We report a 73-year-old woman with de novo arteriovenous malformations (AVMs) that developed in the ipsilateral parietal lobe after craniotomy and aneurysm clipping. While intracerebral AVMs are considered to be congenital lesions, there have been several reported cases of acquired AVM arising after ischemic or traumatic episodes. We summarize previously reported cases of such acquired 'de novo' AVMs with a discussion of some pathophysiological responses or factors suggested to promote their development.
我们报告了一名73岁女性，其在开颅手术和动脉瘤夹闭术后，同侧顶叶出现了新发的动静脉畸形（AVM）。虽然脑内AVM被认为是先天性病变，但已有数例报道称，在缺血或创伤事件后会出现后天性AVM。我们总结了先前报道的此类后天性“新发”AVM病例，并讨论了一些被认为促进其发展的病理生理反应或因素。
