Peripheral nerve damage in the lower extremities is a serious problem that often occurs due to trauma, in particular during military operations. Such injuries lead to impaired motor and sensory functions, which significantly affects the quality of life of the injured. The aim of the study was to study changes in hemomicrocirculation in the hind limbs after injury to the sciatic and femoral nerves in the subacute phase. On the third day after injury in group I (transection of both nerves), a significant expansion of arterioles by 87.9% and venules by 77.6% was observed, which indicates an active vascular reaction. On the seventh day in group II (transection of both nerves), the diameters of the vessels decreased, but remained significantly higher than the control values, which indicates the continuation of the recovery processes. In the groups with damage to both nerves, a more pronounced vascular reaction and tissue edema are observed. On the third day, the reaction is most intense, and on the seventh day, stabilization is observed, but the vessels have not yet returned to normal size. This confirms the ongoing processes of restoring blood circulation and tissue structure.
