目的:研究大脑后动脉分支及走行。方法：在手术显微镜下放大４—６０倍，观察５８例１１６侧大脑后动脉及其分支走行。结果：大脑后动脉Ｐ１段左侧稍粗于右侧，Ｐ２、Ｐ３段管径左右变化较大，主要与后交通动脉的管径有关。大脑后动脉皮质支可分为：单干型、双干型、三干型、四干型和五干型。颞下前动脉和颞下中动脉合干起于颈内动脉尚属首见。结论：大脑后动脉供应枕叶的大部分和颞叶的底面，以及参与形成第三脑室的脉络丛。
Objective: To study the posterior cerebral artery branches and walk. Methods: Magnified 4-60 times under the operating microscope, 58 cases of 116 posterior cerebral arteries and their branches were observed. Results: The left posterior cerebral artery was slightly thicker on the left side of the left, and the diameters of the proximal and distal arterial branches varied greatly in the P2 and P3 segments, which were mainly related to the diameter of the posterior communicating artery. Posterior cerebral artery cortical branch can be divided into: single-type, double-type, three-type, four-type and five-type dry. Temporomandibular artery and infraorbital middle artery occlusion stem from the internal carotid artery is the first to see. Conclusion: The posterior cerebral artery supplies most of the occipital lobe and the bottom of the temporal lobe, as well as the choroid plexus involved in the formation of the third ventricle.
