The posterior meningeal artery, which arises from the vertebral artery, is a critical artery in neurological lesions. However, a comprehensive review of the importance of the posterior meningeal artery is currently lacking. In this study, we used the PubMed database to perform a review of the literature on the posterior meningeal artery to increase our understanding of its role in vascular lesions. The posterior meningeal artery provides the main blood supply to the paramedial and medial portions of the dura covering the cerebellar convexity. The posterior meningeal artery is often involved in dural arteriovenous fistulas occurring near the posterior fossa, and the posterior meningeal artery can be the path for transarterial embolisation or a path through which to monitor the degree of dural arteriovenous fistula embolisation. In posterior circulation ischaemia and moyamoya disease, the posterior meningeal artery can form transdural anastomoses with pial arteries at the surface of the brain, and these can help prevent ischemia. The posterior meningeal artery can also develop aneurysms, most of which are traumatic pseudoaneurysms; patients should therefore be treated in a timely manner or followed up carefully in cases of rebleeding. In addition, during a craniotomy, the posterior meningeal artery should be protected intraoperatively to avoid damaging any transdural anastomosis that may be present. In addition, when the posterior meningeal artery is the main feeding artery of an intracranial tumour, that artery is a satisfactory path for preoperative embolisation. Briefly, the posterior meningeal artery is a very important artery in neurosurgery.
脑膜后动脉起源于椎动脉，是神经病变中的一条关键动脉。然而，目前缺乏对脑膜后动脉重要性的全面综述。在本研究中，我们使用PubMed数据库对有关脑膜后动脉的文献进行综述，以加深我们对其在血管病变中作用的理解。脑膜后动脉为覆盖小脑凸面硬脑膜的内侧旁和内侧部分提供主要血液供应。脑膜后动脉常参与后颅窝附近发生的硬脑膜动静脉瘘，并且脑膜后动脉可以是经动脉栓塞的路径或监测硬脑膜动静脉瘘栓塞程度的路径。在后循环缺血和烟雾病中，脑膜后动脉可在脑表面与软脑膜动脉形成经硬脑膜吻合，这有助于预防缺血。脑膜后动脉也可形成动脉瘤，其中大多数是创伤性假性动脉瘤；因此，患者应及时治疗，或在再出血情况下仔细随访。此外，在开颅手术期间，术中应保护脑膜后动脉，以避免损伤可能存在的任何经硬脑膜吻合。此外，当脑膜后动脉是颅内肿瘤的主要供血动脉时，该动脉是术前栓塞的理想路径。简而言之，脑膜后动脉在神经外科中是一条非常重要的动脉。
