颈内动脉发育不良是一种罕见的先天性病变,有时难以与获得性血管病变如动脉夹层或血管炎引起的血管狭窄相鉴别。由于颈内动脉发育下良常伴有颈动脉管发育不良,因此测量颈动脉管的大小可以作为诊断颈内动脉发育不良的有用指征。本研究的目的是要确定颅底CT扫描是不是一个诊断颈动脉管发育不良的可靠方法。 对4例血管造影确诊有颈内动脉发育不良(1例为双侧)的患者和30例正常人做平行于眶耳线的颅底CT扫描,层厚1.2～2.5mm,在蝶骨的颈动脉鞘层面测量颈动脉管的大小。4例患者的临床表现为头痛、恶
Carotid artery hypoplasia is a rare congenital disease that is sometimes difficult to distinguish from acquired vascular lesions such as arterial dissection or vasculitis caused by vascular stenosis. Due to the development of internal carotid artery often accompanied by poor development of carotid artery, so measuring the size of the carotid artery can be used as a diagnosis of poor indications of carotid artery dysplasia. The purpose of this study was to determine if a skull base CT scan is a reliable method of diagnosing carotid vascular dysplasia. Four patients with angiographically diagnosed carotid artery dysplasia (one case of bilateral) and 30 normal subjects were performed skull base CT scan parallel to the orbital ear. The thickness of the skull base was 1.2-2.5 mm. Arterial sheath surface to measure the size of the carotid artery. 4 patients with clinical manifestations of headache, evil
