The vascular channel of the axial flap and the host bed at the earliest period after restricted (not free) transposition
In order to investigate the vascular channel change of the flap and vascular bond formation dynamics in the zone of flap-recipient (host) bed after transposition we worked out an experimental model with different variants of vascular pedicle flap preparation (intact pedicle flap, periarterial, periv...

| Summary: | In order to investigate the vascular channel change of the flap and vascular bond formation dynamics in the zone of flap-recipient (host) bed after transposition we worked out an experimental model with different variants of vascular pedicle flap preparation (intact pedicle flap, periarterial, perivenous and combined sympathectomy). The vascular channel was investigated with the help of clinical evaluation and investigation of anatomical macro-micro specimen. Clinical-anatomical finding demonstrates abnormal operation of microcirculatory flap channel after all kinds of vascular wall denervation. It was found out that in any variants of flap transposition conduction, the flap lifting and crippling of surrounding tissues causes unavoidable loss of additional (collateral) blood supply sources and disorder of lymph venous outflow. Conduction of pedicle flap sympathectomy in different variants causes additional abnormalities during integration of complicated tissue complex. Preservation of adventitious membrane of arterial vessels creates the most favorable conditions for flap integration and adaptation. |
