Clinical analysis of 1018 cases of coronary artery bypass grafting / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze retrospectively 1018 patients who underwent coronary artery bypass grafting surgery (CABG) in order to summarize surgical techniques and clinical outcome.</p><p><b>METHODS</b>From 1997 through 2004, data of same surgeon for 508 patients who underwent conventional coronary artery bypass surgery on pump (CCABG) and 510 patients who underwent off-pump CABG (OPCAB) were collected and analyzed retrospectively. Eight hundred and fifty-two patients had unstable angina, 582 patients were over 60 years old (57.2%) and 784 patients had concomitant diseases including valve lesion, hypertension, diabetes, myocardial infarction, left ventricular aneurysm with septal defect, stroke, chronic obstructive pulmonary diseases, renal failure and cancer. A hundred and fifty-six patients had left main stem (LIMS) stenosis and 671 patients, triple-vessel disease.</p><p><b>RESULTS</b>Total mortality was 0.39% (4-case death) and morbidity, 1.6% (sternal dehiscence, stroke and mediastinitis). The grafts per patient with CCABG and OPCAB were 3.3 +/- 0.6 vs. 2.5 +/- 0.4. Left internal mammary artery use was 93.8% of the patients, 29 patients were implanted intra-aortic balloon pump intraoperatively. Follow-up was 4 months to 7 years.</p><p><b>CONCLUSIONS</b>Scientific surgical strategies, excellent surgical techniques and improvement of cardiac anesthesia and cardiopulmonary bypass make the mortality and morbidity decrease significantly, CABG surgery is safe and effective in patients with coronary artery disease.</p>
