Abstract：Objective To evaluate the morphological changes of the small nerves in lower extremity with high-resolution ultrasonography in type 2 diabetes mellitus (T2DM). Methods 84 cases of T2DM patients were divided into four different groups according to TCSS score [group Ⅰ (0-5 point), group Ⅱ (6-8 point), groupⅢ (9-11 point), group Ⅳ (12-19 point)]. The ultrasonic feature of posterior tibial nerve, sural nerve and saphenous nerve were observed to observe the relationship between ultrasound findings and scoring. Results Abnormality rate admitted from ultrasound findings are as follows. In group Ⅳ, nerve abnormality rate was the highest, followed by group Ⅲ, group Ⅱ and group Ⅰ (P < 0.05). The major manifestations are obscure border between spineurium and peripheral tissue , nerve bundle mesh like structure disappearing , enlargement of posterior tibial nerve and sural nerve. There was no statistical difference in irregular abnormality rate (P > 0.05). The saphenous nerve epineurium abnormality increased in group Ⅱ and Ⅲ compared with group Ⅰ and Ⅳ(P <0.05). Abnormality rate of 3 neural ultrasound decreased in line with sural nerve, posterior tibial nerve and saphenous nerve. Conclusions Certain correlation was observed between TCSS and never ultrasonic feature in T2DM patients. The higher TCSS scores is, the greater chance of presence of abnormal sonographic features of nerves will be. The sural nerve abnormality was higher than others.
