Table 1 Flow measurements timeline

From: A randomized comparison of flow characteristics of semiskeletonized and pedicled internal thoracic artery preparations in coronary artery bypass

No. Time point Flow type Measurement Site on ITA
F1 Beginning of harvest (native ITA flow) Pulsatile flowa TTF Middle third
F2 End of harvest Pulsatile flowa TTF Middle third
F3 End of harvest Pulsatile flowa Free flow Distal end
F4 Before grafting Non-pulsatile flowb Free flow Distal end
F5 End of procedure (post-CPB) Pulsatile flowa TTF Middle third
  1. aPulsatile flow is patient pulsatile flow, measured at systolic blood pressure of 110–130 mmHg and diastolic blood pressure of 60–80 mmHg
  2. bNon-pulsatile flow is pump non-pulsatile flow, measured during cardiopulmonary bypass at maintained mean arterial pressure of 70 mmHg and pump flow of 3.0-3.5 L/min/m2
