国人中脑静脉的显微解剖

MICROANATOMY OF THE MESENCEPHALIC VEINS OF THE CHINESE

本文报道采用动-静脉连续灌注法,区别动、静脉。经厚切片透明,在SXP-1手术显微镜下观察了27例(54侧)成人中脑浅层的脚间静脉、后交通静脉、大脑脚外侧静脉、旋大脑脚静脉、脑桥中脑沟静脉、中脑外侧静脉、结合臂静脉、小脑前中央静脉和四叠体静脉的形态、出现率、收集属支及汇流情况。还观察了10个中脑内部静脉的中脑前内侧、前外侧、外侧和后静脉的起始、行程、穿出点和汇流情况。同时作了3个中脑静脉造影作为对照,并结合临床进行了讨论。

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.
