成人冠状动脉造影中动脉起源异常分析

目的 利用较大样本冠状动脉造影资料分析国人先天性冠状动脉开口起源异常的检出频度。方法 回顾性研究分析1988年8月至2003年12月阜外医院22 636例成年人冠状动脉造影资料,将检出的先天性冠状动脉开口起源异常进行总结和分类,并与国内外文献进行比较。结果22 636例冠状动脉造影中检出冠状动脉开口起源异常234例,总检出率为1.03％。其中右冠状动脉起源异常138例(58.97％),是涉及起源异常最多见的冠状动脉;左冠状动脉起源异常89例(38.03％);左、右冠状动脉开口起源均异常1例(O.43％);单一冠状动脉6例(2.57％)。22 636例冠状动脉造影中冠状动脉分布优势类型:右优势型19 940例(88.09％),均衡型1500例(6.63%),左优势型1196例(5.28％)。结论 这是迄今为止收入样本量最大的有关国人冠状动脉起源异常的造影资料分析。其先天性冠状动脉起源异常检出率与国外文献报道相符,但类型特点有所不同。

Analyses of anomalies origin of coronary artery in 22 636 adult patients undergoing coronary arteriography

Objective To investigate the patterns of anomalous origin of coronary artery and frequency of occurrence in Chinese adults undergoing coronary arteriography. Methods A retrospective review on the angiographic data of department of interventional therapy of Fu Wai hospital, analysed the anomalous origin of coronary antery among 22 636 Chinese adult patients who underwent coronary arteriography from August 1988 to December 2003, and contrasted the patterns and the frequency of occurrence to the existed studies. Results Among 22 636 patients, 234 cases were found to have anomalous origin of the coronary artery ( 1. 03% detection rate ). Detection rate of anomalous origin of the right coronary artery(RCA) , the left coronary artery(LCA) , both RCA and LCA was 58. 97% , 38. 03% , 0.43% , and single coronary artery was 2. 57% . Of the 22 636 patients, 88. 09 per cent was found to be the right dominance, 6. 63 per cent was the mixed dominance, and 5. 28 per cent was the left dominance type. Conclusion This is a study on anomalous origin of coronary artery in arteriographic adults, which has the largest patient cohorts reported from China up to now. All the anomalies were discovered as incidental findings during coronary arteriography. The total detection rate of this study is similar to that of the existed ones, while some of the character of the anomalous origin of coronary artery were different.
