Anastomosis patency is presented as number of each group; other data are presented as mean and standard deviation. A: sham group, B: end-to-end anastomosis group, C: end-to-end anastomosis + ligation of the contralateral EJV group, D: end-to-side anastomosis group, E: end-to-side anastomosis + ligation of the contralateral EJV group. BP: Blood pressure. *indicates a significant change compared to group A, †indicates a significant change compared to group B and group C. aindicates a significant change compared to baseline level of venous BP.
In each group of ten rabbits six animals were used for ink perfusion and four were used for DSA examination/.
