超声评价Perthes病髋关节血流

目的 探讨Perthes病髋关节血流的彩色多普勒成像特征.方法 Perthes病患儿45例,均为单侧股骨头坏死,健侧为自身对照组.应用彩色多普勒超声仪观察髋关节结构,监测病变区血流灌注情况.结果 Perthes病患儿病侧股骨头关节面均显示异常超声表现.彩色多普勒检查显示患侧关节囊内血流信号稀少,36例患侧股骨头骨骺终末血管及外侧颈升动脉血流速度降低.结论 超声可清楚显示Perthes病股骨头软骨及周围软组织情况,能监测髋关节细小血管的血流灌注情况.

Evaluating the hip joints' blood flow of Perthes disease with ultrasonography

Objective To investigate the value of ultrasound in evaluation of blood flow of hip joints in Perthes disease. Methods A total of 45 hip joints with Perthes'disease were examined on ultrasound imaging including color Doppler flow imaging (CDFI) in order to observe the characteristics of hip joints blood supply,while the normal hip joints in the same 45 cases were examined as the controls. Results The femoral head became flatted and broken,and rare blood signal of injured side was detected with CDFI in cases of Perthes' disease. The flow velocity of the small vessel into femoral epiphysis and the lateral ascending cervical arteries were lower than those of the controls. Conclusion Ultrasonography can correctly detect lesions and evaluate the blood supply of hip joints in patients with Perthes disease.
