目的　确定脑静脉血栓系统形成 (CVT)的临床特征及常见病因。方法　回顾 91例CVT患者的临床及影像学资料。结果　本组男 49例 ,女 42例 ,年龄 9～ 57岁 ,平均 (32 1± 1 0 8)岁。78例 (85 71 % )行MRI检查 ,37例 (40 66 % )行磁共振血管造影 (MRA)检查 ,32例 (35 1 6 % )行数字减影血管造影术检查。临床表现为单纯高颅压型占 2 7例 (2 9 67% ) ;局灶性缺损或 (和 )癫痫型占 56例(61 54 % ) ;脑病型 3例 ,海绵窦血栓形成 5例。口服避孕药 1 2例 (1 3 1 9% )。结论　认识CVT的临床特征并及时行MRI及MRA联合检查是正确诊断CVT的关键 ;口服避孕药是CVT最常见的原因

A study on the diagnosis and etiology of cerebral venous thrombosis

Objective To determine the clinical characteristic and common etiologies of cerebral venous thrombosis(CVT) in China Methods Clinical and neuroimaging data of 91 cases of CVT were analyzed retrospectively Results 91 CVT patients(49 men,42 women), aged from 9 to 57 years, were diagnosed with MRI(78 cases, 85 71%), MRA(37 cases, 40 66%) or DSA(32 cases, 35 16%) 27 cases(29 67%) had a clinical pattern of isolated intracranial hypertension, 56 cases(61 54%) of focal deficits and/or seizures, 3 cases of subacute encephalopathy and 5 cases of cavernous sinus thrombosis Oral contraceptive was the most common cause , being found in 12 cases(13 19%) Conclusions Understanding of the clinical characteristics of CVT and using of MRI and MRA examination as early as possible is the key in CVT diagnosis Oral contraceptive is the most common etiology
