摘要：

Intraoperative Doppler-derived measurements of blood flow velocity were used to characterize the hemodynamics in 6 internal mammary artery grafts before and after anastomosis to the left anterior descending artery. Pulsed Doppler spectrum analysis demonstrated a change from a systolic to a predominantly diastolic flow pattern. The presented technique is a valuable aid to differentiate intraoperatively between normal and low flow states in the internal mammary artery. In addition, this study serves as a pilot study to investigate the clinical applicability of Doppler spectrum analysis in the functional assessment of the internal mammary artery in the pre- and postoperative stages of myocardial revascularization.
