Experience of Vein Grafting in Gottingen Minipigs

摘要

We experimented with vein surgery on Gottingen minipigs. Using the internal jugular vein for the tissue graft, we performed side-to-side anastomosis to the carotid artery, to which it runs parallel. One key point in this surgery was to prevent vasospasm of the carotid artery so as to keep the lumen sufficiently patent during anastomosis. The histopathological findings in the grafts which remained paten resembled those of vein grafts in humans.
