title: [Vascular anatomy and clinical applications of the distally based superficial sural artery island flap].
abstract: OBJECTIVE
  To document the vascular anatomy of the distally based superficial sural artery flap and to study the vascular anastomoses between the superficial sural artery and the septocutaneous perforators of the peroneal artery.
  
  
  METHODS
  Ten fresh human cadavers were injected with lead oxide, gelatin and water. Twenty lags were then dissected and an overall map of the cutaneous vasculature was constructed. Vascular communications between the superficial sural artery and the lowest septocutaneous perforator of the peroneal artery was evaluated to determine the cutaneous vascular territory of the superficial sural flap. The distally based superficial sural artery island flap was used in 26 cases.
  
  
  RESULTS
  There is constant vascular anastomosis between the superficial sural artery and the lowest septocutaneous perforator of the peroneal artery. The 26 flaps survived uneventfully except for two of partial fat necrosis.
  
  
  CONCLUSIONS
  The anatomic information enhances our understanding of flap design.
