摘要
目的探讨高频超声对先天性狭窄性腱鞘炎的诊断价值。方法 46例临床疑诊先天性狭窄性腱鞘炎患者行超声检查,观察其超声图像特征。结果先天性狭窄性腱鞘炎超声表现为拇长屈肌腱于掌骨头处结节性增厚,掌指关节处A1滑车增厚,呈环状低回声,动态观察可见拇长屈肌腱在腱鞘内滑动受限。本组病例超声漏诊3例,3条先天性狭窄性腱鞘炎,超声诊断该病敏感性为93%,特异性100%,正确性94%,阳性预测值100%,阴性预测值73%。结论高频超声对先天性狭窄性腱鞘炎具有较高的诊断价值,可为临床治疗提供更为客观的依据。
Objective To explore the clinical value of high frequency ultrasound in diagnosis of congenital stenosis tenosynovitis. Methods Totally 46 patients with suspected congenital stenosis tenosynovitis were enrolled in the study. The ultrasonic examination was performed for each patient, and the characteristics of ultrasonic images were observed. Results Ultrasound examination showed that the manifestations of congenital stenosis tenosynovitis were： ①nodular thickening of the flexor pollicis Iongus muscle tendon at the palmar bone; ②the thickening of the A1 trochlear at the metacarpophalangeal joint, showing a circular hypo-echo. Dynamic observation found that the sliding of the tendon of the flexor pollicis Iongus muscle tendon was limited in the tendon sheath. Totally 3 congenital stenosis tenosynovitis in 3 patients were missed diagnosed by the ultrasound examination. The sensitivity of the ultrasound examination was 93%, the specificity was 100%, the validity was 94%, the positive predictive value was 100%, and the negative predictive value was 73%. Conclusion High frequency ultrasound had a high diagnostic value of con- genital stenosis tenosynovitis, which might provide a more objective basis for clinical treatment.
