彩色多普勒超声诊断前臂急性骨筋膜室综合征

Color Doppler ultrasonic diagnosis of acute osteofascial compartment syndrome of forearm

目的探讨彩色多普勒超声（CDU）在前臂急性骨筋膜室综合征（OCS）诊断中的应用价值。方法前瞻性选取19例高度怀疑或确诊前臂急性OCS的患者,CDU重点观察前臂肌肉纹理回声、桡尺动脉管腔内径及多普勒频谱变化,与临床诊断及治疗措施进行相关性研究。结果16例OCS患者前臂肌肉大范围（大于1/22/3）肿胀,回声不均匀增强,肌纹理不清或消失,室内积液、血肿;桡、尺动脉管腔内径缩小;桡、尺动脉频谱出现双期双向舒张期全反向波、双期单向单相波、单期单向单相波及类静脉频谱波;阻力指数升高。结论前臂急性OCS具有特征性表现,CDU可用于前臂急性OCS的诊断。

Objective To assess the application value of color Doppler ultrasound（CDU） in the diagnosis of osteofascial copmartment syndrome（OCS） of forearm.Methods A total of 19 patients highly suspected of or diagnosed as acute OCS of forearm underwent CDU in comparison with clinical diagnosis and therapy.The echoes of muscles,the diameter and change of flow Doppler spectra of radial artery and ulnar artery were observed.Results In 16 patients of OCS,most of the forearm muscle swelled（enlarged more than 1/2-2/3 area） with the muscle echo enhanced unevenly;the textures were unclear or disappeared;and fluid or hematom appeared in muscles;and the diameter of radial artery and ulnar artery diminished.The flow Doppler spectra of radial artery and ulnar artery appeared as bid-diastolic whole inverse wave,bip-,unid-,uniph-wave,unip-,unid-uniph-wave and venous like Doppler wave.Resistance index increased.Conclusion The acute OCS of forearm has some sonographic characteristics.CDU can be used to diagnose the acute OCS of forearm.
