前交通动脉常由于解剖变异及血管痉挛,在血管造影时不能充分显影。此外动脉硬化性弯曲和拉长也可改变正常形态。在该部位动脉瘤手术中忽视这些微动脉和小动脉,有可能造成性格改变、记忆缺陷、偏瘫、失语、视野缺损、甚至死亡。因此研究前交通动脉及其附近显微血管关系对前交通动脉瘤手术甚为重要。现在通过放大技术,在剥离动脉瘤时已能看清并保留邻近的小动脉。最近 Perlmutter 和Rhoton 对50例成人尸体的脑部以及大脑前动脉、前交通动脉、回返动脉群及其小分支的
Anterior communicating artery often due to anatomical variations and vasospasm, angiography can not be fully developed. In addition, arteriosclerosis and elongation can also change the normal morphology. Ignoring these arterioles and arterioles in aneurysm surgery at this site may result in personality changes, memory deficits, hemiplegia, aphasia, visual field defects, and even death. Therefore, the study of the anterior communicating artery and its adjacent microvascular relationship is very important for anterior communicating artery aneurysm surgery. Now through the magnification technique, we can see and retain the adjacent arterioles when dissecting the aneurysm. Recently, Perlmutter and Rhoton treated the brains of 50 adult cadavers, as well as the anterior cerebral arteries, the anterior communicating arteries, the group of returning arteries and their small branches
