Study On The Application Of Bilateral Coronary Angiography In Chronic Coronary Total Occlusion Percutaneous Coronary Intervention

Objective:To investigate the safety and feasibility of the application on bilateral coronary angiography in chronic coronary total occlusion percutaneous coronary interventionMethods:96 routine coronary angiography examination revealed a chronic total occlusion lesions in the patient study, based on whether the lesion revascularization use of the contralateral coronary angiography interventional therapy patients were divided into two groups. One group of 53 cases of coronary angiography unilateral, bilateral group of 43 cases of coronary angiography. All the patients before and after surgery were subject to the same medication. Two groups were observed in patients with sex, age, with or without smoking history, with or without diabetes, hypertension, hyperlipidemia, and whether or myocardial infarction, stable angina, unstable angina, silent myocardial ischemia history. Compared two groups of patients with coronary artery disease location, disease rates, and the opening of vascular surgery and postoperative complications. All statistics used SPSS13.0 measurement information to groups t test, X2 test was used for count data to statistical analysis, P<0.05 as statistically significant.Results:In this study of 96 patients with chronic occlusion of patients, bilateral coronary angiography group than in the unilateral group of interventional treatment of coronary angiography a high success rate, P<0.05. Bilateral intraoperative angiography group was lower than the incidence of coronary dissection unilateral imaging group, while the incidence of contrast-induced nephropathy than unilateral imaging group, P<0.05. Two groups of postoperative restenosis, no-reflow, vagal reflex, local bleeding puncture site hematoma, pseudoaneurysm was no significant difference, P> 0.05. The two groups in age, sex, smoking history, hypertension, hyperlipidemia, diabetes, history, the history of myocardial infarction, stable angina, unstable angina, silent myocardial ischemia in history, in the event of disease the site was no significant difference (P> 0.05).Conclusion:Bilateral coronary angiography coronary intervention in the course of treatment is safe and feasible. Coronary angiography in patients with bilateral involvement of the treatment success rate of coronary angiography is superior to unilateral group. Bilateral coronary angiography group involved in the course of treatment the incidence of coronary artery dissection below the unilateral coronary angiography group, the incidence of contrast-induced nephropathy is higher than unilateral coronary angiography group(After long-term follow-up found a positive and timely symptomatic treatment, contrast agent nephropathy were good, some of the clinical syndrome can be spontaneous remission, without acute tubular necrosis, kidney failure and other complications). Two groups of patients with restenosis, no-reflow, vagal reflex, local bleeding puncture site hematoma, pseudoaneurysm was no significant difference.
