作者將肝標本作動脈造影后X線檢查結果分析: (一)正常肝:以鋇蟻醛混合液充满一个30年間成人之尸體肝動脈約需6-9毫升,年齡增大時,所需之量也随之增加,可以達一倍以上,但超過20毫升则属病理现象。動脈之粗細與彈性有關;而與死前之血流量無關。老年時動脈彈性消失,動脈就變長而綣曲。肝標本動脈造影顯示的動脈有8-9級,分支呈直角或叉形。一般說來:分支角度在肝右叶之凸面最大,在其底部的次之;在左葉的最小。正常肝動脉自肝門至週圍的分布是均匀和諧的,有病變時,並不是各級動脈都有改變,在大多數情況下,病變常局限于同极大小之動脈上。作者規定1-3級分支爲大動脈;4-6級分支爲中動脈;7-9級分支爲小動脈。
The authors analyzed the liver specimens as an X-ray findings after arterial angiography: (1) Normal liver: Filling a 30-year adult cadaveric hepatic artery with a mixture of humic aldehydes takes about 6-9 ml, which is needed when the age is increased. The amount will also increase, it can be more than doubled, but more than 20 ml is a pathological phenomenon. The thickness of the arteries is related to elasticity; it has nothing to do with the blood flow before death. In the elderly, the elasticity of the arteries disappears, and the arteries grow longer and distort. Arterial angiography of liver specimens showed grades 8-9 with branches at right angles or forks. In general, the branch angle is the largest in the convex surface of the right lobe of the liver, followed by the bottom, and the smallest in the left lobe. The distribution of the normal hepatic artery from the portal of the liver to the surrounding is even and harmonious. When there is a lesion, not all the arteries at all levels are changed. In most cases, the lesion is often confined to the same-sized artery. The authors specify that the 1-3 branch is the aorta; the 4-6 branch is the middle artery; the 7-9 branch is the small artery.
