Agenesis of the internal carotid artery (aICA) is a rare congenital vascular condition that can affect one or both sides of the patient. Most patients remain asymptomatic, but ischemic/hemorrhagic stroke, intracranial aneurysm, and other neurologic findings can occur. CT scan can demonstrate the absence of the bony carotid canal and helps to differentiate a complete aICA from aplasia or hypoplasia. The association of aICA and aqueductal stenosis (AS) has never been reported in the literature. We report the case of a 9-year-old with agenesis of the right ICA associated with AS and hydrocephalus, which was treated successfully with an endoscopic third ventriculostomy (ETV). We review the literature looking for the association of the clinical findings and the evolution of the patient.
颈内动脉发育不全（aICA）是一种罕见的先天性血管疾病，可影响单侧或双侧患者。大多数患者无症状，但可出现缺血性/出血性中风、颅内动脉瘤和其他神经系统表现。CT 扫描可显示骨颈动脉管缺失，并有助于区分完全性 aICA 与发育不全或发育不良。ICA 发育不全与导水管狭窄（AS）的关联在文献中从未有过报道。我们报告了一例 9 岁儿童右侧 ICA 发育不全合并 AS 和脑积水，成功接受了内镜第三脑室造瘘术（ETV）治疗。我们回顾了文献，寻找临床发现和患者病情演变的关联。
