04.10 Rat Abdominal Aorta Model Anastomotic concept and anastomosis - 180 degrees, 12 stitches, caliber difference 1

Advanced/optional: anastomotic concept and anastomosis – 180 degrees,12 stitches, caliber difference

Anastomosing vessels with a small difference in diameter can be learned when dilating only one vessel stump of the abdominal aorta during the preparation of the vessel ends.
The 180-degree concept has the advantage of simplifying the appreciation of relative distances between stitches in two different sized vessels.
Except for the difference in vessel diameter, the 180-degree concept is performed as presented in the chicken leg model.

 

Final suggestions

If your anastomosis is patent, cover it up with moist gauze and leave it alone for 20 minutes. Then test its patency once more.
If you have handled the abdominal aorta gently and assume damage to the intimal layer to be minimal you can perform further anastomoses on it for as often as you can approximate the vessel ends.
If the anastomosis is patent you can also work on the femoral vessels or inferior vena cava. If it is not patent you can work on the neck vessels.
