By infusing the femoral artery in a fresh chicken leg with dyed water after forming a microvascular anastomosis in that artery, we can detect failures of false sutures due to dyed-water leakage, vascular distortion and the formation of pits on the blood vessel wall. Using a chicken leg, a surgical trainee can also practice microvascular anastomosis at multiple positions on the artery within a short time. Therefore, this model is useful for a novice trainee to practice microvascular surgical techniques.
