The left internal thoracic artery lpa r;LITA) is the preferred graft with the best patency rate in coronary artery bypass grafting (CABG). To maximize its use, we developed a technique of grafting 2 distant coronary arteries with the LITA, using its distal portion segmented to construct a Y graft with either the in situ LITA or right internal thoracic artery (RITA). We applied this technique in 51 patients. The distal segment of the LITA was used to create a Y graft in 4 different configurations according to coronary pathology. Offpump grafting was performed in 11% of cases. The use of a distal segment of the LITA was thus extended not only to the left anterior descending artery and branches but also to the circumflex and right coronary artery territories.
左乳内动脉（LITA）是冠状动脉旁路移植术（CABG）中首选的移植血管，其通畅率最佳。为了最大限度地利用它，我们开发了一种用LITA移植2条远端冠状动脉的技术，利用其分段的远端部分与原位LITA或右乳内动脉（RITA）构建Y形移植血管。我们将此技术应用于51例患者。根据冠状动脉病变情况，LITA的远端段以4种不同构型用于构建Y形移植血管。11%的病例采用了非体外循环下移植。因此，LITA远端段的应用不仅扩展到左前降支及其分支，还扩展到了回旋支和右冠状动脉区域。
