尽管对脑血管畸形的组织学特征已有报道 ,但其透射电镜的系统研究尚未见报道。本文通过对 3例脑动静脉畸形(ＡＶＭ )和 3例海绵状血管畸形 (ＣＭ )的手术标本进行透射电镜观察并对照因难治性癫而行颞叶切除所获得的正常组织 ,从血管壁内皮下层、内皮细胞和细胞连接等方面初步 Although the histological characteristics of cerebrovascular malformations have been reported, but its transmission electron microscopy system has not been reported. In this paper, 3 cases of cerebral arteriovenous malformations (AVM) and 3 cases of cavernous vascular malformations (CM) of the surgical specimens were observed by transmission electron microscopy and control due to refractory epilepsy and temporal lobe resection of the normal tissue obtained from the blood vessels Wall endothelial sub-layer, endothelial cells and cell connections and other aspects of the initial
