颅内静脉系统血栓形成(cerebral venous sinus thrombosis，CVST)是指由于多种病因引起的以脑静脉回流受阻、常伴有脑脊液吸收障碍导致颅内高压为特征的特殊类型脑血管病，在脑血管病中约占0.5%～1% 。

2011年2月3日 · Thrombosis of the dural sinus and/or cerebral veins (CVT) is an uncommon form of stroke, usually affecting young individuals. 1 Despite advances in the recognition of CVT in recent years, diagnosis and management can be difficult because of the diversity of underlying risk factors and the absence of a uniform treatment approach.

2010年10月21日 · Clinically patients with cerebral venous thrombosis present with variable symptoms ranging from headache to seizure and coma in severe cases. In neonates shock and dehydration is a common cause of venous thrombosis. In older children it is often local infection, such as mastoiditis, or coagulopathy.

2024年3月7日 · 目的 探讨颅内静脉窦血栓 (CVST)的临床诊 断中，使用三维时间飞跃法磁共振血管成像 (3D-TOF MRA)协助诊断的临床应用价值。 方法 选取我院22 例CVST患者，共154个静脉窦节段的MRI资料。 分 析3D-TOF MRA CVST信号特点，评估3D-TOF MRA对 CVST显示的价值。 结果 以DSA结果为标准，22例共 发现存在CVST的静脉窦节段67个，PC-MRV正确识别 57个，3D-TOF MRA正确识别54个。 3D-TOF MRA上 CVST可表现为等信号 (13个)、高信号 (35个)或混 …

2016年12月11日 · On MRI, CVST presents with rather complex MRI sequence-dependent signal abnormalities, which also vary significantly between the different stages of the disease. Depending on the age of the thrombotic material, an acute, subacute, and chronic stage of CVST can be distinguished which all present with different signal characteristics which are ...

2024年8月1日 · CVST is a rare disorder more common in the pediatric population, especially in neonates. Presenting signs and symptoms are nonspecific and include headache, lethargy, altered mentation, vomiting, or focal neurological deficits. Imaging is crucial for diagnosing and determining CVST location.

本文从cvst的流行病学、病因学、临床与病理入手，重点介绍了cvst特征性ct、mri及dsa表现，并根据其影像表现初步判断预后。 CVST早期准确诊断，对指导临床精准治疗及预后评估具有重要意义。

2019年8月22日 · Cerebral venous and sinus thrombosis (CVST) is an important cause of stroke, especially in young patients and children, resulting from clot formation and propagation leading to the occlusion of intracranial venous system components, including the dural sinuses, the cortical veins, and the proximal segment of the jugular veins.

Results: MRI and MRA together provided the diagnosis of CVT in all cases. The sensitivity of MRI alone was 90%. MRA showed abnormalities in all cases of CVT. Progressive sinus recanalization was demonstrated by follow-up with MRI and MRA at least 15 days after diagnosis and treatment.
