Abstract：
UNASSIGNED: Circulus arteriosus cerebri (CAC), responsible for supplying blood to the brain, presents anatomical variations that have been associated with both haemorrhagic and ischemic strokes. Therefore, it is crucial to conduct comprehensive investigations and comparisons of the diverse variant components of the CAC, published in various journals, and analyze them to identify individuals at risk of cerebrovascular pathologies, thereby ensuring enhanced and timely treatment.
UNASSIGNED: A scoping review according to the five-stage protocol by Arksey and O\'Malley was performed between February and June 2023. Seven hundred and seventy-seven records were initially identified, and a total of 51 studies were finally included.
UNASSIGNED: This scoping review focuses on the anatomical variations of the CAC and their clinical implications on cerebrovascular disease and includes more original articles than review s. Consistent with previous findings, most of the records included small populations or samples, while only three records reported larger populations. Surprisingly, the populations enclosed in the included records consisted of autopsied cadaveric specimens more than living subjects. Finally, the qualitative analysis highlighted three main themes concerning the relationship between the normal CAC morphology and the cerebrovascular disease onset as well as the variant CAC morphology and its main features that might be also involved in these diseases. Finally, techniques that can be used to measure CAC have also been assessed.
UNASSIGNED: Variations in the CAC, more common in the posterior part, with genetic and environmental factors influencing these variations impact cerebrovascular disorders. Understanding variants components of CAC can aid in improving brain surgeries and post-stroke care.

摘要：
■小脑动脉环（CAC），负责向大脑供血，呈现与出血性和缺血性中风相关的解剖学变异。因此,对CAC的各种变体成分进行全面调查和比较至关重要，发表在各种期刊上，并分析它们以识别有脑血管疾病风险的个体，从而确保加强和及时的治疗。
■在2023年2月至6月之间根据Arksey和O\'Malley的五阶段协议进行了范围审查。最初确定了77条记录，最终纳入了共51项研究.
■本范围审查侧重于CAC的解剖变化及其对脑血管疾病的临床意义，并且包括比审查s更多的原创文章。与先前的发现一致，大多数记录包括小人口或样本，而只有三个记录报告了更多的人口。令人惊讶的是,纳入记录中的人群包括尸检尸体标本，而不是活体受试者。最后,定性分析强调了三个主要主题，涉及正常CAC形态与脑血管疾病发病之间的关系，以及变异的CAC形态及其可能也涉及这些疾病的主要特征。最后,还评估了可用于测量CAC的技术。
■CAC的变化，更常见于后部，遗传和环境因素影响这些变化会影响脑血管疾病。了解CAC的变体成分可以帮助改善脑部手术和中风后护理。
