title: [Basic research on the mechanism of venous reverse flow in reverse-flow island flap].
abstract: 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.
