Abstract：
OBJECTIVE: Our goal was to investigate the cases of bilateral aplasia of the anterior cerebral artery (ACA).
METHODS: The macro- and microdissection of the target human brain arteries of 388 cadaveric cases was applied under the magnifying glass. Each case was photographed and diagrammatically represented in the workbook. The length and the outer diameter of the corresponding arteries on the photos were measured using a computer software program.
RESULTS: There was only one case (1/388 or 0.25%) of bilateral ACA aplasia that belonged to a male adult cadaver. Except for the variations of the posterior communicating artery on one side and the basilar artery, the instance of cerebral pathology was not recorded in this case. We compared the recent case with available literature cases.
CONCLUSIONS: Summarizing small number of literature cases, the recent case of bilateral ACA aplasia as the fifth case discovered so far, represents a true morphological rarity.

摘要：
目的：我们的目的是调查双侧大脑前动脉（ACA）发育不全的病例。
方法：在放大镜下对388例尸体的目标人脑动脉进行宏观和显微解剖。每个案件都被拍照，并在工作簿中图解表示。使用计算机软件程序测量照片上相应动脉的长度和外径。
结果：只有1例（1/388或0.25％）双侧ACA发育不全属于男性成年尸体。除一侧后交通动脉和基底动脉的变化外，在这种情况下，没有记录脑病理学的实例。我们将最近的病例与现有的文献病例进行了比较。
结论：总结少量文献案例，最近发现的双侧ACA发育不全病例是迄今为止发现的第五例，代表真正的形态稀有性。
