CRP and blood coagulation disease: The MSK-US group showed lower postoperative levels of Cor, E, NE, IL-6, hs-CRP D-D, and FIB than the conventional group (P&lt; 0.05), suggesting MSK-US's ability to reduce inflammation, alleviate stress reaction, and lower hyperfibrinolysis risk.<h4>Conclusions</h4>MSK-US-guided needle-knife is effective in mitigating perioperative stress response and systemic inflammation in LDH patients while reducing the risk of coagulation disorders and providing a biomarker-driven framework for personalized postoperative management.
