颅内静脉窦和脑静脉血栓形成的临床和影像学诊断探讨

Clinical and imaging diagnosis of intracranial venous sinus and cerebral venous thrombosis

目的探讨诊断颅内静脉窦和脑静脉血栓形成的方法。方法对 6例颅内静脉窦和脑静脉血栓形成的临床及影像学资料进行分析。结果患者多表现颅内高压征象 ,伴有全脑症状或局灶神经功能异常。头颅MRI及磁共振静脉成像 (MRV)诊断颅内静脉窦和脑静脉血栓形成有肯定的价值 ,而血管数字减影 (DSA)是诊断该病的最可靠手段。结论根据临床表现及影像学检查可确诊颅内静脉窦和脑静脉血栓形成。

ObjectiveTo study how to diagnose thrombosis of intracranial venous sinus and cerebral venous thrombosis(CVT). Methods6 cases with intracranial venous sinus and CVT were analysed by clinical features and imaging signs. ResultsMost patients had symptoms and signs of intracranial hypertension. Some patients manifested symptoms of whole brain or focal neurological deficits. Magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) play important roles for the diagnosis of intracranial venous sinus and CVT, however, digital subtraction angiography (DSA) is one of the most reliable method for early diagnosis of the above diseases.Conclusions According to clinical features and imaging signs, intracranial venous sinus and CVT could be diagnosed accurately .
