Vascular Waveform Analysis of Flap-Feeding Vessels Using Color Doppler Ultrasonography

Figure 5

Baba’s classification of the vascular waveform. Baba classified vascular waveforms into 3 types: type A: systolic waves rise steeply and are followed by reflux components in diastole, type B: the waveform is comprised of only systolic waves and diastolic waves are lost, and type C: systolic waves rise slowly and continue antegradely in diastole.
