目的：探讨骶髂关节彩色多普勒超声检查在早期强直性脊柱炎（ AS）患者诊断中的应用价值。方法56例已确诊的早期AS患者为病例组（112个骶髂关节），同时选择51例健康体检者为健康对照组（102个骶髂关节），分别进行彩色多普勒超声检查，对比分析骶髂关节区域血流信号、分级、血流频谱的分类及分布、血流的显示率、动脉血流阻力指数（ RI ）等。结果病例组骶髂关节区域的血流信号明显多于健康对照组（χ2＝105腚．737， P ＝0．000）；病例组以2～3级为主，健康对照组以0～1级为主；病例组总血流显示率为91．1％，高于健康对照组的35．3％（ P ＜0．01），病例组动、静脉血流显示率分别为80．4％、68．8％，高于健康对照组的32．4％、13．7％（ P均＜0．01）；病例组舒张期正向低阻血流阳性率为74．1％，高于健康对照组1．0％（ P ＜0．01），而高阻血流、反相血流阳性率分别为1．8％、4．5％，低于健康对照组的12．7％、18．6％（ P ＜0．01）；病例组动脉平均RI为（0．56±0．09），低于健康对照组的（0．89±0．10）（ t ＝-12．787， P ＝0．000）。结论 AS患者骶髂关节低阻动脉血流及静脉血流信号都明显增多，彩色多普勒超声有助于其早期诊断。

Objective To investigate the diagnostic value of color Doppler ultrasound examination in sacroiliac joint early ankylosing spondylitis ( AS) .Methods 56 patients who had been diagnosed of early AS patients as case group ( 112 sacroiliac joints), and 51 healthy subjects were enrolled as healthy control group (102 sacroiliac joints, respectively), they were exam by color Doppler ultrasonography , sacroiliac joint, classification, regional blood flow signal classification and distri-bution of blood flow , blood flow display rate , arterial resistance index ( RI) were compared between the two groups .Results Blood flow signal of cases group's sacroiliac joint region were more obvious than the healthy control group (χ2 =105.737, P =0.000);case group mainly with degree of 2 to 3, healthy control group with degree from 0 to 1;the case group total flow rate was 91.1%, higher than that in the healthy control group of 35.3%( P <0.01), case group's artery and venous blood flow display rate were 80.4%and 68.8%, higher than that in healthy control group of 32.4%and 13.7%( P <0.01);the posi-tive rate of diastolic forward low resistance flow in case group was 74.1%, higher than that of the control group with 1.0%(P <0.01), and positive rate of reverse flow and high resistance flow were 1.8%, 4.5%, respectively in the case group, lower than that in healthy control group with 12.7% and 18.6% ( P <0.01); case group's artery mean RI was (0.56 ± 0.09), lower than that of the control group (0.89 ±0.10) ( t =-12.787, P =0.000).Conclusion AS patients with sac-roiliac joint revealed increase of low resistance arterial and venous blood flow signals , color Doppler ultrasonography is helpful in the early diagnosis .
