Cerebral hyperperfusion syndrome is a serious complication of endovascular angioplasty and stent placement for long-standing intracranial stenosis, resulting in neurologic dysfunction, seizure, or reperfusion hemorrhage. Rigorous control of blood pressure is commonly used in the perioperative period to prevent cerebral hyperperfusion syndrome, but the optimal blood pressure is often arbitrary. We describe the angiographic features that reflect impaired cerebral autoregulation and microvascular transit abnormality, which may be used to gauge the optimal blood pressure parameters in the immediate postintervention period for prevention of cerebral hyperperfusion syndrome.
大脑高灌注综合征是血管内血管成形术和支架置入治疗长期颅内狭窄的严重并发症，可导致神经功能障碍、癫痫发作或再灌注出血。围手术期通常严格控制血压以预防大脑高灌注综合征，但最佳血压通常是任意的。我们描述了反映脑自动调节功能受损和微血管转运异常的血管造影特征，这些特征可能用于评估即刻干预后预防大脑高灌注综合征的最佳血压参数。
