title: [Microcirculation of lateral groin skin flaps: monitoring and clinical application].
abstract: OBJECTIVE
  To monitor the microcirculation of lateral groin skin flaps.
  
  
  METHODS
  The microcirculation in 12 lateral groin skin flaps was monitored continuously by laser doppler flowmetry (LDF).
  
  
  RESULTS
  The microcirculatory changes in lateral groin skin flaps were divided into two phases: rapid rising (2-6 days after operation) and plateau (6-11 days after operation). PU values were 2.83 +/- 0.46, 3.21 +/- 0.41, 3.66 +/- 0.43, 4.77 +/- 0.71, 7.08 +/- 0.37; 7.53 +/- 0.41, 7.57 +/- 0.62, 7.70 +/- 0.44, 7.60 +/- 0.26, 7.58 +/- 0.17.
  
  
  CONCLUSIONS
  In clinical application, division of the lateral groin skin flaps within the plateau, and the values (PU) returned to or exceeded 50% of that values (PU) determined before application of the tourniquet, causes flaps survival (100%). The time of division was decreased to 8-11 postoperative days in our clinical application.
