[Dopplerography and ultrasonic scanning of the internal thoracic artery and of mammary-coronary shunts].
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.
