[An experimental study of transplantation of prefabricated axial flap with an vascular bundle]

To study the prognostic results of different prefabricated axial flaps with different operative methods.

Eighteen New Zealand rabbits and two operative patterns were utilized in this study. In group A, the vascular bundles of the left ear were transferred through tube flaps to the left neck. In group B, the central artery and veins of the right ear were transposed through skin tunnel to the right neck. After 4 weeks of operation, transplantation and vessel perfusion were made.

Group A: The flaps of 10 cases were 100% survival, while there were 2 cases with 85% survival, and 2 flaps with necrosis. Group B: The flaps of 8 cases were 100% survival, while there were 5 sides with 50%-85% survival and 1 necrotic flap. The vessel perfusion demonstrated that there was no difference between the density values of the direct sprouting vessels from the transplanted vascular pedicles. There was no statistical difference between the two groups in flap survival and vessel perfusion.

There is no obvious difference between the above two methods of prefabricated axial flap.
