痛风性关节炎的高频超声表现

The high-frequency Ultrasonography of diseased joints in Gouty arthritis

目的:了解痛风性关节炎病变关节的高频超声表现。方法:痛风性关节炎患者85例,利用高频超声检查病变关节,观察二维声像图及彩色多普勒血流显像情况。结果:痛风性关节炎病变关节的高频超声表现主要为:(急性期)滑膜炎大部分可见明显血流信号;尿酸盐结晶;关节腔积液。(慢性期)关节软骨及骨质的的破坏;痛风石的出现。结论:超声检查可以观察到痛风性关节炎患者病变关节的病理改变,具有明确的声像图表现,在判断病情活动性和随访中有较高的应用价值。

Objective To study the high-frequency ultrasound appearance of diseased joints in gouty arthritis.Methods The diseased joints of 85 gouty arthritis patients were examined by the high-frequency ultrasound.The 2-demensional and color Doppler flow images were evaluated.Results The ultrasound appearance of diseased joints in gouty arthritis were：（acute phase） synovitis （color flow sign much joints）joint effusion;MSU.（chronic phase）bone erosion and the stone of MSU.Conclusion Abnormalities of diseased joints in gouty arthritis could be identified by ultrasonography.Ultrasonography is useful in diagnosis and follow-up diagnosis in gouty arthritis.
