摘要
目的分析肝癌合并动脉门脉瘘的多层螺旋CT(MSCT)表现及肿瘤的生长方式、大小与动脉门脉瘘(APF)的关系,评价MSCT在诊断APF的价值。方法回顾性分析86例肝癌患者的MSCT和DSA表现。结果①86例肝癌患者MSCT检查发现APF 36处,DSA检查发现33处。与DSA相比,MSCT检查的敏感度为90.9%,特异度为88.7%,阳性预测值为83.3%,阴性预测值为94%;②肝癌合并APF的几率与肿瘤的生长方式有相关性,与肿瘤的大小无相关性。结论MSCT对肝癌合并APF的正确诊断很有价值,可作为肝癌治疗前进行综合评估的检查方法。
Objective To evaluate the value of multi-slice spiral CT （MSCT） for intrahepatic arterioportal fistula by analyzing the MSCT features of arterioportal fistula （APF） associated with hepatocellular carcinoma （HCC）, and discuss the correlation between APF and growth type of tumor, size of tumor. Methods Eighty six cases of HCC were examined by MSCT and DSA. Results Of 86 patients with HCC, 33 were demonstrated to have APF on DSA, 36 had positive CT findings. The sensitivity, specificity, positive and negative predictive value of MSCT in diagnosing APF was 90. 9%, 88. 7%, 83.3%, 94%, respectively. The incidence of APF in HCC was correlative with growth type of tumor, and was not with size of tumor. Conclusion MSCT is very important in the diagnosis of APF. It can be used as an imaging method for comprehensive assessment of hepatocellular carcinoma before treatment.
