[Observation of microcirculation in the free muscular flap during critical ischemic conditions. In vivo experiment].
The influence of 6 hours ischemia on the microcirculation in the rat cremaster muscle isolated on neurovascular pedicle is presented. Microscopic observations of the microcirculation revealed gradual destruction of microvessels beginning in the 4th hour of ischemia. The changes in condensation, structure and colour of the vessels were progressive in time and after 6 hours of ischemia no return of the circulation was possible. Additional 2 hours of observation revealed no reperfusion, so destructive changes after 6 hours proved to be irreversible.
