急性缺血性卒中患者恶性脑水肿的影像学预测因素

Imaging predictors of malignant cerebral edema in patients with acute ischemic stroke

恶性脑水肿可导致颅内压增高、神经功能迅速恶化甚至脑疝形成,具有高致死率和高致残率的特点,是急性大面积脑梗死患者预后不良的常见原因。早期行去骨瓣减压术可有效改善恶性脑水肿患者的神经功能转归。因此,对恶性脑水肿的早期预测至关重要。文章就恶性脑水肿的形成机制及其相关影像学表现进行综述,以期为大面积脑梗死后恶性脑水肿的早期诊断和合理治疗提供参考和帮助。

Malignant cerebral edema can lead to increased intracranial pressure,rapid deterioration of neurological function,and even the formation of cerebral hernia.It has the characteristics of high mortality and disability rates,and is a common cause of poor prognosis in patients with acute massive cerebral infarction.Early decompressive craniectomy can effectively improve the neurological outcomes of patients with malignant cerebral edema.Therefore,early prediction of malignant cerebral edema is crucial.This article reviews the formation mechanism and related imaging manifestations of malignant cerebral edema,in order to provide reference and assistance for the early diagnosis and reasonable treatment of malignant cerebral edema after massive cerebral infarction.
