RESEARCH ON THE CORONARY COLLATERAL CIRCULATION BY DIGITAL SUBTRACTION ANGIOGRAPHY OF PATIENTS WITH MULTI VESSEL CORONARY ARTERY DISEASE
Main Article Content
Abstract
Purpose: To determine the prevalence and the degree of coronary collaterals in patients with multi-vessel coronary artery disease. Subjects and methods: The retrospective cross-sectional description study was proceeded atCardiovascular Intervention Center, Hanoi Medical University Hospital from July 2018 to July 2019. A total of 41 patients with multi-vessel coronary artery disease were recruited to this study. Results: In this study, Coronary collateral circulation was graded Rentrop 1 in 14.6%, Rentrop 2 in 24.4% and Rentrop 3 in 4.9% of these patients. In the left anterior descending obstruction, there are 37.5% type F collateral circulation. In the circumflex artery obstruction, there are 66,7% type D collateral circulation. In the Right coronary obstruction, there are 60 % type A collateral circulation. Conclusion: The degree of collateral circulation assessed by the Rentrop score is a useful methods in the population with multi-vessel coronary artery disease, and pathways cororary collateral circulation by LeVin1974.
