CT在肝癌介入治疗中的应用价值

Application value of CT in interventional therapy of liver cancer

目的探究比较C型臀CT机与常规数字减影血管造影(DSA)技术在肝癌介入治疗中的临床应用价值。方法选取该院2013年8月30日至2016年8月30日收治的行肝癌介入治疗患者80例作为研究对象,对80例患者在肝癌介入治疗过程中给予C型臀CT机和常规DSA检查,并记录2种检查方法对病灶位置、肿瘤实质、供血血管情况及术后对碘油沉积部位的显示情况。结果 80例患者中C型臀CT机检查发现肿瘤病灶123个,肿瘤大小(2.81±0.36)cm;常规DSA检查发现肿瘤病灶116个,肿瘤大小(2.87±0.84)cm。C型臀CT机检查的肿瘤大小与常规DSA检查比较,差异无统计学意义(t=0.725,P>0.05);C型臀CT机检查较常规DSA检查多发现7个病灶(7/123,5.69%),且C型臀CT机检查可清楚反映肝脏及肿瘤供血血管数量为197条,较常规DSA检查多68条。介入治疗后C型臀CT机检查出的123个病灶全部显示,常规DSA检查显示120个病灶(120/123,97.56%)。C型臀CT机检查显示碘油沉积1、2级者达94.31%(116/123),常规DSA检查显示碘油沉积1、2级者达82.11%(101/123),二者比较,差异有统计学意义(χ2=7.156,P<0.05)。结论 C型臀CT机检查可有效帮助医生在肝癌介入治疗中明确肿瘤位置,帮助其了解和掌握肿瘤供血血管情况,且对治疗后患者碘油沉积等情况进行详细成像和显示,是肝癌介入治疗最有效的检查设备之一,值得临床推广应用。

Objective To explore the clinic application value of C hip with conventional CT digital subtraction angiography（DSA） technique in the clinical value of the treatment of liver cancer. Methods Eighty patients undergoing interventional treatment of hepatocellular carcinoma from August 30,2013 to August 30,2016 were selected. Type C hip CT and conventional DSA examination were performed and the lesion location, solid parts of tumor, blood vessels and the indication of lipiodol deposition. Results Among 80 patients,type C hip CT examination found 123 lesions of tumor,the tumor size was（2.81±0.36）cm while conventional DSA examination found 116 lesions of tumor,the tumor size was（2.87±0.84）cm. The difference of tumor size measured by conventional DSA examination and C type CT examination of the hip has no statistically significant（t=0.725,P0.05）.The type C hip CT examination scanned 7 lesions（7/123,5.69%） more than conventional DSA examination. The C hip CT examination clearly reflected liver and tumor blood vessel number was 197,which was 68 vessels more than conventional DSA examination. After interventional treatment of type C hip CT scanning,all the 123 lesions were showed and the conventional DSA examination revealed 120 lesions（120/123,97.56%）. Type C hip CT examination showed that the deposition of lipiodol in grade 1 and2 was 94.31%（116/123）,conventional DSA examination showed that the lipiodol deposition grade 1 and 2 was 82.11%（101/123）,the difference was statistically significant between the two groups（χ2=7.156,P0.05）. Conclusion Type C hip CT scanning can effectively help doctors to confirm the location of the tumor in the interventional therapy of liver cancer and help them to grasp the blood supply of tumor,as well as providing detailed images and display with lipiodol deposition etc. after treatment. It is the most effective equipment of liver cancer,which is worthy of further clinical applications.
