Dissecting aneurysms of the intracranial arteries display vascular pathological features that appear sporadically, generally affecting young adults. The clinical features of this condition may involve both ischemic episodes and hemorrhages. Posterior circulation is affected less than the rest of the intracranial arteries, and it is extremely rare to find the posterior cerebral arteries only affected. Mortality is high in patients where the lesion is located in the posterior intracranial circulation, although dissecting aneurysms limited to the posterior cerebral arteries may, to a certain extent, be benign. We report the case of a young woman with ischemia in the territory of the posterior cerebral artery that occurred subsequent to a dissecting aneurysm that resolved spontaneously to a complete remission, both clinically and as demonstrated by angiography. A review of the literature is made, analyzing the pathogenic, clinical, angiographic, and therapeutic characteristics of such lesions.
颅内动脉夹层动脉瘤呈现出偶发的血管病理特征,通常影响年轻人。这种疾病的临床特征可能包括缺血性发作和出血。后循环受累程度低于颅内其他动脉,仅发现大脑后动脉受累极为罕见。病变位于颅内后循环的患者死亡率很高,尽管局限于大脑后动脉的夹层动脉瘤在一定程度上可能是良性的。我们报告了一例年轻女性病例,该患者在大脑后动脉供血区出现缺血,继发于夹层动脉瘤,该夹层动脉瘤在临床及血管造影显示下均自发完全缓解。本文对相关文献进行了综述,分析了此类病变的致病、临床、血管造影及治疗特征。
