RESUMEN

@#Objective　To investigate the changes and correlation of ultrasound measurements of sural nerve and Achilles tendon in patients with type 2 diabetic peripheral neuropathy.Methods　High-frequency ultrasound was used to analyze the internal structure and surrounding tissues of the sural nerve and Achilles tendon in 42 patients with type 2 diabetes mellitus with DPN,42 patients with T2DM without DPN and 42 non-diabetic healthy adults.The cross-sectional area of the sural nerve and the thickness of the Achilles tendon near the end.The cross-sectional area of the sural nerve and the thickness of the achilles tendon near the end were compared between the groups,and Pearson correlation analysis and scatter statistics was performed.Results　The abnormal sonogram of the DPN group was significantly higher than that of the NDPN group.The number of abnormal sonograms detected in the DPN group was 36 cases,accounting for 83.33%.The abnormal sonograms detected in the non-DPN group were 14 cases,accounting for 33.33 %.The cross-sectional area of the sural nerve and the thickness of the Achilles tendon in the DPN group were larger than those in the NDPN group and the non-diabetic group,and the difference was statistically significant (P<0.05).The cross-sectional area of the sural nerve was positively correlated with the thickness of the Achilles tendon in patients with DPN (r=0.747,P<0.05).Conclusion　The incidence of sural nerve and Achilles tendon lesions is high in patients with diabetic peripheral neuropathy.High-frequency ultrasound can help to detect the sural nerve and Achilles tendon lesions in patients with DPN.They are of great value in the collaborative assessment of DPN lesions.
