目的探讨儿童髋关节暂时性滑膜炎合并滑膜疝的彩色超声诊断价值。方法应用彩色超声诊断仪,频率9~4MHz、13~7MHz线阵探头,取平卧位、沿股骨颈长轴纵切和横切,二维观察髋关节前隐窝滑膜厚度、积液深度、疝囊的大小、位置、疝口直径,CDFI观察滑膜及疝囊周围软组织血供情况。结果检出髋关节暂时性滑膜炎合并滑膜疝21例,男16例,女5例;左侧17例,右侧4例;疝囊平均直径(5.17±1.54)mm,疝口平均直径(2.38±0.65)mm;血供0级11例、1级5例、2级3例、3级2例;其超声特征为患侧髋关节前隐窝滑膜不规则增厚,液性回声>2mm且积液经前关节囊呈囊状向前突出。结论儿童髋关节暂时性滑膜炎合并滑膜疝具有典型超声声像图表现,超声具有检出率高、费用低、无辐射、假阴性率低、可重复等优势,在该病诊断、鉴别诊断及疗效评价方面具有重要意义。
Objective To investigate the value of color sonography in the diagnosis of transient synovitis of synovium in children with synovial hernia. Methods The color ultrasonic diagnostic apparatus was used. The frequency of 9 ~ 4MHz, 13 ~ 7MHz line array probe was taken in supine position. The longitudinal and transection along the long axis of the femoral neck were observed. The thickness of synovial membrane, depth of effusion , Size, location of hernia sac, diameter of hernia mouth, CDFI observation of synovium and hernia sac surrounding soft tissue blood supply. Results There were 21 cases of transient synovitis and synovial hernia with 16 males and 5 females, 17 cases on the left and 4 cases on the right. The average diameter of the hernia sac was (5.17 ± 1.54) mm, the average diameter of the hernia (2.38 ± 0.65) mm. There were 11 cases of grade 0, 5 cases of grade 1, 3 cases of grade 2 and 2 cases of grade 3. The ultrasonic features were irregular thickening of synovial membrane of anterior hip, 2mm and effusion by the anterior capsule cystic forward protruding. Conclusions Temporary synovitis in synovium of hip with synovial hernia has the typical ultrasonography. Ultrasound has the advantages of high detection rate, low cost, no radiation, low false negative rate and repeatable. The diagnosis and differential diagnosis of this disease Diagnosis and efficacy evaluation of great significance.
