Methods Di ital subtraction an io raphy ( DSA) ima es of hepatic arterio raphy were retrospectively analyzed in 8 children wit h AVF. The ima in manifesta- tion of AVF w as evaluated and summarized, and the advanta e of DSA compared with ultrasound and CT w as dis- cussed. Results All 8 cases show ed clear contrast opacification in main trunk and branches of portal vein durin artery phase. Four cases that could not be dia nosed by ultrasound and 6 cases wit hout abnormality in CT w ere also dia nosed by hepatic arterio raphy. All cases were successfully treated by transarterial embolization under DSA. Conclusions Percutaneous selective hepatic arterio raphy is ef
