Between September 1994 and January 1995, the inferior epigastric artery (IEA) was used as a free graft for direct coronary artery bypass grafting in 4 patients. The IEA is excised from its origin from the external iliac artery as a pedicle with an "oval cuff" of 3 mm in diameter to facilitate the direct anastomosis with the aorta. The 4-week postoperative angiographic study showed that the IEA grafts were patent in all patients. We found that the IEA varies in length, diameter, and the pattern of branching between patients and between the right and left sides in the same patient. The preoperative digital subtraction angiography was useful for evaluating the suitability of IEA.
1994年9月至1995年1月期间，4例患者采用腹壁下动脉（IEA）作为游离移植物进行直接冠状动脉旁路移植术。将腹壁下动脉从其起自髂外动脉处切下，形成一个直径3毫米的带“椭圆形套袖”的蒂，以便与主动脉直接吻合。术后4周的血管造影研究显示，所有患者的腹壁下动脉移植物均通畅。我们发现，腹壁下动脉在不同患者之间以及同一患者的左右侧之间，其长度、直径和分支模式存在差异。术前数字减影血管造影有助于评估腹壁下动脉的适用性。
