Moyamoya disease is a well described phenomenon. This pattern of collateralization associated with isolated middle cerebral artery stenosis and the natural history of this entity have not been well described.
Cerebral angiograms and CT angiograms performed between August 2004 and August of 2006 demonstrating moyamoya collateralization were retrospectively reviewed. All cases of middle cerebral artery stenosis associated with a rete pattern of collateralization were included in this series. Demographic, clinical, and angiographic data were obtained.
There were three cases of middle cerebral artery stenosis associated with a moyamoya pattern of collateralization. The average age of the patients was 36-years old, 2 were male, and all were Caucasian. All patients presented with ischemic symptoms. The average degree of stenosis was 91%. No stenosis was seen in the supraclinoid internal carotid arteries or elsewhere in the intracranial vasculature.
We describe an unusual pattern of anastomosis associated with isolated severe middle cerebral artery stenosis or occlusion in Caucasians.
烟雾病是一种已被充分描述的现象。这种与孤立性大脑中动脉狭窄相关的侧支循环模式以及该疾病实体的自然史尚未得到充分描述。
回顾性分析2004年8月至2006年8月期间进行的显示烟雾病侧支循环的脑血管造影和CT血管造影。本系列纳入所有伴有网状侧支循环模式的大脑中动脉狭窄病例。获取人口统计学、临床和血管造影数据。
有3例大脑中动脉狭窄伴有烟雾病侧支循环模式。患者的平均年龄为36岁，2例为男性，均为白种人。所有患者均表现出缺血症状。平均狭窄程度为91%。在床突上段颈内动脉或颅内血管系统的其他部位未发现狭窄。
我们描述了一种在白种人中与孤立性严重大脑中动脉狭窄或闭塞相关的不寻常吻合模式。
