目的 研究冠状动脉慢性完全阻塞性病变的分布特征及其与侧支循环间的相关关系。方法 用SPSS统计软件分析113例冠状动脉旁路术患者的临床基线资料和冠状动脉造影资料。结果 慢性完全阻塞性病变 61例 ( 71处 ) ,分布于 :左主干 1例( 0 9%) ;前降支近段 17例 ( 15 0 %)、中段 9例 ( 8 0 %)、远段 3例 ( 2 7%) ;回旋支近段 5例 ( 4 4%)、中段 6例 ( 5 3 %)、远段 3例( 2 7%) ;右冠状动脉近段 9例 ( 8 0 %)、中段 10例 ( 8 8%)、远段 8例 ( 7 1%)。侧支循环 72例 ( 63 7%) ,慢性完全阻塞性病变与侧支循环间的直线相关系数r=0 70 7(P =0 0 0 0 )。结论 冠状动脉慢性完全阻塞性病变多见于前降支、右冠状动脉的近、中段 ,与侧支循环间有高度正相关性
Objective To study the distribution of chronic obstructive coronary disease and its relationship with collateral circulation. Methods The clinical baseline data and coronary angiography data of 113 patients undergoing coronary artery bypass surgery were analyzed by SPSS statistical software. Results There were 61 cases of chronic obstructive lesions (71 sites) in 1 case (0 9%) in the left main trunk, 17 cases (15 0%) in the proximal anterior descending artery, 9 cases (80%) in the middle segment, 3 cases (27%) in 3 cases (27%), 5 cases (4 4%) in the proximal circumflex artery, 6 cases (53% ), 10 cases (8 8%) in the middle and 8 cases (7 1%) in the distal. Collateral circulation in 72 patients (63.7%), chronic obstructive lesions and collateral circulation linear correlation coefficient r = 0 707 (P = 0 0 0 0). Conclusion The chronic total occlusion of coronary artery is more common in the anterior descending branch and the proximal and middle coronary arteries with a high degree of positive correlation with collateral circulation
