcome anatomical limitations in EVAR.

    Conclusions:

    • EVAR is a valuable treatment, but anatomical factors and renal status require careful consideration.
    • Technical expertise is crucial for successful EVAR in complex cases.
    • Strategies exist to mitigate risks and improve EVAR outcomes in challenging patients.
