Figure 1: A. Spectrum of the preoperative IMA demonstrated a systolic
dominance and high RI. B. Measurement of the angle between the initial
segment of IMA and the subclavian artery. C. Color-flow Doppler image of
IMA. D. Postoperative flow spectrum of IMA.
Figure 2. Regression analysis of the correlation between intraoperative
vascular flow and angle between the internal mammary artery (IMA) and
the subclavian artery. Flow: intraoperative flow in the vascular graft;
Angle: angle between the IMA and the subclavian artery.
