This study developed a piglet model for laparoscopic treatment of abdominal aortic aneurysms (AAA). The model successfully simulated challenges, demonstrating feasibility for future research in minimally invasive AAA repair.

Area of Science:

  • Minimally Invasive Surgery
  • Vascular Surgery
  • Surgical Innovation

Background:

  • Laparoscopic approaches to abdominal aortic aneurysm (AAA) may enhance patient recovery.
  • Developing a reliable animal model is crucial for studying laparoscopic AAA treatment challenges.

Purpose of the Study:

  • To create an animal model simulating difficulties in laparoscopic treatment of abdominal aortic aneurysms (AAA).

Main Methods:

  • An AAA model was created in twelve piglets by suturing Dacron to an aortotomy.
  • Piglets underwent laparoscopic AAA repair 4-15 days after model creation.

Main Results:

  • All laparoscopic abdominal aortic aneurysm (AAA) procedures were successful.
  • Average procedure time was 210 minutes, with aortic cross-clamping at 55 minutes.

  • Minor complications included splenic trauma, anastomotic stenosis, and lumbar vein bleeding.

    • Conclusions:

    • Laparoscopic abdominal aortic aneurysm (AAA) resection is achievable in this novel animal model.
    • The piglet model effectively replicates challenges seen in human laparoscopic AAA repair.
