MICROANATOMY OF THE MESENCEPHALIC VEINS OF THE CHINESE / 解剖学报

ABSTRACT

A new method known as continuous arterio-venous perfusion and clearing of thick sections according to Mulligan's procedure Were applied. After the vessels of the mesencephalon were perfused, arteries revealed red colour and the -veins blafck. Under SXP-1 stereo-microscope, the morphology, rate of occurrence, tributaries and drainage of the interpeduncular veins, the posterior communicating vein, the lateral peduncular veins, the circumpeduncular veins, the veins of the pontomesencephalic sulcus, the lateral mesencephalic veins, the veins of the brachium conjunctivum, the precentral cerebellar vein and the quadrigeminal veins of 27 (54 sides) adult mesencephala were observed. The origin, course, drainage and outlet of internal veins such as antero-medial, anterolateral, lateral and posterior veins of 10 adult mesencephala were investigated and compared with 3 venograms of mesencephalon from other specimens. The clinical significance of some of the above vessels were discussed.
