ABSTRACT
The authors fashioned vascularized island flaps using cryopreserved allogeneic vascular bundles as the vascular pedicles in rabbits. Auricular vessels of 8 cm in length were harvested and cryopreserved in liquid nitrogen for 30 days. The allovascular bundles were anastomosed into the recipients' native auricular vessels. Dorsal flaps (6 x 6 cm) in the recipient were raised on the implanted allovascular bundle. Eight days later, the flaps were elevated as vascular island flaps nourished by the allovascular bundle. Computed microangiography demonstrated the anastomoses between the vasculatures of the implanted vessels and the recipient sites 8 days after vascular implantation in the dorsal flap. Flap survival estimation, which was done 1 week after flap elevation, showed flap viability. Allogeneic vascular bundles proved their potential utility as vascular pedicles of autologous tissue transfer.
