- Venous Anastomosis:
- thickest layer in the vein is the adventitia and cannot be stripped away from vessel as it can in the artery & therefore need to use gentle
technique in teasing away the excess adventia and trimming it with scissors;
- vessel walls are not as self supporting as is the artery;
- consequently, in order to avoid suturing the front wall to the back wall, tips of needle and vessel wall should be visualized at all times;
- vessel walls may be kept separated by stream of irrigation fluid;
- frequently more sutures are required in the venous repair than in the arterial repair as a result of greater distensibility
