A 60-year-old female and a 40-year-old male underwent surgical revascularization for moyamoya disease and suffered small infarction in the ipsilateral frontal lobe 3 or 4 days postoperatively. Neuroimaging suggested that the bypass flow had caused rapid progression of occlusive changes in the carotid forks, a diminishing of moyamoya vessels, and flow reduction in the anterior cerebral artery ipsilateral to surgery, leading to critical ischemia in the frontal lobe. Surgical revascularization improves the outcome of patients with moyamoya disease, but postoperative management such as hydration is important to avoid ischemic complications due to frontal lobe infarction.
一名60岁女性和一名40岁男性因烟雾病接受了外科血管重建术，术后3或4天在同侧额叶发生了小梗死。神经影像学检查表明，搭桥血流导致颈动脉分叉处闭塞性改变迅速进展、烟雾状血管减少以及手术同侧大脑前动脉血流减少，从而导致额叶严重缺血。外科血管重建术可改善烟雾病患者的预后，但术后管理（如水合作用）对于避免因额叶梗死引起的缺血性并发症很重要。
