Hence, we speculated that the abundant muscle blood perfusion in the Micro-T + PRP group may be attributed to the fact that the regenerated nerves reinnervate the activity of targeted muscle, upregulate VEGF expression, stimulate angiogenesis, and improve vascular permeability, suggesting that CEUS examination of the target muscle can also provide useful information for the prognosis of peripheral nerve injury. The gene discussed is VEGFA; the disease is peripheral nerve injury.
