摘要
目的:归纳桡神经炎的超声声像图特征,评价超声对桡神经炎的诊断价值。方法:对31例经手术确诊的桡神经炎患者,归纳术前超声声像图特征。以手术所见为金标准,计算超声诊断符合率。结果:桡神经炎的超声声像图分两型。Ⅰ型:神经长段均匀性肿胀,回声减低;Ⅱ型:神经一处或多处缩窄,缩窄两端肿胀、回声减低,呈沙漏样或腊肠样。Ⅰ型病变3例,超声诊断均正确。Ⅱ型病变28例,术中探查共见76处缩窄,超声诊断符合率为92.1%。结论:依据桡神经炎的声像图特征可进行超声诊断,为临床提供及时、准确的形态学信息。
Purpose： To evaluate the diagnostic value of ultrasonography for radial neuritis. Methods： Preoperative ultrasonography was used to examine 31 patients with radial neuritis. The ultrasonographic characteristics were summarized. The diagnostic coincidence was calculated on the basis of intraoperative observations. Results： The ultrasonographic characteristics of radial neuritis were classified into two types. Type I： hypoechoic swelling of the radial nerves. Ultrasonographic diagnoses were all correct. Type II： single or multiple hourglass-like constrictions of the radial nerves. The accuracy was 92.1%. Conclusion： Radial neuritis has distinctive ultrasonographic character. Ultrasonography provides timely and accurate visual information for clinical diagnosis.
