摘要目的探讨超声及声触诊组织量化(VTQ)技术在囊型肝包虫囊肿内容物活性判断中的应用价值。方法通过超声检查和VTQ技术,检测48例经手术病理证实的51个囊型肝包虫囊肿声像图特征及囊内容物的Vs值,并结合病理学检查资料进行比较分析 。结果囊型肝包虫超声分型中,内囊分离型和实变型分别与单纯囊肿型和子囊型比较,Vs测量阳性率均增高(P<0.05);无活性原头蚴组Vs测量阳性率比有活性原头蚴组显著增高(P<0.001);病理学分级中,Ⅲ级分别与I级及Ⅱ级比较,Vs测量阳性率均增高(P<0.05);内囊破裂组Vs测量阳性率显著高于内囊完整组(P<0.001)。结论VTQ技术结合超声声像图,在囊型肝包虫内容物活性预测中具有较高的临床应用价值。

AbstractObjectiveTo evaluate the value of liver hydatid cyst in the ultrasound and virtual touch tissue quantification(VTQ)in determination of the viability of liver hydatid cyst.Methods 48 cases with 51 hepatic hydatid cysts confirmed by the operation and pathology underwent conventional sonography,then analyzed and compared the ultrasonogram and the shear wave velocities(Vs)and the pathological data.Results According sonographic type,the positive rate of Vs values in the separated endocyst cyst type and the solid cyst type was higher than in the simple cyst type and the daughter cyst type(P<0.05).The positive rate of Vs values in the non active protoscolex group was higher than in the active protoscolex group(P<0.001).According pathological grade of the endocyst,the positive rate of Vs values in Ⅲ grade group was higher than inIand Ⅱ grade groups(P<0.05).The positive rate of Vs values in the rupture endocyst group was higher than in the complete endocyst group(P<0.001).Conclusion Ultrasound and VTQ could play a crucial role in judging viability for preoperative prediction and the different development periods of liver hydatid cyst .

手术前明确囊型肝包虫病囊内容物的病理学变化和活性程度,对治疗方案的选择、治疗效果的观察及预后的评价有很大的帮助[1]。本研究探讨超声及声触诊组织量化(Virtual Touch Tissue Quantification,VTQ )技术在囊型肝包虫病囊内容物活性判断中的应用价值。
1材料与方法
1.1 研究对象
2013年1月至2015年1月青海省人民医院住院诊治,并经手术和病理学证实的囊型肝包虫患者48例[男20例,女28例,年龄18岁~74岁,平均年龄(39.0±12.9)岁],肝包虫囊肿51个(单纯囊肿型11例、子囊型10例、内囊分离型13例、实变型14例)。
1.2 研究方法
1.2.1仪器与测量:采用Siemens Acuson S-2000彩色超声仪(配有VTQ技术软件)。将仪器设置为Abdmon条件,采用4C-1凸阵探头,频率(2~4)MHZ。先进行肝脏常规超声扫查,获取肝包虫囊肿的部位、大小、形态、边缘、内部回声、有无血流等图像特征,然后将仪器调到VTQ模式,扫查肝包虫囊肿,深度不超过5.5 cm,且避开囊肿外血管和气体干扰。……
