[Basic research on the mechanism of venous reverse flow in reverse-flow island flap].
OBJECTIVE
To investigate the basic mechanism of venous flow in reverse-flow island flap.


METHODS
Recent relevant literature on the mechanism of venous reverse flow in reverse-flow island flap were extensively reviewed.


RESULTS
The mechanism of venous reverse flow was a multifactorial phenomenon. "Communicating and collateral by pass route" and "incompetent valve route" were two theories.


CONCLUSIONS
The two routes of venous reverse flow in reverse-flow island flap coexist and complement each other.
