随着显微血管外科的普及和提高,为颅内、外动脉吻合术闭塞性脑血管的外科治疗提供形态学资料。作者于1993年11月～1995年10月用成人脑标本,对大脑中动脉的位置、走行、分支类型、口径及吻合进行了观察和测量,并对临床应用意义进行探讨。 材料与方法 用成人50例(男32例,女18例)防腐固定的完整头部和脑标本,去颅后细心地剥离蛛网膜,掰开大脑外侧裂,然后用弯脚规,直脚规,游标卡尺等观察和测量大脑中动脉主干及分支的口径、类 With the popularization and improvement of microvascular surgery, morphological data were provided for the surgical treatment of occlusive cerebrovascular in intracranial and external arterial anastomosis. From November 1993 to October 1995, the authors observed and measured the location, movement, branch type, caliber and anastomosis of middle cerebral artery using adult brain specimens. The clinical significance was also discussed. MATERIALS AND METHODS Fifty adults (32 males and 18 females) were preserved in anticorrosive, complete head and brain specimens. Exfoliative arachnoid dissection was carefully performed to separate the lateral cerebral fissure. , Vernier caliper observation and measurement of the middle cerebral artery trunk and branch caliber, class
