Area of Science:

  • Biomedical Engineering
  • Surgical Technology
  • Vascular Surgery

Background:

  • Vascular graft anastomosis is crucial for surgical success.
  • Traditional suturing methods can lead to complications.
  • Exploring alternative joining techniques like laser welding is essential.

Purpose of the Study:

  • To evaluate the feasibility and effectiveness of laser welding for attaching biologic vascular grafts.
  • To assess the integrity and healing of laser-welded anastomoses in peripheral and coronary arteries.

Main Methods:

  • Utilized a Nd-YAG laser with a contact method for anastomosis.
  • Welded heparinized canine carotid artery grafts to canine peripheral and coronary arteries.
  • Assessed weld success, patency, anastomotic strength, and histological healing over time.

Main Results:

  • Achieved a 92% success rate in peripheral artery and 83% in coronary artery procedures.
  • Demonstrated a 100% early patency rate with anastomotic sites withstanding >300 mmHg.
  • Histology showed minimal damage, smooth surfaces, low inflammation, and strong fusion by 1 week post-op.

Conclusions:

  • Nd-YAG laser welding is a viable and effective method for anastomosing biologic vascular grafts to peripheral and coronary arteries.
  • The technique provides strong, well-healing anastomoses with high patency rates.
  • Laser welding offers a promising alternative to traditional suturing in vascular reconstruction.
