Abstract

Laser Doppler perfusion monitoring was used to assess microcirculatory blood flow, volume, and velocity before and after total arterial or total venous occlusion in 18 buttock island flaps. Critical analysis of these three laser Doppler perfusion values was found to be useful in differentiating adequately perfused skin from inadequately perfused skin, as well as in distinguishing arterial from venous compromise. Multivariable laser Doppler analysis demonstrated that arterial occlusion produced a more rapid and greater percentage decrease in flow and volume values than did venous occlusion. Arterial occlusion produced an insignificant percentage change in velocity values, whereas venous occlusion produced a substantial percentage decrease in velocity values. The substantial intrasubject and intersubject variability in absolute laser Doppler perfusion values suggests that normalized or percentage change values are more revealing than absolute values, although they require the acquisition of reliable baseline data.
