椎动脉夹层动脉瘤较少见,约占椎动脉瘤的(?),可经常规血管造影,MRI等放射学方法诊断。作者报告了1例经3次血管造影才发现的椎动脉夹层动脉瘤患者。 患者,女,59岁。因头痛入院,CT扫描为右额叶(?)密度损害灶,MRI:右额叶T_1加权低信号、T_2加(?)信号,没有明显增强。3条血管造影有肿瘤占位(?)、没有肿瘤染色。经右额行肿瘤显微切除时出现明显的脑肿胀,静脉注射甘露醇后肿胀消退。术后病情稳定,术后1天CT复查发现有基底池、环池,外侧裂池积血,脑血管造影正常。9天后出现剧烈头痛并意识障碍,CT扫描示第Ⅲ、Ⅳ脑室出血及脑积水,再次3条血管造影,发现椎动脉(V_4)梭型动脉瘤,中
Vertebral artery dissection aneurysm is rare, about vertebral aneurysms (?), Can be routine angiography, MRI and other radiological diagnosis. The authors reported 1 patient who had been diagnosed with dissecting aneurysms of the vertebral artery by 3 angiography. Patient, female, 59 years old. Due to headache admission, CT scan showed lesions of right frontal lobe (?) Density, MRI: right lower frontal T 1 weighted low signal, T 2 plus (?) Signal, no significant increase. Three angiographic tumor sites (?), No tumor staining. The right forehead tumor microtome obvious brain swelling, intravenous mannitol swelling subsided. The postoperative condition was stable. One day after the operation, CT examination revealed basal pool, perihepatic pool, lateral fissure pool hemorrhage, and normal cerebrovascular angiography. Nine days later, severe headache and disturbance of consciousness occurred. CT scan showed ventricular hemorrhage and hydrocephalus of grade III and IV. Three angiograms were performed again and found that the vertebral artery (V_4) shuttle type aneurysm
