Two cases are reported, where intrahepatic peripheral arterial collaterals were angiographically observed. In one case the collateral artery connected the subsegmental arteries of the dorso-caudal and ventro-cranial segments; in the other collateral circulation existed between the ventro-cranial segmental artery and the middle hepatic artery. Thus, the segmental arteries of the liver are not always end arteries. A schematic drawing of the hitherto angiographically confirmed collaterals is given.
报告了两例经血管造影观察到肝内周围动脉侧支的病例。其中一例侧支动脉连接背尾段和腹头段的亚段动脉；另一例腹头段动脉与肝中动脉之间存在侧支循环。因此，肝段动脉并非总是终末动脉。给出了迄今为止经血管造影证实的侧支的示意图。
