One of the limiting factors for the use of the right internal mammary artery as a pedicle graft to the anterolateral vessels of the left coronary system is the necessary midline crossover and the close proximity to the sternum. In this setting, the right internal mammary artery pedicle is at increased risk of injury during sternal reentry and dissection. A technique is described where stented polytetrafluoroethylene grafts were used to shield right internal mammary artery pedicles. There were no operative deaths or polytetrafluoroethylene-related complications. The right internal mammary artery was patent with its target vessel well perfused in 6 restudied patients.
将右侧胸廓内动脉作为带蒂移植物用于左冠状动脉系统前外侧血管的限制因素之一是必要的中线交叉以及与胸骨的紧密相邻。在这种情况下，右侧胸廓内动脉蒂在胸骨再次切开和解剖过程中受伤的风险增加。本文描述了一种使用带支架的聚四氟乙烯移植物来保护右侧胸廓内动脉蒂的技术。没有手术死亡或与聚四氟乙烯相关的并发症。在6例再次研究的患者中，右侧胸廓内动脉通畅，其靶血管灌注良好。
