作者在放大4~9倍的手术显微镜下对国人50例脑干各部动脉的起源、分布、支数及吻合情况进行了详细的观察,并对各组动脉闭塞所产生的脑干梗塞综合征作了联系与探讨。延髓腹侧主要由脊髓前动脉的分支供应,椎动脉的分支及盲孔支可作补充。椎动脉、小脑下后动脉的延髓外侧支在延髓外侧的血供中占主要地位,血管的阻塞可引起延髓外侧综合征。小脑下后和脊髓后动脉的分支组成后组供应延髓背侧。脑桥腹侧主要由基底动脉的旁正中动脉(4支)供应。脑桥外侧由基底动脉的短旋动脉(5支)、小脑下前及小脑上动脉的脑桥支组成的外侧组供应的,互相在三叉神经根周围吻合。脑桥背侧由基底动脉的长旋动脉(1~3支)和小脑上动脉的分支供应。小脑下前和小脑上动脉不仅供应小脑,它们在脑桥的血供中也很重要,血管的阻塞或结扎可导致脑干局部梗塞。中脑腹侧由脚间窝支、小脑上和大脑后动脉的中脑前支组成的前组动脉供应。中脑外侧由小脑上和大脑后动脉的中脑外侧支供应。中脑背侧(顶盖)由小脑上和大脑后动脉的中脑后支供应,血管在四叠体表面吻合成网。中脑血管的病变也可引起中脑不同区域的综合征。
The authors observed the origin, distribution, count and anastomosis of 50 brainstem arteries of Chinese people under the magnification of 4 ~ 9 times under the operating microscope. The cerebral infarction syndrome caused by arterial occlusion The contact and discussion. Ventral medulla mainly by the branch of the anterior spinal artery supply, branch of the vertebral artery and blind hole branch can be added. The lateral branches of the medulla oblongata in the vertebral artery and the posterior inferior cerebellar artery dominate the blood supply outside the medulla oblongata, and the obstruction of the blood vessels can cause medullary lateral syndrome. The posterior cerebellar and posterior spinal artery branches constitute the posterior group of medulla oblongata. The ventral pontine is mainly supplied by the mid-artery of the basilar artery (4 branches). Lateral pons are provided by the lateral group consisting of the basilar artery short spinous arteries (5 branches), the inferior cerebellar superior and the superior cerebellar branches of the superior cerebellar artery, and are mutually anastomosed around the trigeminal nerve roots. The dorsal pons are supplied by the basilar artery’s long spinous artery (1 to 3 branches) and the branch of the superior cerebellar artery. The inferior cerebellar superior and superior cerebellar arteries supply not only the cerebellum, they are also important in the blood supply to the pons and the occlusion or ligation of blood vessels can lead to a partial infarction of the brainstem. The anterior ventral aspect of the midbrain is composed of a forearm artery composed of anterior branch of the foot, supraoptic cerebrum and posterior cerebral artery. The medial midbrain is supplied by the lateral midbrain of the supraoptic and posterior cerebral arteries. The midbrain dorsal (cap) is supplied by the posterior midbrain of the supraoptic and posterior cerebral arteries, and the blood vessels mesh on the surface of the quadruplex. Cerebral vascular lesions can also cause different regions of the brain syndrome.
