Abstract:
Objective To study the location of coronary chronic total occlusion and the correlatin between coronary chronic total occlusion and coronary collateral. Methods SPSS was used to analyze the general clinical and coronary angiographic data of 113 patients with coronary bypass surgery performed. Results There were 61 patients with coronary chronic total occlusion. 71 sites of coronary chronic total occlusions were observed by coronary angiography, of which, one was located in left main coronary artery (0 9%), 17 in proximal left anterior descending artery (15 0%) , 9 in middle left anterior descending artery (8 0%), 3 in distal left anterior descending artery (2 7%), 5 in proximal left circumflex artery (4 4%), 6 in middle left circumflex artery (5 3%), 3 in distal left circumflex artery (2 7%), 9 in proximal right coronary artery (8 0% ), 10 in middle right coronary artery (8 8% ) and 8 in distal right coronary artery (7 1% ). There were 72 patients with coronary collateral. The coefficient of correlation between collateral and coronary chronic total occlusion was 0 707 (P=0 000 ).Conclusions Coronary chronic total occlusion is frequently located in proximal, middle left anterior descending artery and right coronary artery. There is significantly positive correlation between collateral and coronary chronic total occlusion.
