Abstract:
Objective To explore the clinical diagnostic value of high-frequency ultrasound and color Doppler ultrasound in detecting vibration-induced nerve and vascular injuries in patients with occupational hand-arm vibration disease (HAVD). Methods A total of 32 patients with mild occupational HAVD were enrolled as the case group, and 32 healthy volunteers were selected as the control group by the purposive sampling method. High-frequency ultrasound was used to observe the location, morphology, course and echogenic characteristics of the median nerve of the participants in both groups. The cross-sectional area (CSA) of the median nerve at the carpal tunnel inlet was measured. Color Doppler ultrasound was applied to observe the course of the proper palmar digital artery of the index finger, and hemodynamic parameters including peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistive index (RI) were evaluated. Results In the case group, the transverse section of the median nerve among participants appeared flattened, the "honeycomb-like" structure was mildly blurred, epineurial echogenicity was slightly increased, and the margins of hyperechoic fascicles on longitudinal sections were indistinct. The CSA of the median nerve at the pisiform level and the palmar digital RI of the index finger were increased among the participants in the case group compared with the control group (both P<0.01), while PSV and EDV of the proper palmar digital artery of the index finger were decreased (both P<0.01). Conclusion High-frequency ultrasound and color Doppler ultrasound can detect morphological changes in the median nerve and hemodynamic alterations in finger vessels among patients with mild occupational HAVD, objectively reflecting neurovascular injury caused by hand-transmitted vibration and providing scientific and objective imaging evidence for the clinical diagnosis of occupational HAVD.
