Cerebral vasospasm and delayed cerebral ischemia represent a very challenging aspect of cerebrovascular pathophysiology, most commonly subarachnoid hemorrhage, with significantly high mortality if left untreated. Considerable advances have been made in medical treatment and prompt diagnosis, while newer endovascular modalities have recently been proposed for cases of resistant cerebral vasospasm. However, there is still paucity of data regarding which and whether a single endovascular technique is non inferior to the pharmacological standard of care. In this review, we aim to summarize the current funds of knowledge concerning cerebral vasospasm and the emerging role of the endovascular techniques for its treatment.

不断发展的前沿：治疗迟发性脑缺血的血管内策略

脑血管痉挛和迟发性脑缺血是脑血管病理生理学中非常具有挑战性的一个方面，最常见的是蛛网膜下腔出血，如果不及时治疗，死亡率会很高。在医学治疗和及时诊断方面已经取得了相当大的进步，最近针对顽固性脑血管痉挛病例提出了新的血管内治疗方法。然而，关于哪种血管内技术以及是否不低于药理学护理标准的数据仍然缺乏。在这篇综述中，我们的目的是总结当前有关脑血管痉挛的知识储备以及血管内技术在其治疗中的新兴作用。
