目的:为颞叶手术避免损伤脉络丛前动脉提供解剖学依据。方法:对14具经动脉灌注红色乳胶的成人头部标本显微解剖,观察脉络丛前动脉与海马旁回钩及其前沟的关系。结果:海马旁回钩前沟至脉络丛前动脉和海马旁回钩的交点的距离左侧为(11.61±2.02)mm,右侧为(11.54±1.67)mm。结论:颞叶钩回及杏仁体、海马切除时,以海马旁回钩前沟为标志,在其后的上述距离,注意勿伤及脉络丛前动脉主干。
Objective: To provide an anatomical basis for temporal lobe surgery to prevent injury of the choroid plexus anterior artery. Methods: Twenty-four adult heads with arterial infusion of red latex were dissected and the relationship between the anterior choroid plexus and the parahippocampal gyrus and its anterior groove was observed. Results: The distance between the anterior gyrus of the hippocampus and the junction of the anterior collateral plexus and the parahippocampal gyrus was (11.61 ± 2.02) mm on the left and (11.54 ± 1.67) mm on the right. CONCLUSIONS: When the temporal lobe is uncovered and the amygdala and hippocampus are resected, the anteroposterior gyrus of the hippocampus is marked. At the following distance, attention should be given not to injure the trunk of the choroid plexus.
