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.
Conclusion:
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.
