Abstract

INTRODUCTION

The aim of this study was to determine the value of Doppler sonography for evaluation of ulnar neuropathy at the elbow (UNE).

METHODS

A total of 102 patients with a clinical suspicion of UNE and 50 healthy controls were examined by Doppler and gray-scale sonography.

RESULTS

Intraneural vascularization was found in 31 (46.3%) of 67 patients with confirmed UNE and in 3 (6.0%) of 50 healthy controls. Combining gray-scale sonography measurement of nerve size and the presence of intraneural vascularization increased sensitivity by 3%, but decreased the specificity. Patients with intraneural vascularization had more severe disease than those without intraneural vascularization (P < 0.05). The variables obtained by Doppler sonography were associated with the severity of UNE (P < 0.05).

CONCLUSIONS

Doppler sonography is not helpful for diagnosing UNE but can be used to assess the severity of UNE. Muscle Nerve 54: 258-263, 2016.

摘要

引言

本研究旨在确定多普勒超声在评估肘部尺神经病变（UNE）中的价值。

方法

对102例临床怀疑患有UNE的患者和50例健康对照者进行了多普勒和灰阶超声检查。

结果

在67例确诊为UNE的患者中，31例（46.3%）发现神经内血管形成，在50例健康对照者中，3例（6.0%）发现神经内血管形成。将灰阶超声测量的神经大小与神经内血管形成情况相结合，敏感性提高了3%，但特异性降低。有神经内血管形成的患者比没有神经内血管形成的患者病情更严重（P<0.05）。多普勒超声获得的变量与UNE的严重程度相关（P<0.05）。
