ABSTRACT
Objective To explore clinical characteristics of chronic total occlusion(CTO) in population with routine coronary angiography,and to cumulate therapeutic experience.Methods Retrospective analysis was performed on clinical data of 57 cases with CTO selected from 825 patients undergone coronary angiography.Results Among 57 cases,the percentage of male,myocaridial infarction,diabetes mellitus,hyperlipidermia and left ventricular dysfunction was 73.7%,84.2%,22.8%,73.7% and 22.8%,respectively.The types of lesions included single branch(n=11),double branches(n=29) and three branches(n=17).Of 70 branches lesion vessels,44 were TIMI 0 of blood flow classification and 26 were TIMI1.The position of lesions occurred at left anterior descending branch(n=32),left circumflex branch(n=16),right coronary artery(n=22).The occlusion time was less than three months(n=41) and more than three months(n=29).The lengths of lesion was divided into less than 20 mm(n=43) and more than 20 mm(n=27).The shapes of terminal lesion looked like rat-tail(n=42) and blaze knife-edge(n=28).The coronary stents were performed at 57 lesions among 70 branches and the successful rate of operation was 82.9%.Conclusions Timely coronary angiography and selecting suitable treatment on different kinds of lesions for male patients with myocardial infraction,especially complicated with diabetes mellitus,might play important roles in prevention of CTO and in improvement of the successful rate of percutanous coronary intervention for the complex lesion.
