The authors report a case of dolichoectasic intracranial arteries associated with an aneurysm of the abdominal aorta. The patient presented with a double hemorrhagic vascular rupture, the abdominal aortic aneurysm being operated on as an emergency, with a favorable outcome. The cerebral and aortic angiograms showed extension of the pathological process to the large caliber arteries. Microcirculatory investigations at the nail bed and conjunctiva also showed distal lesions. The vascular abnormality underlying these multiple ectasic lesions would seem to be different to that of classical arteriosclerosis. Anatomopathological studies reported in the literature describe fibrous degenerative lesions of the media differing from those observed in fibromuscular dysplasia.
作者报告了一例颅内动脉延长扩张伴腹主动脉瘤的病例。患者出现双重出血性血管破裂，腹主动脉瘤作为急症进行了手术，结果良好。脑动脉造影和主动脉造影显示病变过程延伸至大口径动脉。甲床和结膜的微循环检查也显示有远端病变。这些多处扩张性病变潜在的血管异常似乎与经典动脉硬化不同。文献报道的解剖病理学研究描述了中膜的纤维性退行性病变，与纤维肌发育不良中观察到的病变不同。
