The supracerebellar infratentorial approach (SCITA) is a standard approach used in a neurosurgical practice. It carries some risk of associated complications including cerebellar venous infarction with possible serious sequelae. The objective of this study is to address the incidence of cerebellar venous infarction in SCITA. A search through the currently available literature was performed in September 2019 from the year 2000 until September 2019 dealing with ‘supracerebellar infratentorial approach’. Out of the 578 patients found in thirteen case series, two venous infarctions were present; the remaining four patients were published as case reports. By analysing the case series, we calculated the risk of such a complication to be 0.345% (95% CI [0.061%, 1.248%]). Case reports were not included. The real risk is estimated to be higher. The risk of cerebellar venous infarction is an unpredictable, infrequent but real complication with potentially dreadful sequelae. Each neurosurgeon using this approach should be aware of this event when employing this approach. The avoidance of cerebellar venous infarction can be lowered by leaving as many bridging veins intact as possible.

肩上腓下肌入路（SCITA）是在神经外科实践中使用的标准方法。它带有一些相关并发症的风险，包括小脑静脉梗塞和可能的严重后遗症。这项研究的目的是解决SCITA中小脑静脉梗塞的发生率。在2000年9月至2019年9月期间，对涉及``上小脑下肌腱鞘入路''的文献进行了搜索。在13个病例系列中发现的578例患者中，有2例发生了静脉梗塞。其余四名患者作为病例报告发表。通过分析病例序列，我们计算出这种并发症的风险为0.345％（95％CI [0.061％，1.248％]）。病例报告不包括在内。实际风险估计更高。小脑静脉梗塞的风险是不可预测的，不常见的，但真正的并发症是潜在的可怕后遗症。使用这种方法的每个神经外科医生在使用这种方法时都应该意识到这一事件。小脑静脉梗塞的避免可以通过尽可能多地保留完整的桥接静脉来降低。
