【摘要】 目的探讨颅内静脉窦血栓形成(CVST)的临床表现及影像学改变。方法回顾性分析46例CVST患者的发病年龄、临床表现及影像学改变。结果CVST发病年龄多为20-45岁,常发生于围产期妇女,多数为急性或亚急性起病,临床症状以头痛、癫痫发作及肢体瘫痪为主;多伴有脑脊液压力升高;核磁共振成像静脉造影(MRV)及螺旋CT静脉成像(CTV)均可发现静脉窦不同程度的静脉闭塞、回流障碍。如能及时确诊并干预,预后较好。结论对于急性或亚急性起病的以颅内高压为突出表现,而无明显中枢感染迹象的中青年患者,尤其是围产期或长期口服避孕药的育龄女性,应考虑CVST的可能。CTV和MRV的确诊率高,安全无创,检查方便、快捷,是目前诊断CVST的首选方法。更多还原

【Abstract】 Objective To investigate the clinical characteristics and image manifestations in patients with cerebral venous sinus thrombosis(CVST).Methods The age,clinical manifestation and image feature of 46 cases with CVST were reviewd retrospectively.Results The CVST happened mostly at 20~45 years old.The main clinical features of CVST were headache,seizures,paralysis,with most cases accompanied with high cerebrospinal fluid pressure.The brain CTV and MRV showed that there existed venous occlusions and backflow disability in cerebral venous sinu.The prognosis was better if patients were aprroached and treated early.Conclusion The young patients who suffered from higher cerebrospinal fluid pressure is probably considered as CVST.The brain CTV and MRV is the first choice in diagnosis of CVST.更多还原
