Juxtarenal abdominal aneurysms can be misdiagnosed. This study details successful surgical repair in 38 patients, highlighting a novel technique for accurate diagnosis and treatment of these complex aortic aneurysms.

Area of Science:

  • Vascular Surgery
  • Abdominal Aortic Aneurysm Management
  • Medical Imaging in Vascular Disease

Background:

  • Juxtarenal abdominal aneurysms (jAAAs) are defined by their proximity to the renal arteries.
  • Misdiagnosis as suprarenal aneurysms can lead to surgical intervention abandonment.
  • Accurate anatomical assessment is crucial for successful jAAA repair.

Purpose of the Study:

  • To describe the diagnostic challenges and surgical technique for juxtarenal abdominal aneurysms.
  • To report outcomes of a cohort of patients undergoing jAAA repair.
  • To emphasize the importance of specific imaging modalities for jAAA diagnosis.

Main Methods:

  • Retrospective review of 38 patients undergoing juxtarenal aneurysm repair.
  • Analysis of diagnostic imaging including computed tomography, duplex scanning, and selective aortography.

  • Description of surgical technique involving supra-renal aortic cross-clamping and proximal anastomosis at the renal artery level.
  • Lateral position aortography for improved anatomical visualization.

    • Main Results:

    • 18 patients initially misdiagnosed with suprarenal aneurysms.
    • Computed tomography and duplex scanning were often insufficient for accurate diagnosis.
    • Lateral aortography improved visualization of aneurysm extent.
    • Surgical repair achieved a 95% survival rate.
    • Simultaneous reconstruction of associated renal artery disease in three hypertensive patients.

    Conclusions:

    • Juxtarenal abdominal aneurysms present diagnostic challenges due to their location.
    • Aortography in the lateral position is vital for accurate assessment.
    • The described surgical technique allows for successful repair with high survival rates.
    • Management of associated renal artery disease can be integrated into jAAA repair.
