ABSTRACT
The excellent long term-patency rates achieved using the internal thoracic arteries (ITAs) have expanded the variety of graft arrangements of these conduits for multivessel coronary revascularization. We encountered 2 patients who underwent multivessel coronary artery bypass, by using these terminal branches of the left ITA effectively. In both patients, LITAs were taken down using the skeletonization technique with a harmonic scalpel. One patient had 2 grafts using the off-pump technique with the Y-composite grafts constructed by the main LITA trunk and LITA terminal branch, which were anastomosed with the left anterior descending branch (LAD) and diagonal branch (D<sub>1</sub>), respectively. The other patient had 6 grafts under on-pump cardiac arrest, including the natural LITA terminal branches which were anastomosed with the LAD and D<sub>1</sub>. Postoperative multidetector computed tomography (MDCT) revealed excellent long-term patent grafts in both patients. In conclusion, the terminal branches of the ITA, if of suitable size and length, could be used effectively to construct a Y-anastomosis for the coronary arteries, when consideration for the size of the target coronaries and native-coronary blood flow competition.
