人丘脑内部的血管配布

THE DISTRIBUTION OF INTRATHALAMIC VESSELS IN HUMAN BRAIN

应用动-静脉连续灌注法,厚薄交替连续切片,厚片透明,薄片染色,观察了8侧新生儿丘脑内部动、静脉的走行与配布。丘脑各核团的动脉供应主要有丘脑穿动脉、膝状体丘脑动脉、脉络丛后内动脉、枕下内侧动脉和侧脑室脉络丛动脉,其中丘脑穿动脉还分布到丘脑腹前核、带旁核和网状核。丘脑的静脉分别汇入大脑内静脉、侧脑室静脉、脚间窝静脉和基底静脉。动、静脉的走行关系为独立、伴行及数条动脉围绕一条静脉等形式。本文还讨论了观察结果对丘脑血管梗塞临床诊断的意义。

The course, distribution of the intrathalamic vessels on 8 sides of newborn brains were studied by means of the continuous artery-vein infusion, Spalteholz's clearing and Nissl's staining. The brains were all cut into the coronal sections of 500 μm, 100μm and 30μm thickness in alternate and successive order. The main arteries supplying thalamic nuclei were: 1. The thalamoperforating artery; 2. The geniculothalamic artery; 3. The medial posterior choroidal artery; 4. The medial inferior pulvinar artery; 5. The lateral ventricular choroidal artery. The thalamic veins opened respectively into the internal cerebral vein, the veins of the lateral ventricle, the veins of the interpeduncular fossa and the basal vein. There were three patterns of course relation between thalamic arteries and veins. They were solitariness, accompanying and one vein surrounded by several arteries.
