目的探讨超声在类风湿关节炎(RA)诊断及病程观察中的运用价值。方法选择临床已经确诊的23例RA患者进行超声检查,观察病变关节的滑膜厚度、关节腔积液程度、软骨及骨质破坏及彩色多普勒血流变化等情况。结果 RA患者病变关节可见超声表现有滑膜增厚、血管翳形成、关节腔积液以及受累腱鞘的改变,病变较重者可见软骨及骨质的侵蚀破坏。结论超声能早期反映类风湿性关节炎关节病变,尤其对于早期滑膜及软骨的病变更优于传统X线检查,动态观察可有效评估其疗效。超声检查对RA的诊断及其疗效评价有独特运用价值。
Objective To investigate the value of ultrasound in the diagnosis and course of rheumatoid arthritis (RA). Methods Twenty-three patients with RA confirmed clinically underwent ultrasonography. The synovial thickness, joint effusion, cartilage and bone destruction and color Doppler flow changes were observed. Results The pathological changes of RA patients showed synovial thickening, angiogenesis, joint effusion, and tendon sheath involvement in the diseased joints. Erosion damage of cartilage and bone could be observed in severe cases. Conclusion Ultrasound can early reflect the rheumatoid arthritis joint disease, especially for the early synovial and cartilage lesions better than the traditional X-ray examination, dynamic observation can effectively evaluate the efficacy. Ultrasound diagnosis of RA and its efficacy evaluation has a unique value.
