Area of Science:

  • Vascular Surgery
  • Medical Robotics
  • Endovascular Interventions

Background:

  • Conventional endovascular surgery for aortic aneurysms has limitations despite being superior to open surgery.
  • Robotic endovascular systems are being developed as an alternative to overcome these limitations.

Purpose of the Study:

  • To compare the efficacy and outcomes of conventional endovascular procedures versus the robotic endovascular approach in aortic aneurysm repair.

Main Methods:

  • Systematic review and comparison of studies evaluating robotic versus conventional endovascular aortic aneurysm repair.
  • Analysis of procedure times, fluoroscopic exposure, surgical movements, and performance scores.

Main Results:

  • Robotic procedures demonstrated reduced procedure time (up to 6 times faster) and fluoroscopic exposure time (by 12 minutes).
  • In-vitro studies showed a significant reduction in required movements (up to 10 times) with robotic surgery.
  • Robotic endovascular approach showed improved catheter stability, shorter learning curve, and better performance in cannulating tortuous vessels.

Conclusions:

  • Robotic endovascular technology offers multiple advantages over conventional methods for aortic aneurysm repair.
  • Limitations include system cost, catheter size, and preoperative setup time.
  • Further comparative studies on cost-effectiveness, safety, and complex cases are essential for widespread adoption.
