From December 1994 to April 1995, nine patients were submitted to myocardial revascularization using Y arterial graft, which consists of internal thoracic artery (ITA) Y branched with inferior epigastric artery (IEA). The age ranged 50 to 76 (mean age, 67.2 years); seven patients were male. Five patients had three vessel CABG and four patients had four vessel CABG. There was no operative mortality and no mechanical supports with IABP. Aortic clamping and operative time was not longer in this series. Early postoperative angiographic evaluation of Y arterial grafts showed that nine ITA grafts were patent (100%) and seven IEA grafts were patent (77.8%). Because of the low patency rate of IEA graft, Y graft using IEA appears to be an interesting alternative only in patients who have no other available conduits.
1994年12月至1995年4月，9例患者接受了使用Y形动脉移植物的心肌血运重建术，该移植物由与腹壁下动脉（IEA）分支的胸廓内动脉（ITA）Y形组成。年龄范围为50至76岁（平均年龄67.2岁）；7例患者为男性。5例患者接受了三支血管冠状动脉旁路移植术（CABG），4例患者接受了四支血管CABG。无手术死亡，未使用主动脉内球囊反搏（IABP）进行机械支持。本系列中主动脉阻断和手术时间并不长。术后早期对Y形动脉移植物的血管造影评估显示，9支ITA移植物通畅（100%），7支IEA移植物通畅（77.8%）。由于IEA移植物的通畅率较低，仅在没有其他可用管道的患者中，使用IEA的Y形移植物似乎是一种有趣的替代方案。
