颈内动脉发育不全

定义 英文原文（暂无中文）

A rare vascular anomaly characterized by agenesis (complete absence of the carotid canal), aplasia (a remnant of the artery remains) or hypoplastic (incomplete embryonic development) of the internal carotid artery, which can be unilateral or bilateral. Children with the condition are mostly asymptomatic due to the presence of collateral circulation. With increasing age, the risk of cerebrovascular events increases. Patients may present with headache, seizures, or transient ischemic attacks. Cerebral aneurysms may form in the context of the condition.
