Carotid stenosis is a major risk factor for ischemic stroke. However, the effect of carotid stenosis on the site of stroke is still under investigation.
This study aimed to elucidate how the presence of carotid stenosis influenced the pattern of stroke and also how it interacted with other risk factors for stroke.
Thirty-eight patients with ischemic stroke were included in this study and were investigated with carotid artery Doppler and magnetic resonance angiography for carotid stenosis and intracranial stenosis in the circle of Willis, respectively. Other known risk factors of stroke were also studied in and compared between the subgroups with and without carotid stenosis.
In patients without carotid stenosis, anterior cerebral artery was the commonest site of stenosis. In patients with carotid stenosis, middle cerebral artery was the commonest site of stenosis. Overall, middle cerebral artery was the commonest territory of stroke. Patients with hypertension, diabetes and history of smoking had preferential stenosis of the anterior cerebral artery.
颈动脉狭窄是缺血性卒中的主要危险因素。然而，颈动脉狭窄对卒中部位的影响仍在研究中。
本研究旨在阐明颈动脉狭窄的存在如何影响卒中模式，以及它如何与其他卒中危险因素相互作用。
本研究纳入了38例缺血性卒中患者，分别采用颈动脉多普勒和磁共振血管造影对颈动脉狭窄和 Willis 环内的颅内狭窄进行了研究。还对有和没有颈动脉狭窄的亚组中的其他已知卒中危险因素进行了研究和比较。
在没有颈动脉狭窄的患者中，大脑前动脉是最常见的狭窄部位。在有颈动脉狭窄的患者中，大脑中动脉是最常见的狭窄部位。总体而言，大脑中动脉是最常见的卒中区域。患有高血压、糖尿病和有吸烟史的患者大脑前动脉有优先狭窄。
