探讨脑静脉窦血栓形成的临床与影像学特点

Explore Clinical and Imaging Features of Cerebral Venous Sinus Thrombosis

目的探讨脑静脉窦血栓形成的临床与影像学特点。方法回顾分析我院2014年3月~2015年3月收治的30例脑静脉窦血栓患者的临床资料。结果 30例患者中23例患者为急性起病,占76.67%;5例患者为亚急性起病,占16.67%;2例患者为慢性起病,占6.67%。临床特点：头痛26例,占86.67%;意识障碍22例,占73.33%;头晕8例,占26.67%,运动障碍4例,占13.33%。影像学检查特点：头颅CT检查脑梗死7例,占23.33%,平扫示条带征13例,占43.33%;经头颅MRI平扫示实三角征为16例,占53.33%;MRI＋磁共振静脉血管成像（MRV）显示脑静脉窦异常28例（93.33%）;DSA显示脑静脉窦异常26例（86.67%）。结论脑静脉窦血栓以头痛等颅高压症状以及意识与认知功能障碍为主要临床表现,神经影像学检查中CT的诊断率较低,MRI＋磁共振静脉成像（MRV）及DSA的确诊率高,临床上应注意各类诊断仪器的共同使用,提高临床诊断率。

Objective To explore Clinical and imaging features of cerebral venous sinus thrombosis. Methods Retrospective analysis of our hospital in March 2014 ~ March 2015 patients clinical data of 30 cases of cerebral venous sinus thrombosis. Results 30 cases in 23 patients with acute onset, accounted for 76.67%;5 cases of subacute onset, accounting for 16.67%;2 patients of chronic onset, accounting for 6.67%.Clinical features ： a headache 26 cases（86.67%）,Disturbance of consciousness, 22 cases（73.33%）,Dizziness, 8 cases, accounting for 26.67%, dyskinesia 4 cases, accounting for 13.33%.Imaging characteristics ： skull CT examination of brain infarction in 7 cases, accounted for 23.33%, flat sweep every stripe in 13 cases, accounting for 43.33%;After cranial magnetic resonance imaging（MRI） scan in real triangle sign for 16 cases, accounting for 53.33%;MRI ＋ vein imaging（MRV） showed abnormal cerebral venous sinus 28 cases（93.33%）.DSA showed abnormal cerebral venous sinus 26 cases（86.67%）.Conclusion Cerebral venous sinus thrombosis in cranial pressure symptoms such as headache and consciousness and cognitive dysfunction as the main clinical manifestations, neuroimaging examination of CT diagnosis rate is low, MRI ＋ vein imaging（MRV） and DSA diagnosis rate is high, should be paid attention to all kinds of clinical diagnostic instruments in common use, improve the clinical diagnostic rate.
