| Â | Evaluation indicators | Index evaluation method |
|---|---|---|
1 | Operation time | Time from flap preparation to completion of the femoral vein and artery end-to-end anastomosis |
2 | Proper dealing with Microscope | Correct use of microsurgical instruments: 2 points Device usage error: -2 points |
3 | Proper use of needles | Minor deformation of the suture needle: 2 points Large deformation of the suture needle: -2 points |
4 | suture knotting technique | No anastomotic stenosis: 2 points Suture the anterior and posterior walls of the blood vessel: -2 points |
5 | Proper cutting of the thread | The length of the thread is appropriate and uniform: 2 points The length of the remaining thread is inappropriate and uneven: -2 points |
6 | Distance of the suture of vessel’s margins | The needle distance and margin are correct and uniform, and the blood vessel is well valgus: 2 points; Leakage or complete inversion of blood vessels: -2 points |
7 | Proper preparation of blood vessels | The blood vessels and surrounding tissues of the operation segment are entirely separated, and the length of the adventitial stripping around the anastomosis is correct: 2 points The blood vessels and surrounding tissues of the operation segment are not separated, and the adventitia around the anastomosis is not peeled off: -2 points. |
