Vascular Waveform Analysis of Flap-Feeding Vessels Using Color Doppler Ultrasonography
Figure 2
(a) Patient 1. Waveform of the superior epigastric artery (Type D-4). The was 15.6 cm/sec, the lower limit of the standard value, and RI and PI were 0.34 and 0.50, respectively, apparently lower than the standard values. (b) Patient 1. Waveform of the internal thoracic artery (Type D-2). The waveform was a normal waveform.
