| Summary: | Background/Aim. The delay method is a surgical, pharmacological and combined
method that includes two or more time separated phases, which gives bigger
flap surface. In our research we explored the possibility of flap surface
enlargement in a new arterialised venous flap (AVF) on an experimental
rabbit ear model by the delay surgical method. The aim of this research was
to establish vitality surface of our AVF and to maintain the difference in
flap vital surface between AVF flaps, with or without performing the delay
surgery method. Methods. We used both ears of “Big Chinchilla” rabbits in 10
experimental male animals, divided into two groups, average weight 3-3.5 kg,
and average age 8-10 months. In the first (experimental) group, a venous
flap was arterialised by our method. In the second (control) group, the
venous flap was arterialised 14 days after the delay surgical method. AVF
surface was measured on the 1 and 14 days by the method of trapezoid rule.
Results. Vital surface on our AVF experimental model was bigger than 87% of
elevated flap surface after the delay surgical method. Vital surface on AVF
without delay on our experimental model was bigger than 30% of elevated flap
surface (p < 0.001). Conclusion. Analysis of previous experimental models on
the rabbit ear, non-delayed and delayed (to enlarge flap surface) led us to
conclusion that previously created experimental models of non-delayed AVF
are hemodynamically negative. Our experimental non-delay AVF model is
hemodynamically more positive than previously created models of non-delay
AVF and provides better conditions for AVF survival and enlargement of vital
flap surface of elevated flap. On the other hand, surgical delay method
significantly enlarges vital surface of AFF. |
