摘　　要：目的探讨颅内静脉窦血栓患者30例的临床特点及影像学表现。方法回顾性分析30例诊断为颅内窦静脉血栓患者的临床特点及影像学表现。结果本组30例患者中,31-50岁CVST发病率最高;病因以妊娠相关因素最为常见,占23.33%;30例均行头颅CT平扫,显示16例存在异常,其中3例出现弥漫性脑水肿,存在空三角征;5例脑实质低密度影;2例病变静脉窦内出现高密度影;27例行MRI扫描结果显示,22例脑内信号异常,其中8例为单侧病灶,14例为双侧病灶。26例MRV检查显示存在不同程度的窦静脉病变,主要表现为受累窦静脉不显影或显影不清。DSA检查结果显示存在不同程度的窦静脉堵塞。结论 CVST的病因较为复杂,临床症状表现不一,疑似CVST患者应及时行CT、MRI及MRV等影像学检查,进行疾病确诊,并早期给予个性化治疗,能够改善疾病预后。Objective To investigate the clinical features and imaging findings of 30 cases of patients with intracranial venous sinus thrombosis, and to improve the understanding of the disease. Methods The clinical features and imaging findings of 30 patients with intracranial venous sinus thrombosis were retrospectively analyzed. Results Among the 30 patients, the morbidity of CVST in 31-50 year-old patients was the highest,. The 30 cases were given CT scan, which showed that there was abnormity in 16 cases, including 3 cases of diffuse brain edema, with empty triangle sign, 5 cases of brain parenchyma low- density shadow; 2 cases with high-density shadow in the diseased venous sinus. MRI scan was performed in 27 cases, which showed that there were 22 cases of abnormal brain signal, including 8 cases of unilateral lesions and 14 cases of bilateral lesions. The main features were cerebral infarction and cerebral edema. 26 cases of MRV examination showed that there were different degrees of sinus venous diseases and the main performance was affected sinus venous not developing or not clearly developing. DSA examination showed that there were different degrees of sinus venous congestion. Conclusion The cause of CVST is complex and the clinical symptoms are different. Patients with suspected CVST should receive CT, MRI, MRV and other imaging examinations to diagnose the disease, and to receive early individualized treatment, which can improve the prognosis of the disease.
