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

Table 2

Reference values of epigastric artery and subscapular-thoracodorsal artery. The standard values for the superior epigastric artery were: vascular diameter, 0.8 mm or greater; FV, 7 mL/min or faster; 𝑉_max, 15 cm/sec or greater; RI, 0.7 or greater; PI, 2.2 ± 0.8; and AT, ≦100 msec. Those for the deep inferior epigastric artery were: vascular diameter, 1.3 mm or greater; FV, 10 mL/min or faster; 𝑉_max, 25 cm/sec or greater; RI, 0.7 or greater; PI, 2.7 ± 1; and AT, ≦100 msec. Those for the subscapular artery were: vascular diameter, 2 mm or greater; FV, 20 mL/min or faster; 𝑉_max, 30 cm/sec or greater; RI, 0.7 or greater; PI, 4 ± 2; and AT, ≦100 msec. Those for the thoracodorsal artery were: vascular diameter, 1 mm or greater; FV, 5 mL/min or faster; 𝑉_max, 20 cm/sec or greater; RI, 0.7 or greater; PI, 4 ± 2; and AT, ≦100 msec.
