摘　　要：目的　评价彩色多普勒血流显像 (CDFI)对原发性肝癌患者肝动 静脉瘘 (HAVF)的诊断价值。方法　对 5 1例临床确诊原发性肝癌疑合并HAVF的患者进行CDFI检测 ,观察门静脉、肝静脉、肝动脉血流 ,观察并记录肿瘤周围及瘤体内部血流走行、形态 ,确定HAVF形成情况 ,并与DSA结果进行盲法对照。结果　CDFI诊断HAVF的敏感性、特异性、准确性、假阳性率、假阴性率、阳性预测值、阴性预测值、阳性似然比、阴性似然比、约登指数及卡帕值分别为 81.2 5 %、94.2 9%、90 .2 0 %、5 .71%、 18.75 %、 86.67%、 91.67%、 14 .2 3、 0 .2 0、0 .76及 0 .79。结论　CDFI诊断原发性肝癌HAVF的特异性及准确性较高 ,是对原发性肝癌患者HAVF早期筛选的较理想的影像学方法。Objective To evaluate the diagnostic value of color Doppler flow imaging (CDFI) on hepatic arteriovenous fistula (HAVF) in patients with hepatocelluler carcinoma. Methods Fifty one patients suspected HAVF were examined by CDFI. The results from CDFI were compared with those from digital subtraction angiography (DSA). Results In this study, the sensitivity, specificity, accuracy, false positivity rate, false negativity rate, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, Youden's index and Kappa value were 81.25%, 94.29%, 90.20% , 5.71%, 18.75%, 86.67%, 91.67%, 14.23, 0.20, 0.76 and 0.79 respectively. Conclusion The specificity and accuracy in diagnosis of HAVF by CDFI are high. CDFI is a valuable method to diagnose HAVF at early stage of hepatocelluler carcinoma.
