CT引导下肩关节造影诊断肩关节前不稳症的价值

CT Arthrography (CTA) in the Diagnosis of Anterior Shoulder Instability

目的 :探讨CT引导下穿刺、空气 -碘水双对比造影CT诊断肩关节前不稳症的意义。材料和方法 :经临床和手术证实 5 6例为肩关节前不稳症患者 ,在CT引导下 ,行肩关节囊穿刺 ,并注入 30 %～ 35 %泛影葡胺 6～ 10ml和过滤空气10～ 2 0ml后 ,分别行仰卧位和俯卧位CT扫描 ,必要时 ,行螺旋CT扫描和 3维重建。结果 :5 6例肩关节前不稳症患者中除1例因耐药性差未检查成功外 ,其余 5 5例造影均获成功 ,16例手术患者气 碘双对比造影CT表现均与手术中所见一致。结论 :CT引导下肩关节造影可以准确诊断肩关节前不稳症并为外科手术治疗肩关节不稳症提供可靠的影像学信息。

Purpose: To describe the CT features of anterior shoulder instability in arthrography and evaluate the diagnostic value of anterior shoulder instability with CT guided puncture and double contrast CT arthrography. Materials and Methods: 56 cases of anterior shoulder instability proved by clinical data and operation were analysed. The patients were supine and prone positions and CTA obtained by 30～35% urografin 6～10ml and filtered air 10～20ml injected through an anterior shoulder puncture, if necessary, spinal CT scan and 3D reconstruction were performed. Results: All cases except one who was no toleration with urografin were examined successfully. The manifestations of arthrography of 16 cases who were undergone operation coincided with surgical operation. Conclusion: The CT arthrography is helpful in diagnosing the anterior shoulder instability and providing reliable imagiology information for surgical treatment of the anterior shoulder instability.
