摘要
目的分析主动脉CT作为冠状动脉旁路移植(coronary artery bypass grafting,CABG)术前常规检查的必要性及应用价值。方法回顾分析2012年11月至2014年9月在本院行单纯CABG的患者。共有794例CABG患者在手术前进行了全主动脉64排螺旋CT检查,其中男604例,女190例,平均年龄(63.85±8.41)岁。结果在所有患者中,425例患者(53.5%)仅有轻度动脉粥样硬化改变,无主要分支血管狭窄或闭塞,369例患者(46.5%)合并不同程度的分支血管狭窄或闭塞,其中91例患者(11.5%)有单侧或双侧颈动脉狭窄大于50%或闭塞,117例患者(14.7%)发现腹主动脉严重钙化伴主要分支血管狭窄大于50%或闭塞(腹腔干动脉、肠系膜上动脉等),33例患者(4.2%)发现升主动脉病变,包括钙化或扩张直径超过45mm,121例患者(15.2%)发现单侧或双侧髂动脉狭窄大于50%或闭塞,有40例患者(5%)发现主动脉全程弥漫粥样硬化改变,伴多个分支狭窄或闭塞,100例患者(12.6%)发现单侧或双侧肾动脉狭窄大于50%或闭塞。结论主动脉钙化在CABG患者中非常普遍,随着年龄增加,各分支血管病变发生率明显增加,在临床上应该引起足够的重视,64排螺旋CT检查作为一项无创、经济、准确的检查方法,能对主动脉病变进行准确定位、分型、精确测量、定量分析所属分支血管及脏器有无受累,所以对于高龄CABG患者,术前建议常规行主动脉CT检查,以便减少围术期动脉粥样硬化相关并发症的发生。
Abstract
Objective To assess the clinical value of 64 slice spiral CT for coronary artery bypass surgery.MethodWe retrospectively reviewed data collected from 794 patients who underwent isolated CABG at Fuwai Hospital from November 2012 to September 2014. Of these patients, 604 patients was male and 190 patients was female, the mean age was (63.85±8.41). Calcification of aorta was assessed by 64 slice spiral CT before operation.ResultThere were 425 patients (53.5%) without calcification of aorta, 91 patients (11.5%) with unilateral or bilateral carotid stenosis, 117 patients(14.7%) with descending thoracic aortic calcification, 33 patients (4.2%)with ascending thoracic aortic calcification and 100 patients(12.6%)with renal artery stenosis.Conclusion Calcification of thoracic aorta is very common in old people. 64 slice spiral CT is anon-invasive, safe and effective method for evaluating calcification of aorta for patients undergoing coronary artery bypass surgery.
