The study was performed in 22 patients with ischemic heart disease who underwent direct myocardial revascularization. The functional and structural state of mammary arteries was estimated by the noninvasive Duplex scanning before surgical operation to evaluate the possibility of using them as mammary-coronary bypasses (MCB). Direct blood velocity measurements in the bypasses during aortocoronary bypass (ACB) surgery and MCB were made by ultrasound pulsed Doppler system with a 10 MHz transducer. A method was developed for noninvasive Duplex scanning and evaluation of coronary bypass flow in the postoperative period by using the ultrasound system with 5 a MHz phased array linear transducer, which enabled one to obtain the bypass image in B-mode and the Doppler velocity spectrum inside the bypass.
该研究对22例接受直接心肌血运重建的缺血性心脏病患者进行。在手术前通过无创双功扫描评估乳内动脉的功能和结构状态，以评估将其用作乳内动脉-冠状动脉旁路移植术（MCB）的可能性。在主动脉冠状动脉旁路移植术（ACB）手术和MCB过程中，使用带有10 MHz换能器的超声脉冲多普勒系统对旁路中的直接血流速度进行测量。开发了一种用于术后无创双功扫描和评估冠状动脉旁路血流的方法，该方法使用带有5 a MHz相控阵线性换能器的超声系统，能够在B模式下获得旁路图像以及旁路内的多普勒速度频谱。
