Abstract

Introduction

Coronary artery bypass grafting (CABG) associated with Endarterectomy is a high risk procedure. After the first report of coronary endarterectomy by Bailey et al in 1951, the preference for this surgical procedure was decreased due to increased morbidity and mortality In patients with total or subtotal large coronary artery obstructions in which there is no possibility to receive a conduit as graft for myocardial revascularisation, endarterectomy remains the procedure of choice. This study was designed to study early and midterm results of off pump coronary artery endarterectomy.

Methods

Of 172 Consecutive Off Pump CABG done at our institution from Jan 2003 to July 2005, 22 patients underwent supplementary coronary endarterectomy. 16 patients had chronic stable angina 4 had unstable angina two required emergency CABG with endarterectomy following perioperative infarction. The mean ejection fraction was 29.2±4.3 and all of the patients were in New York Heart Association (NYHA) III or IV. All patients were planned for complete total arterial revascularisation using Left Internal Mammary Artery (LIMA). Right Internal Mammary Artery (RIMA), Radial composite “Y” graft, Two patients operated for periop infarct received vein graft. In 16 patients closed endarterectomy was done in five patients double endarterectomy in single vessel was done to chase the plaque distally, in one patient open left anterior descending (LAD) endarterectomy with vein patch reconstruction was performed.

Results

There were no deaths. None of the procedures were converted to on pump operation. All endarterectomies and bypasses were performed on Beating Heart, all patients were completely revascularised. Peri operative cardiac enzymes studied showed no significant rise in the Creatinine Phoshpokinase (CPK)-Creatinine Phosphokinase myocardial Band (CPK-MB). The mean postoperative Ejection Fraction (EF) was 36.7%±7.2% which was significantly higher than the Preoperative one (p<.05). At the end of four months to one and half year 22 patients were in NYHA class I to II and all were angina free in canadian cardiovascular society class.f

Conclusions

Coronary End Arterectomy without cardiopulmonary bypass can be performed in patients who are expected to benefit from complete revascularisation. It can be performed with closed as well as open method. However to achieve complete endarterectomy by closed technique in some patients it is essential to chase the plaque. Early and mid term results are encouraging.
