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.

2025年3月12日 · Cerebral venous thrombosis (CVT) (plural: thromboses) refers to the occlusion of venous channels in the cranial cavity, including dural venous thrombosis, cortical vein thrombosis and deep cerebral vein thrombosis. They often co-exist and the clinical presentation among them is very similar and non-specific.

2024年1月29日 · Contrast-enhanced MRV, gradient-recalled echo, or susceptibility-weighted imaging sequences are the recommended techniques for the diagnosis of cortical venous thrombosis. (New) The mainstream initial treatment of CVT includes parenteral heparin followed by transition to oral VKAs for 3 to 12 months, depending on the underlying cause, or ...

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% 。

With recent advancement in technology, CTV and MR venography (MRV) have now replaced digital subtraction cerebral angiography as the diagnostic test of choice for CVST. [4, 7, 8, 9] Hyperdense sign of venous sinuses on NCT scan has a sensitivity of 84% and 95% and specificity of 96% and 95% with a HU (Hounsfield unit) cut-off value of 65 and 62,...

2018年7月1日 · Several studies have suggested that different types of magnetic resonance venography (MRV) have advantages in diagnosing CVST. We conducted this meta-analysis to assess the accuracy of MRV in identifying CVST. We searched the Embase, PubMed, and Chinese Biomedical (CBM) databases comprehensively to retrieve eligible …

对于内科治疗下仍有持续或进展症状的cvst患者或有血栓扩大迹象的cvst患者，建议早期随访进行ctv或mrv检查。 (Ⅰ类，C级证据) 对于临床表现为CVST复发症状，并既往有明确CVST病史的患者，建议复查CTV或MRV。

2022年8月15日 · 在临床中遇到的cvst患者绝大部分是急性后期、亚急性期或慢性期，mri表现较为典型，极易诊断。 而在急性早期为长T1、短T2信号，极易漏诊。 以下几点有助于脑静脉窦血栓形成的MRI诊断：(1)多方位扫描显示正常静脉窦血流流空信号消失，而呈中等T1或短T1信号。

2019年4月17日 · The combination of CT/CT venography (CTV) or MRI/MR venography (MRV) is highly accurate for the evaluation of CVST. MRI and MRV have the advantage of better evaluating parenchymal lesions, not exposing the patient to radiation and most of the times not requiring the administration of contrast agent, but require patient collaboration due to the ...
