本文报道用体视显微镜和光学显微镜在46例成人脑标本上观察并测量了松果体的动脉,在10例标本上观察了松果体的静脉。松果体的动脉依数目可分为单支、双支、三支和多支四种类型。其中单支型占54.55％,双支型占34.09％。动脉的主要来源为脉络膜后内侧动脉,占69.72％;其次为四叠体动脉,占28.87％。仅有一个动脉来源者占76.14％,有上述双重动脉来源者占23.86％。松果体动脉起点部位多在上丘与松果体间隐窝内(占46.67％),少数在上丘外侧或胼胝体压部下方等处。其行程长度为0.2～38.4 mm,向前或向内走行,多数在松果体体部侧方入腺体。然后在松果体囊上、囊外或囊内实质表面分支,分布于腺体。按其分支形式可分四种类型、10种亚型。动脉管的外径平均0.30±0.08 mm,内径平均0.21±0.07 mm。松果体的静脉有一对主干——脉络膜松果体静脉。它起自第三脑室脉络丛,向后经松果体腹外侧,收集同侧的松果体背侧和腹侧静脉,末端在松果体顶部两侧会合成松果体奇静脉或分别注入大脑大静脉。
The paper reports the observation and measurement of the pineal artery in 46 adult human brain specimens with stereomicroscope and optical microscope, and the observation of the pineal veins in 10 specimens. Pineal artery according to the number can be divided into single, double, triple and multi-branch four types. Among them, 54.55% were single type and 34.09% were dual type. The main source of artery was choroidal medial artery, accounting for 69.72%; followed by the quadrigeminal artery, accounting for 28.87%. Only one arterial source accounted for 76.14%, with the above-mentioned dual arterial source accounted for 23.86%. The origin of pineal artery artery mostly in the site of crypt and pineal crypts (46.67%), a few in the lateral hypothalamus or corpus callosum below. The length of its travel is 0.2 ~ 38.4 mm, walking forward or inward, most of the side of the pineal body into the gland. Then in the pineal capsule, extracapsular or intracapsular parenchyma surface, located in the gland. According to the form of its branches can be divided into four types, 10 subtypes. The average arterial diameter was 0.30 ± 0.08 mm and the average diameter was 0.21 ± 0.07 mm. Pineal veins have a pair of trunk - choroidal pineal veins. It starts from the choroid plexus of the third ventricle and passes rearward through the ventrolateral side of the pineal gland. The dorsal and ventral veins of the pineal gland are collected on the same side. Great vein of the brain.
