颈部血管彩色超声及头颅CT血管造影对缺血性脑血管病的诊断价值

目的:评价颈部血管彩色超声及头颅CT血管造影(CTA)对缺血性脑血管病的诊断价值。方法:选取符合缺血性脑血管病的诊断标准的患者42例,这些患者都进行过头颅CTA及颈部血管超声检查。详细记录颅内血管病变及颈动脉粥样硬化斑块部位及斑块性质情况。结果:在42例缺血性脑血管病患者中,头颅CTA共检测出颅内动脉粥样硬化13例、动脉狭窄27例、动脉闭塞14例。颈动脉粥样硬化斑块好发部位以颈动脉膨大处多见、并多为两侧同时受累,其次为颈总动脉、颈内动脉起始处和颈内动脉。结论:CTA对缺血性脑血管病患者的颅内病变血管的阳性检出率较高,颈部血管彩超可以显示缺血性脑血管病患者的颈部血管斑块形成的部位、斑块性质、管腔狭窄情况。2种检查联合应用可以互补不足,可以很好地指导治疗及评价预后。

Research on the Diagnostic Values of Carotid Duple a Ultrasound and Brain CTA in Patients with Ischemic Cerebrovascular Disease

Objective:To evaluate the diagnostic values of carotid duples ultrasound and brain CTA in patients with ischemic cerebralvascular disease. Methods:Select accord with ischemic cerebrovascular disease diagnosis standard of 42 patients with patients, these patients of ischemic cerebral vascular diseases were examined by brain CTA and Neck vascular color doppler ultrasound. Detailed records Intracranial vascular lesions and the location and nature of carotid atherosclerotic plaques. Results:In 42 patients with ischemic cerebrovascular disease, 13 cases with intracranial atherosclerosis and 27 cases with artery stenosis and 14 cases with artery occlusion were detected by brain CTA. Carotid atherosclerotic plaques is the most common near the swollen with carotid artery, then common carotid artery, internal carotid artery initial segment and internal carotid artery. Conclusions: The higher of positive rate of CTA to diagnosis intracranial vascular lesions in patients with ischemic cerebral vascular diseases, Neck vascular color doppler ultrasound can display the location and nature of plaques、stenosis of blood vessel among patients who subjected ischemic cerebral vascular disease . The combined application can complement each other, and hence guide the evaluation of treatment and prognosis.
