Fig 1.
Flap perfusion analyzed with the “Autoview” function.
Fig 1A: the bright zone on the left is the flap zone where fluorescence is the higher and on which perfusion parameters are estimated. The red curve is the curve of fluorescence across the time. Fig 1B: Definition of the four regions of interest (ROI). Yellow-colored zones are used to calculate perfusion parameters.

Fig 2A: Perfusion pattern type «1». Fig 2B: Perfusion pattern type «2». Fig 2C: Perfusion pattern type «3». Dynamic color analysis representing fluorescence of the flap over time. Red zone is the best perfused one and blue one, the less perfused one.
Fig 3.
Flap zones and quantitative perfusion parameters.
This boxplot figure represents distributions of ingress (above) and ingress rate (below) calculated on the four flap zones as defined above. When quantitatively assessed, perfusion is the higher in ROI 2 (zone I) and the lower in ROI 4 (zone IV).

Flap perfusion pattern and main perforator location.
Circled symbol represents the mean location of perforator emergence for each perfusion pattern (as defined above).
