Carotid artery stenting (CAS) involves dilatation of carotid bulb which can trigger a series of neuronal responses resulting in hemodynamic depression that might influence the outcome of the procedure. This is a frequent but underdiagnosed complication of CAS. Although it is mild, transient and self-limiting in majority of cases, it can result in significant morbidity and mortality if persistent. Neurologists should be aware of the predisposing factors and management of this common complication. In patients who present with stroke following carotid stenting, neurologists should be aware of hypoperfusion secondary to hemodynamic depression as a cause of stroke apart from the stent thrombosis and occlusion.

颈动脉支架置入术后血流动力学抑制的易感因素及处理


颈动脉支架术 (CAS) 涉及颈动脉球的扩张，这会引发一系列神经元反应，导致血流动力学抑制，从而可能影响手术结果。这是 CAS 的一种常见但未被充分诊断的并发症。虽然在大多数情况下它是轻微的、短暂的和自限性的，但如果持续存在，它会导致显着的发病率和死亡率。神经科医生应该了解这种常见并发症的诱发因素和处理方法。对于颈动脉支架置入术后出现卒中的患者，神经科医生应注意继发于血流动力学抑制的低灌注也是除了支架血栓形成和闭塞之外的卒中原因。
