Résumé
Objective To study a minimally invasive surgical procedure for coronary artery bypass grafting (GABG). Methods 23 patients, aged from 45 to 73 years old, undervent off-pump coronary artery bypass grafting (OPCABG) according to Octopus procedure from December 1999 to Auguest 2001. In the present study , more than 3 vessels were involved in 19 patients; 2 vessels involved in 3 cases and 1 vessel involved in one case. The grafted arteries included left anterior descending branch (LAD)(23); circumflex(CX)(15); right coronary artery(RCA)(14); ramus intermedius(RUM)(8); and posterior descending artery(PDA) (8). The types of grafts were left internal mammary artery (LIMA)(20) and saphenous vein grafts(SVG)(48). Results None of the patients was managed by means of cardiopulmonary bypass. All survived without angina pectoris. MRI showed that all the conduits were patent postoperatively. Conclusions OPCABG by Octopus procedure can be used in multiple vessel coronary bypass including CX and PDA. The patency rate is similar to that of the conventional technique. The mortality rate and occurrence of complications is low compared with those of the conventional technique . In addition, medical cost is lower. So This procedure is both safe and cost-effective, and is of value in clinical practice.
