Eleven arteriograms, 7 corrosion casts, and 40 dissection studies of 51 clinically normal dogs were examined for the branching patterns of the hepatic artery. An injection of radiopaque medium for selective arteriography was made initially to radiograph the celiac artery, after which a technique defined as superselective arteriography was done, advancing a catheter tip into the hepatic artery. Superselective arteriograms for study of the hepatic artery are described, and the anatomic variants of its branching are discussed. Three major types of hepatic artery branching patterns were identified. The first consists of a single hepatic artery trunk, and this pattern was found in four dogs. The second type with two separate branches of the hepatic artery was found in 27 dogs. The third type was seen in 20 dogs and consisted of 3, 4, or 5 branches that originated directly from the hepatic artery. The origin of the right gastric artery varied, as did the branching of the celiac artery. The most common termination of the celiac artery was as two branches in 31 dogs, and these branches were the hepatic artery and a gastrosplenic trunk. The gastrosplenic trunk subsequently divided to form the left gastric artery and the splenic artery. The usual description of the celiac artery is that it ends by trifurcating. A scheme was developed in which the three major types of hepatic artery branching patterns were outlined. This scheme encompases the hepatic lobar artery variants and can serve as a basis for interpretation of detailed hepatic arteriograms.
对51只临床正常犬的11份动脉造影片、7个铸型标本和40份解剖研究进行了检查，以观察肝动脉的分支模式。最初注入不透射线的造影剂进行选择性动脉造影，以拍摄腹腔动脉的X线片，之后采用一种定义为超选择性动脉造影的技术，将导管尖端推进肝动脉。描述了用于研究肝动脉的超选择性动脉造影片，并讨论了其分支的解剖变异。确定了三种主要的肝动脉分支模式。第一种模式由单一的肝动脉主干组成，在4只犬中发现了这种模式。第二种模式是肝动脉有两个独立分支，在27只犬中发现。第三种模式在20只犬中可见，由直接起源于肝动脉的3、4或5个分支组成。胃右动脉的起源各不相同，腹腔动脉的分支也如此。腹腔动脉最常见的终末形式是在31只犬中分为两个分支，这些分支是肝动脉和胃脾干。胃脾干随后再分支形成胃左动脉和脾动脉。腹腔动脉通常的描述是它以三分叉结束。制定了一个方案，概述了肝动脉分支的三种主要模式。该方案涵盖了肝叶动脉变异情况，可作为解释详细肝动脉造影片的基础。
