摘要
目的:探讨应用高频超声对类风湿性关节炎(RA)手指关节病变进行定量分析。方法:选择健康对照组30例,RA病人30例,应用高频超声检测对比观察掌指关节、指间关节滑膜厚度,血流供应、骨及软骨面及软组织情况。结果:RA组共检查出89.0%的掌指关节,82.0%近端指间关节,3.75%远端指间关节滑膜增生,根据增生的滑膜厚度分级为:厚度<2 mm为Ⅰ级,2 mm<厚度<4 mm为Ⅱ级,厚度>4 mm为Ⅲ级;81.6%的掌指关节,73.3%近端指间关节,0.8%远端指间关节血管过度增生,根据其不同程度分级为:无血管为0级,点状血管为Ⅰ级,带状血管为Ⅱ级,多条带状血管为Ⅲ级。病变关节数的20.0%见软骨侵蚀,13.0%见骨侵蚀,58.6%见关节腔积液,20.7%见关节周围软组织肿胀。结论:高频超声能够显示RA病变关节的滑膜炎症、血管翳形成、软骨或骨侵蚀及关节腔积液等病理改变,通过分级诊断为临床诊断、治疗及疗效观察提供详实的影像学资料,是诊断RA病人手部关节病变的首选方法之一。
Objective： To evaluate the imaging of high-frequency uhrasonography（HFUS） in the diagnosis of finger joints damage in rheumatoid arthritis patients. Methods：HFUS exams of the fingers were performed in 30 patients （ 840 finger joints） with clinically diagnosed RA. Results： On HFUS, synovitis of 89.0% articulationes metacarpophalangeae ; 82.0% proximo interphalangeal joints ; 3.75% distal interphalangeal joints were detected, thickness 〈 2mm is I grade ; 2ram 〈 thickness 〈 4ram is Ⅱ grade; thickness 〉 4mm is m grade; and pannus were detected in 81.6% articulationes metacarpophalangeae ; 73.3% proximo interphalangeal joints ; 0.8% distal interphalangeal joints. punctiform blood vessel is I grade;taeniform blood vessel is Ⅱ grade;many taeniform blood vessel is m grade ; Cartilage and bone erosions were found in 20% and 13 % joints, intra-articular fluid was found in58.6%joints,periartieular inflammation tissue was detected in 20.7% joints. Conclusion： Imaging of high fi＇equency ultrasonography can be reliable in the finger joints damage in RA patients. It can orovide a reference for clinically diagnosed RA.
