【摘要】 目的评价血管超声技术应用于冠状动脉搭桥术(CABG)前的临床价值及意义。方法随机抽取拟行CABG的住院患者共104例,年龄(68.9±6.09)岁,于CABG前1周之内进行颈动脉超声检查,判断颈动脉狭窄程度,对颈动脉超声提示重度狭窄和/或闭塞的患者进行颈动脉造影检查并依据检查结果进行干预治疗。结果颈动脉重度狭窄和/或闭塞患者超声和造影检查结果具有很好的相关性(相关系数r=0.92,P<0.001)。对颈动脉超声和造影均显示重度狭窄和/或闭塞的10例患者在CABG前进行了颈动脉内膜剥脱术(CEA)或颈动脉支架置入术(CAS),这些患者在CABG围术期无1例脑血管并发症发生。结论应用血管超声技术可准确检测颈动脉狭窄程度,其结果与颈动脉造影具有很好的相关性,依据颈动脉超声及造影结果,对严重狭窄和/或闭塞的颈动脉进行介入治疗或手术治疗可明显降低CABG围术期脑卒中的发生率。更多还原

【Abstract】 Objective To evaluate the clinical significance of the carotid stenosis assessed by vascular ultrasound before undergoing coronary artery bypass graft.Methods A total of 104 patients (aged 68.9±6.09 years) with coronary heart disease were scanned carotid arteries before CABG.Those patients whose carotid stenosis were severe and/or total occlusion according to carotid ultrasound were examined carotid angiography.Results There was a strong correlation between carotid ultrasound and angiography in the patients with severe carotid stenosis and/or total occlusion (r=0.92,P<0.001).There was none of cerebral complication in the 10 patients with severe carotid stenosis and/or total occlusion in the CABG perioperation period after undergoing carotid endarterectomy(CEA) or carotid artery stenting(CAS).Conclusions The results from carotid ultrasound were accurate and correlated strongly with that from carotid angiography.Undergoing CEA or CAS in those patients with severe carotid stenosis and/or total occlusion was helpful for reducing the morbidity of cerebral complication accompanying with CABG.更多还原
