     【摘要】目的探讨原发性干燥综合征的泪腺超声特征。方法病例组选取我院风湿科确诊为原发性干燥综合征的女性患者53例，对照组为健康成年女性61例，两组行超声检查，观察两组泪腺的大小、形态、内部回声，彩色多普勒血流显像(CDFI)检测泪腺动脉的血流形态，频谱多普勒检测泪腺动脉的收缩期峰值流速(PSV)和阻力指数(RI)。结果病例组中超声探及双侧泪腺肿大29例(54.7%),内部回声不均匀,可见大量囊性改变,CDFI显示泪腺动脉的血流形态呈长条状，频谱多普勒检测PSV和RI较对照组均明显增高(P<0.01);探及单侧泪腺肿大13例(24.5%),内部回声不均匀,有少量囊性改变,CDFI显示泪腺动脉的血流形态呈短棒状，频谱多普勒检测PSV和RI较对照组均明显增高(P<0.01);探及无泪腺肿大11例(20.8%),内部回声较均匀,无囊性改变,CDFI显示泪腺动脉的血流形态呈点状，频谱多普勒检测PSV和RI较对照组差异无显著性(P>0.05)。病例组中两两比较差异有非常显著性(P<0.01)。结论超声可作为原发性干燥综合征泪腺病变的重要诊断方法。

    【Abstract】 Objective To explore the role of ultrasonography in the evaluation of the lacrimal glands in primary Sjogrens syndrome.Methods 53 female patients suffered from primary Sjogrens syndrome and 61 normal women were examined by ultrasonography.Results 29 cases were bilaterally larger in lacrimal glands than control subjects(P<0.01) with peak systolic velocity (PSV) and resistance index (RI) of the lacrimal arteries higher than normal(P<0.01);13(24.5%) cases were unilatera larger than control subjects(P<0.01).In color Doppler flow imaging (CDFI) PSV and RI of the lacrimal arteries were higher than normal(P<0.01).About 11 cases had no difference from the normal(P>0.05).Conclusion Ultrasonography is an important method for the diagnosis of lacrimal gland disordors in primary Sjogrens syndrome. ......
