End-to-side-anastomosis in the dog using the 3M precise microvascular anastomotic system: a comparative study

Area of Science:

• Veterinary Surgery
• Vascular Surgery
• Biomedical Engineering

Background:

• Vascular anastomosis is a critical surgical procedure.
• Conventional interrupted suturing is time-consuming.
• Novel techniques aim to improve efficiency and outcomes.

Purpose of the Study:

• To compare the 3M precise microvascular anastomotic system with conventional suturing for end-to-side vascular anastomoses.
• To evaluate patency rates, microscopic characteristics, and intraluminal dimensions.
• To assess the time efficiency of the mechanical coupling system.

Main Methods:

• End-to-side anastomoses were performed in canine saphenous arteries and veins.
• The 3M precise microvascular anastomotic system was compared to interrupted suturing.
• Patency, microscopic features, and intraluminal dimensions were analyzed.

Main Results:

• Both techniques yielded similar patency rates and microscopic characteristics.
• The mechanical coupling system significantly reduced anastomosis time compared to suturing.
• No significant differences in intraluminal dimensions were observed.

Conclusions:

• The 3M precise microvascular anastomotic system is a time-efficient alternative for vascular anastomosis.
• The system achieves comparable patency and microscopic results to conventional suturing.
• This technology offers potential benefits for surgical efficiency in vascular repairs.
