The aim of this study was to establish selective hepatic artery catheterization technique through percutaneous femoral artery puncture and to offer digital subtraction angiography(DSA) of hepatic artery in beagle dogs. Percutaneous femoral artery puncture was performed with Sheldinger's method. Microferret TM- 18 Infusion catheter(William, Cook, Europe) was introduced into abdominal aorta. Then, under fluoroscopy, iopamidol 370(Bracco, Italy) was injected to identify celiac artery and `J' shpaed guide wire was introduced into celiac artery. Catheter could be introduced into celiac artery through guide wire. In this manner, catheter was located at the insertion of hepatic artery and DSA was performed. In DSA of beagle dogs, hepatic artery which was divided into lateral branch, right-medial branch, right-lateral branch of hepatic artery, cystic artery and gastroduodenal artery was opacified without superimposition of any other body structure and so was the parenchyme of liver afterward. In autopsy angiographic finding of resected liver, cystic artery, caudate branch, lateral branch, right-medial branch, right-lateral branch and quadrate branch of hepatic artery were identifed. It was concluded that selective hepatic artery catheterization technique was a minimally invasive method that facillitated the approach of hepatic artery and DSA was an excellent tool to visualize the vessle of liver in dogs.
