Abstract: | 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. |
