烟雾病(Moyamoya)累及颈内动脉末端和大脑中动脉、前动脉起始部狭窄或闭塞,并形成侧支循环已有文献报道。近年又发现烟雾病的特征性病变亦见于颈外动脉系统的颞浅动脉和脑膜中动脉,并发现颈内动脉颈段狭窄。为了进一步证实烟雾病不单纯是一种脑血管病,我们对近期收治的一例烟雾病患者施行了数字减影(DSA)下肢动脉造影和枕动脉的超微病理学观察,报告如下。
Moyamoya affects the end of the internal carotid artery and the middle cerebral artery. The stenosis or occlusion of the anterior part of the anterior artery and the formation of collateral circulation have been reported in the literature. In recent years, found that the characteristic lesions of moyamoya disease also found in the supercortical artery and middle meningeal artery of the external carotid artery, and found that the neck segment of the internal carotid artery stenosis. In order to further confirm that moyamoya disease is not merely a cerebrovascular disease, we performed digital ultrasonography (DSA) of the lower extremity arteriography and occipital artery in one recently treated moyamoya disease, and the results are as follows.
