A new microvascular anastomosis technique using muscle graft

Area of Science:

• Vascular Surgery
• Biomedical Engineering
• Surgical Innovation

Background:

• Microvascular anastomosis is crucial in reconstructive surgery.
• Standard techniques can be time-consuming and require significant suture material.
• Improving efficiency and outcomes in microvascular repair remains an ongoing goal.

Purpose of the Study:

• To introduce and evaluate a novel microvascular anastomosis technique.
• To compare the efficacy of autogenous muscle and fascial grafts in microvascular repair.
• To assess the impact of the new technique on procedure time, suture usage, patency, aneurysm formation, and anastomotic leakage.

Main Methods:

• Forty-five male Sprague-Dawley rats underwent femoral artery anastomosis.
• Three groups were established: standard repair, muscle graft wrap, and fascial surface graft wrap.
• Procedure time, suture count, patency, aneurysm formation, and leakage were analyzed.

Main Results:

• Both muscle graft and fascial surface techniques significantly reduced time and suture usage compared to controls (p < 0.05).
• No significant differences in patency rates or aneurysm formation were observed among the groups (p > 0.05).
• Grade 2 anastomotic leakage was less frequent in the graft groups versus the control group (p < 0.05).

Conclusions:

• The novel microvascular anastomosis technique using muscle or fascial grafts is more efficient than standard repair.
• This technique offers comparable patency and aneurysm rates with reduced leakage.
• The fascial surface graft approach presents a promising alternative for microvascular anastomosis.
