After hepatic artery embolization with Gelfoam powder in five rabbits, two colors of Microfil (silicone rubber solution) were perfused into the aorta and the portal vein to study hepatic microcirculation under a dissection microscope. In three of the animals, many intrahepatic arterial branches and portions of the hepatic sinusoids were perfused with the arterial Microfil (orange color), whereas in the other two animals no orange Microfil was found in the liver. In the three animals, occlusions of the hepatic artery were random in distribution and often segmental, and arteries as small as 50 microns in diameter were involved. In the latter group, levels of arterial occlusion could not be evaluated. Microcollaterals developed through the capsular artery, peribiliary arterial plexus, and vasa vasora of the portal vein.
在对5只兔子进行明胶海绵粉末肝动脉栓塞后，将两种颜色的微丝（硅橡胶溶液）注入主动脉和门静脉，在解剖显微镜下研究肝脏微循环。在其中3只动物中，许多肝内动脉分支和部分肝血窦被动脉微丝（橙色）灌注，而在另外2只动物的肝脏中未发现橙色微丝。在这3只动物中，肝动脉闭塞分布随机且常为节段性，直径小至50微米的动脉也受累。在后一组中，无法评估动脉闭塞程度。微侧支通过包膜动脉、肝门周围动脉丛和门静脉的滋养血管形成。
