超声造影在胸壁结核穿刺活检中的应用价值

Application value of contrast-enhanced ultrasound in chest wall tuberculosis puncture biopsy

目的总结超声造影后穿刺活检阳性率,探讨超声造影在胸壁结核穿刺活检中的应用价值。方法收集2013年11月~2015年12月的70例胸壁肿块患者,按照历史对照法分为对照组(30例)和研究组(40例)。对照组常规超声引导下行穿刺活检术,研究组经超声造影后,确定取材区,行超声引导下穿刺活检术,比较两组的活检组织完整率和病理阳性率。结果对照组的活检组织完整率为43.3%,病理诊断阳性率为76.7%;研究组的活检组织完整率为87.5%,病理诊断阳性率为100.0%。研究组的活检组织完整情况优于对照组,病理诊断阳性率高于对照组,差异有统计学意义(P<0.05)。结论超声造影应用于胸壁结核性脓肿穿刺活检可显示胸壁结核的血供特点,能够提高取材完整率和病理诊断阳性率,具有较高的应用价值。

Objective To summarize the positive rate of biopsy after contrast-enhanced ultrasound,and to explore the application value of contrast-enhanced ultrasound in chest wall tuberculosis puncture biopsy.Methods 70 patients with thoracic wall mass from November 2013 to December 2015 were selected,all patients were divided into the control group （30 cases） and the study group （40 cases） according to historical comparison method.The control group was used general ultrasound guided puncture biopsy,the study group was determined by ultrasound contrast to determine the area, then the ultrasound guided biopsy was performed.The sample complete rate and pathological positive rate were cornpared between the two groups.Results The sample complete rate was 43.3% and pathological positive rate was 76.7% in the control group,which were respectively 87.5%,and 10010% in the study group.The sample complete situation in the study group was better than that in the control group,the pathological positive rate in the study group was higher than that in the control group,with significant difference （P〈0.05）.Conelusion Contrast enhanced ultrasound in puncture biopsy of chest wall tuberculous abscess can show the characteristics of chest wall tuberculosis blood supply,have higher sample complete rate and pathological positive rate,and have higher application value.
