Abstract:
BACKGROUND: The aim of the current study was to assess the effects of total arterial myocardial revascularization (TAMR) with bilateral internal mammary arteries. MATERIAL AND METHOD: 139 consecutive patients who underwent off pump coronary artery bypass surgery from January 2000 to December 2001 were included in the current retrospective study. Patients were divided into those receiving bilateral internal mammary artery, BITA (n=85) and those receiving single internal mammary artery, SITA (n=54). RESULT: There was only one death in each group. No significant differences were noted in the total ICU and hospital stay; 2.4+/-1.7 and 11.2+/-17.7 days, in the BITA group, respectively and 2.8+/-2.7 and 9.7+/-7.1 days in the SITA group, respectively (P>0.05). The mean number of distal anastomosis of 3.9+/-0.7 was slightly higher in the BITA group compared to the SITA group, which was 3.1+/-0.8. Myocardial infarction occurred in 7 patients (BITA group: 2, SITA group: 5) and deep sternal infection necessitating reoperation occurred in 4 patients (BITA group: 3, SITA group: 1). Coronary angiogram was performed in the immediate postoperative period in 104 patients (BITA group: 64/85, SITA group: 40/54). Of these patients, stenosis in the LAD anastomosis site occurred in 4 patients (BITA group: 2, SITA group: 2). A total of 8 anastomotic sites were stenotic in the entire series of which percutaneous intervention was performed in 3 patients and none required reoperative coronary artery bypass. CONCLUSION: The results of the current data did not show a significant difference in patency rate with bilateral internal mammary artery use for CABG supporting the feasibility of its use as a viable alternative method for TAMR.
