Total Arterial Myocardial Revascularization with Right Gastroepiploic Artery and Bilateral Internal Thoracic Artery. An Analysis of Nine Years Experience

摘要

Introduction: We present our experience with the use of arterial conduits in order to guarantee a complete arterial myocardial revascularization. Material and Methods: From April 1994 to October 2002,169 patients (160 male, mean age 55.9 +- 7.5) underwent CABG with exclusive use of bilateral internal thoracic artery (BITA) and the right gastroepiploic artery (rGEA): Left ventricular ejection fraction ranged from 20 to 68% (mean 55.9 +- 6.8 %). The mean CPB time was of 97 +-16 min per patient and the mean cross clamping time was 70 +- 14.5 min. The mean number of distal anastomoses was 3.3 +-0.5 per patient. Results: Early mortality was 1.7%. Mean follow-up time was 6.1 +- 2.3 years. Freedom from cardiac death and ischemic events was 99.4%, and 91.3% at 9 years after the operation, respectively. No perioperative myocardial infarclionoccured. Conclusions: Arterial revascularization with BITAs and GEA can be considered safe with low perioperative risks and good mid-term results.
