Only few data are known concerning haemodynamic parameters and pathomechanisms of small vessels and bypass grafts. No easy-to-use bedside method exists for monitoring. We developed a miniaturised implantable Doppler probe linked to a 20 MHz pulsed Doppler system. In a circulation model and in animal studies we can show the accuracy of this method. We conclude that the implantable pulsed Doppler system is a sensitive method for monitoring the haemodynamics of small vessels.
关于小血管和旁路移植物的血流动力学参数及病理机制，已知的数据很少。目前尚无易于使用的床边监测方法。我们开发了一种与20MHz脉冲多普勒系统相连的小型化植入式多普勒探头。在循环模型和动物研究中，我们能够证明该方法的准确性。我们得出结论，植入式脉冲多普勒系统是监测小血管血流动力学的一种灵敏方法。
