大脑浅静脉的显微解剖及其临床意义

Microanatomy of Superficial Cerebral Vein and Its Clinical Significance l＇i

目的：探讨大脑浅静脉的行程、分布及其吻合的解剖学特征，为临床神经外科相关手术提供形态学依据。方法：查阅近年来国内外大脑浅静脉显微解剖学的相关文献，对其行程层次、引流区域和吻合情况的相关研究成果进行分析总结。结果：大脑浅静脉依其行程层次可分为起始段、软膜段、蛛网膜下隙段、硬膜下隙段和硬膜段5段，根据引流区域大致可分为大脑上静脉、大脑中浅静脉、大脑下静脉和基底静脉4组。大脑浅静脉间存在着丰富的吻合，其中最为重要的是上、下吻合静脉。结论：熟悉大脑浅静脉的显微解剖学，有助于避免手术中损伤大脑浅静脉，减少相关并发症的发生。

Objective：To discuss the anatomical features about the course, distriblttion and anastomosis of superficial cerebral vein, to provide morphological basis for clinical neurosurgery operation. Methods： To consult and analyze the domestic and foreign literatures concerning the mieroanatomieal research of superficial cerebral vein in recent years. Results：Cerebral superficial vein can be divided into 5 segments, it contains ini- tial, pial, subarachnoid, subdural and dural segment. Cerebral superficial vein is composed groups according to the territories, named with superior cerebral vein, superficial middle cerebral vein, inferiorierebral vein and basal vein. There is a lot of vascur anastomosis between superficial cerebral veins, of which superior and inferior anastomotic veins are the most iportant. Conclusions：If we get acquaint with the superficial cerebral vein＇s microanatomy, it will be beneficial to protect superficial cerebral vein during preand intraoperative treatments and reduce complications.
