[Microcirculation of thoraco-acromial flaps: monitoring and clinical application]
1Plastic Surgery Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences, Beijing 100041, China.
Objective:
To monitor the microcirculation of thoraco-acromial flaps.
Methods:
The microcirculation in 12 thoraco-acromial flaps was monitored continuously by laser Doppler flowmetry (LDF).
Results:
The microcirculatory changes in thoraco-acromial flaps were divided into two phases: rapid rising (2 - 4 days after operation) and plateaurising (4 - 7 days after operation). PU values were 7.4 +/- 2.0, 7.6 +/- 2.3 and 7.3 +/- 1.6.
Conclusions:
In division of the thoraco-acromial flaps within the plateau, the value (PU) returned to or exceeded 50% of that before application of the tourniquet. All flaps survived. The time of division was decreased to 6 - 8 after operation days.
