Preliminary results of combined carotid endarterectomy and off-pump coronary artery bypass grafting in patients with coexistent carotid and coronary artery diseases / 中华医学杂志(英文版)

ABSTRACT

<p><b>BACKGROUND</b>Coexistent carotid and coronary artery diseases are common and patients with them remain at a high risk for perioperative stroke or myocardial infarction after coronary bypass surgery. The aim of this study was to investigate the effect of combined carotid endarterectomy (CEA) and off-pump coronary artery bypass grafting (CABG) in patients with coexistent carotid and coronary artery diseases.</p><p><b>METHODS</b>Between January 2002 and December 2007, consecutive patients with coexistent carotid and coronary artery diseases underwent one-stage unilateral CEA and off-pump CABG in Heart Institute of Nanjing First Hospital Affiliated to Nanjing Medical University. Perioperative complications were assessed and follow-up was carried out.</p><p><b>RESULTS</b>A total of 51 cases of isolated off-pump CABG and unilateral CEA, including 34 right and 17 left, were performed. The mean blocked time of carotid artery in CEA was (25.5 +/- 7.0) minutes. The mean number of distal grafts per patient was 3.30 +/- 0.45. The mean ventilation time, intensive care unit stay, and postoperative hospital stay was (11.3 +/- 5.4) hours, (2.1 +/- 0.9) days, and (12.5 +/- 6.1) days respectively. None of the patients had stroke or myocardial infarct. There was one perioperative death due to acute cardiac failure, resulting in an operative mortality of 1.96%. Follow-up was completed for 47 patients (92.16%) with a mean follow-up of (39.5 +/- 12.5) months. None of the patients manifested stroke, new angina or newly developed cardiac infarct. No late death occurred.</p><p><b>CONCLUSION</b>Combined CEA and off-pump CABG is a safe and effective procedure in selected patients with coexistent carotid and coronary artery diseases.</p>
