  • Title: [Two cases of left main trunk lesion treated with coronary artery bypass grafting the proximal circumflex coronary artery (# 11)].

    Journal: Kyobu Geka; 2001 Mar; 54(3):215-8. PubMed ID: 11244754.
    Abstract:
    Two cases are reported of coronary artery bypass graft (CABG) surgery to the proximal left circumflex artery (LCX) system and left anterior descending artery (LAD) system. Both patients suffered from unstable angina due to left main trunk (LMT) lesions and required semi-emergent coronary revascularization. In both cases, the obtuse marginal branch and postero-lateral branch were too small to be grafted, although there are the usual target branches in the LCX system. CABG to the proximal portion (# 11) of LCX in the atrioventricular groove using saphenous vein grafts was performed and good blood flow rates were seen intra-operatively. Both patients recovered uneventfully and had no recurrence of anginal attacks. Postoperative coronary angiography confirmed good graft patency and an adequate coronary blood supply. CABG to LCX (# 11) is feasible without special techniques or tools. This method seems to be useful in patients with LMT lesions or with proximal lesions of LCX in which the branches are too small to be grafted.
