Cerebral vasospasm leading to delayed cerebral ischaemia is one of the major concerns following subarachnoid haemorrhage (SAH). Various modalities are present for evaluation and detection of cerebral vasospasm that occurs following SAH. They include transcranial Doppler (TCD), computed tomographic angiography (CTA), computed tomographic (CT) perfusion and digital subtraction angiography (DSA). The recent guidelines have advocated the use of TCD and have described it as a reasonable technique for monitoring the development of vasospasm. This review describes the functioning of TCD, the cerebral haemodynamic changes during vasospasm and TCD-based detection of vasospasm. The review shall highlight as to how the TCD derived values are relevant in the settings of neurocritical care. The data in the review have been consolidated based on our search of literature from year 1981 till 2016 using various data base.
导致迟发性脑缺血的脑血管痉挛是蛛网膜下腔出血（SAH）后的主要问题之一。目前有多种方法可用于评估和检测SAH后发生的脑血管痉挛。这些方法包括经颅多普勒（TCD）、计算机断层血管造影（CTA）、计算机断层扫描（CT）灌注和数字减影血管造影（DSA）。最近的指南提倡使用TCD，并将其描述为监测血管痉挛发展的合理技术。本综述描述了TCD的功能、血管痉挛期间的脑血流动力学变化以及基于TCD的血管痉挛检测。该综述将强调TCD得出的值在神经重症监护环境中的相关性。本综述中的数据是基于我们使用各种数据库搜索1981年至2016年的文献而整理的。
