Application of Doppler ultrasonography in detection of hepatocellular carcinomaassociated hepatic arteriovenous fistula
【Abstract】 AIM: To investigate the ultrasonographic characteristics and hemodynamics of hepatocellular carcinomaassociated hepatic arteriovenous fistula (HAVF) and evaluate the capability of twodimensional and Doppler ultrasonography in detection of HAVF. METHODS: Seventyeight patients diagnosed as hepatocellular carcinoma were enrolled in this study. The portal and hepatic veins, hepatic arteries and vessels around and inside the tumor were detected and the hemodynamic indices were recorded with ultrasonography. The results from Doppler were compared with those from digital substraction angiography (DSA). Ten patients with HAVF were followed up after the therapy of arterial embolization. RESULTS: ① Twentyfive HAVF were detected by Doppler. The sensitivity, specificity, accuracy, falsepositive rate and falsenegative rate were 83.33%, 90.74%, 88.46%, 9.26% and 16.67%, respectively. ② The diameters of hepatic artery of patients with HAVF were larger than those of patients without HAVF ［（0.42±0.09） cm vs （0.36±0.09） cm，P
