An alternative technique of microvascular anastomosis

The femoral arteries and veins of rats were severed and reanastomosed, using either the conventional interrupted suture technique or an alternative interrupted technique that allows the lumen to remain visible throughout the reanastomosis procedure. The alternative technique involves placing the sutures in the posterior wall of the vessel, eliminating the necessity of rotating the microsurgical clamp during the anastomosis. Clinically, this method may be advantageous in cases where the anastomosis is being performed in a deep wound in which there is no room to turn over the microclamp. Additionally, this technique allows the posterior wall of the vessel to be observed throughout the anastomosis procedure, reducing the possibility of accidental placement of sutures through the posterior wall and resulting nonpatency. There was no significant difference between the two techniques in terms of operating time, patency rate, aneurysm formation, arteriography, and histological findings.
