颅内静脉窦血栓形成(CVST)是指颅内静脉窦血栓形成,引起窦腔狭窄闭塞,脑静脉血回流和脑脊液吸收障碍,继而引起脑水肿、脑卒中及颅内压增高等一系列病理生理改变以及相应局灶症状的一种疾病。因临床表现多样、缺乏特异性症状及体征而易漏诊、误诊,在临床上主要靠颅内压增高的症状、影像学改变等来确立诊断。目前治疗仍以抗凝为主,大部分患者疗效肯定;对于抗凝无效甚至危重CVST患者近年来有报道予以 Intracranial sinus thrombosis (CVST) refers to intracranial venous sinus thrombosis, causing sinus cavity occlusion, cerebral venous return and cerebrospinal fluid imbalance, and then lead to cerebral edema, stroke and increased intracranial pressure and a series of pathophysiology Change and the corresponding focal symptoms of a disease. Due to the diversity of clinical manifestations, the lack of specific symptoms and signs and easy to misdiagnosis, misdiagnosis, clinically mainly rely on increased intracranial pressure symptoms, imaging changes to establish the diagnosis. The current treatment is still mainly anticoagulant, the majority of patients with definite effect; for anticoagulant invalid or even critically ill CVST patients reported in recent years
