摘　　要：目的探讨高频超声检查技术对肘管综合征(CUTS)的诊断价值。方法选择31例肘管综合征患者的患侧手臂尺神经作为CUTS组,健侧手臂尺神经作为对照组,应用高频超声成像技术观察尺神经的连续性、内部结构、回声、有无局限性膨大及比邻结构关系,取横断面测量所有患者患侧尺神经与健侧尺神经的横截面积(CSA)。结果尺神经受压明显时神经局段变细,变细处回声明显减低,束状结构欠清晰,卡压近端及远端神经增粗;尺神经卡压瘢痕粘连时,神经增粗回声减低,外膜及束膜回声增强,与周围组织界限模糊;个别患者未见明显卡压段,仅见肘管内尺神经全程肿胀。31例肘管综合征患者患侧肘管尺神经与健侧肘管尺神经比较,患侧尺神经横截面积较健侧明显增大并存在统计学差异(P<0.05)。结论高频超声能动态观察尺神经卡压征象及其周围结构损伤情况,对肘管综合征的诊断有着重要的应用价值。Objective To discuss the value of high-frequency ultrasound in diagnosis of cubital tunnel syndrome （CUTS）. Methods A total of 31 patients suffering from CUTS were enrolled into the research, and all the patients＇ healthy ulnar nerves were also examined as controls. The continuity, internal stnkcture and interior echo of ulnar nerves were observed by high-frequency ultra- sound. We also recorded the limitation of swollen ulnar nerve and its adjacent structure. The cross-sectional area （CSA） of ulnar nerve was also measured. Results When the ulnar nerve was compressed by adjacent structure, it was thinner and it＇ s interior echo was decreased, but the nerve thickening of separate sides was more obvious; when there were scars or adhesions, the nerve became more thickening and it＇ s interior echo was decreased, but the echo of epineurium was increased; for some special cases, we could just find swelling of the ulnar nerve in cubital tunnel without compressed point. The CSA of ulnar nerve in CUTS was obvi- ously larger than that in the controls （ P 〈 0.05 ）. Conclusion High-frequency ultrasound can dynamically evaluate the degree ot ulnar nerve thickening and neural compression in patients with CUTS. The measurement was accurate and feasible.
