Preliminary Report of Off-Pump Coronary Artery Bypass Grafting (OPCABG) at Lampang Hospital
Keywords:
Myocardial revascularization, Coronary artery bypass grafting, Off-pump coronary artery bypass graftingAbstract
Objective: Conventional coronary artery bypass grafting (CABG) is the standard treatment for patients with coronary artery heart disease. However, its major and life threatening complications include stroke and renal dysfunction. Off-pump coronary bypass grafting (OPCABG), by avoiding cardiopulmonary bypass, may reduce these complications.
Patients and Methods: We retrospectively reviewed the records of 125 consecutive patients (male 59 cases, female 66 cases) who underwent elective OPCABG from April 2011 through September 2013.The mean age (sd) was 63.8 ± 8.6 years. Left main disease was present in 24.8%. Preoperative renal insufficiency (Cr > 2.5 mg/dl) was seen in 20% of cases while previous stroke was found in 2.4%. Mean Euroscore (sd) was 6.65 ± 2.9. Results: Mean graft per patient (sd) was 3.4 ± 1.1. The internal mammary artery was used in 84.8% of cases. Endarterectomy was performed in 11 patients (9.1%). Total arterial grafting was performed in 20 patients (16.0%). Conversion to on-pump technique occurred in 2 cases (1.6%); 2 patients died within 30 days (1.6%); and late deaths occurred in 4 cases (3.2%). Renal dysfunction requiring dialysis occurred in 1 (0.79%), and re-exploration for bleeding occurred in 2 cases (1.6%). There were no stroke events and no sternal wound infections. The mean follow-up time (sd) was 16.4 ± 11.03 months.
Conclusions: Early results of OPCABG at Lampang hospital were promising, with no mortality and low morbidity.
