摘要
在解剖学某些专著[1,2]和神经解剖学课本中[3]对小脑动脉的叙述均较简单。毛增荣[4]、钟世镇[5]、侯竞存[6]和Огнева[7]等观察过小脑动脉的发出部位、支数和管径等。Крулачев[8]与Огнев[9]研究了小脑动脉的分支和分布范围.
The cerebellar arteries including the arterial supply to the dentate nucleus had been studied on 103 Chinese brians(80 adults,23 children)by dissection,angiography,clearing method and dissection under stereoscopic microscope.The following results were obtained:1.The superior cerebellar artery which arose mostly from the upper end of the basilar artery near the posterior cerebral artery was one(82.52±2.68%)or two(17.48±2.68%)in number on each side.It was grouped into simple-trunk type(one trunk on each side 69.90±4.52%),double-trunks type(two trunks on each side 4.86±2.13%),and mixed type(one trunk on one side and two on the other 25.24±4.28%).It passed backward around the cerebral peduncle and was more frequently divided into lateral and medial branches.2.Most of the anterior inferior cerebellar arteries sprang from lower third(66.49±3.29%)and middle third(12.14±2.69%)of the basilar artery.The rest(15.06±2.69%)sprang from posterior inferior cerebellar and vertebral arteries and upper segment of the basilar artery.It was absent in 6.31±1.69%.3.The posterior inferior cerebellar artery arose mostly from the vertebral artery(77.18±2.92%)and was absent in 6.80±1.95%.It formed a loop at its original segment and gave off 1~4 branches to medulla oblongata.4.The middle inferior cerebellar artery was present in 17.48±3.95%and occurred on both sides in two cases.The course,position,distribution of all arteries mentioned above and their interrelationships were observed.5.The arteries to the dentate nucleus might be derived mainly from the superior cerebellar artery,but the anterior and posterior inferior cerebellar arteries also contributed some branches to it.These branches were found mostly 5~6 in number on the superior surface and 3~5 in number on the inferior surface.
