摘　　要：目的提高对静脉性脑梗死的临床及影像学表现的认识。方法回顾性分析21例静脉性脑梗死患者的临床及影像学表现。结果患者存在颅内静脉血栓高危因素的14例,主要为口服避孕药、中耳乳突炎、产褥期等;临床表现为头疼、呕吐、癫痫、肢体功能障碍、失语、视物模糊等;脑实质病变位于大脑皮层下及皮层区19例(双侧6例、累及小脑2例),丘脑2例,17例为出血性梗死;15例血栓累及多个静脉窦。结论静脉性脑梗死临床表现缺乏特异性,当发现非常规分布的脑梗死、出血,结合血栓高危因素等应想到静脉性脑梗死可能,及时的MRV/CTV检查有助于诊断。Objective To explore the clinical and radiological features of cerebral venous infract. Methods Twenty-one ea- ses with cerebral venous infract were collected and the corresponding clinical and imaging findings were retrospective analyzed. Results Intracranial venous thrombosis risk factors were found in fourteen cases, mainly for the oral contraceptives, otitis media, puerperal, etc; They presented with headache, vomiting, seizures, limb dysfunction, aphasia, blurred vision, etc. Parenchymal lesions located in the cerebral cortex and subcorfical in nineteen cases （ bilateral lesions in six cases, involved the cerebellum in 2 cases）, located in bilateral thalamus in two eases. Hemorrhagic infarctions were found in seventeen cases. Multiple sinus thrombus were involved in fifteen cases. ConcLusion The clinical manifestations of cerebral venous infarction lack of specificity. The venous infarction should be taken into consideration when the abnormal distribution of cerebral infarction/ hemorrhage com- bined with the high-risk factors of thrombosis were found and MRV/CTV is helpful for diagnosis.
