Cerebral vasospasm (VS) and delayed cerebral ischemia (DCI) are important complications of aneurysmal subarachnoid hemorrhage (ASAH). Imaging approaches to VS monitoring include noninvasive bedside assessment with transcranial Doppler ultrasonography, angiographic evaluation with digital subtraction angiography, and computed tomography (CT) angiography. DCI is a clinical diagnosis and is not fully explained by the presence of angiographic VS. CT perfusion has shown clinical utility and implications for future research in the evaluation of DCI in patients with ASAH. This review article discusses the common approaches to diagnosis and monitoring of VS and DCI, current treatment strategies, and future research directions.
脑血管痉挛（VS）和迟发性脑缺血（DCI）是动脉瘤性蛛网膜下腔出血（ASAH）的重要并发症。VS监测的影像学方法包括经颅多普勒超声的无创床边评估、数字减影血管造影的血管造影评估以及计算机断层扫描（CT）血管造影。DCI是一种临床诊断，血管造影显示的VS并不能完全解释其发生机制。CT灌注已显示出在评估ASAH患者DCI方面的临床实用性及对未来研究的意义。本文综述讨论了VS和DCI的常见诊断和监测方法、当前的治疗策略以及未来的研究方向。
