[Ultrasonic Doppler recording in the diagnosis of the patency of aortocoronary shunts].
Eighty-seven autovenous shunts were examined using ultrasonic dopplerography to assess the patency of aorto-coronary shunts in 32 patients. B-scan was used to visualize the shunts and measure their inner diameter. Liner blood flow rate was measured with a Doppler adapter distinguishing the direction of the flow. Methodologic aspects of the application of this method to the assessment of the patency and function of aorto-coronary shunts are outlined. To verify the method, selective angiography was performed in 18 patients. A significant correlation was demonstrated between the two techniques. Ultrasonic Doppler scanning measuring linear blood flow rate is a safe, non-invasive and reliable method for the assessment of patency of aorto-coronary shunts. It can be used on an out-patient basis.
