Laboratory Animal Model
There are no extensive reports on the typical intraoperative Doppler findings of microvessels in the presence of local or systemic hemodynamic changes, caused, for example, by stenoses or hyperemia, under standardized conditions. Only one report63 deals with the detection and grading of micro-vascular stenoses. Nevertheless there is a need to establish characteristic microvascular Doppler findings, both in normal and impaired flow conditions, in order to evaluate the quality of microsurgical procedures. The findings in large vessels cannot be transferred to small arteries without further investigations.
