Chinese Journal of Medical Imaging 2014;(10):781-783,785
Purpose To explore the ultrasonic features of tibial nerve (TN) in tarsal tunnel of type 2 diabetes mellitus patients with diabetic peripheral neuropathy (DPN), and to provide the basis for assessment and treatment. Materials and Methods Fifty-four patients with type 2 diabetes mellitus were divided into the DPN group including 31 patients with diabetic periphreal neuropathy and the non-DPN group including 23 patients without diabetic periphreal neuropathy, 22 cases of non diabetic patients were also enrolled as the control group, all the subjects underwent medial tibial nerve ultrasound examination, and the ultrasonic features of tibial nerve (including morphological parameters:left-right diameter, anterior-posterior diameter, thickness sectional area and color Doppler lfow signals) were compared. Results Left-right diameter and anterior-posterior diameter of DPN group were larger than those of non-DPN group and the control group (P<0.01). Ultrasonic features of tibial nerve of DPN group included nerve bundle hypoechoic, vaguedscreen clothstructure, thickening and fuzzy of neural membrane, and the unclear boundaries to adjacent tissue. There was no statistically signiifcant difference in color Doppler signal of TN (P>0.05) among the DPN group, non-DPN group and the control group. Conclusion There are some characteristics features of tibial nerve in tarsal tunnel of type 2 diabetes mellitus patients with DPN, ultrasound can be used to evaluate the morphology of TN in type 2 diabetes mellitus patients with DPN and to provide morphological basis for evaluation and treatment selection.
