The described internal mammary artery (IMA) preparation reduces several shortcomings of the IMA graft procedure. The technique increases vessel diameter through single plane pedicle fascial incision assisted by gentle balloon dilatation. Trauma to the intima from instrumentation is minimized due to the atraumatic nature of a soft air-filled balloon catheter and avoidance of shear forces exceeding 40 g. The increase in vessel diameter effected by balloon dilatation creates a larger hood area to facilitate the distal anastomosis. The technique also maximizes the length of the IMA for sequential grafting.
所描述的乳内动脉（IMA）制备方法减少了IMA移植手术的一些缺点。该技术通过在轻柔球囊扩张辅助下的单平面蒂筋膜切口增加血管直径。由于柔软的充气气球导管无创伤性且避免了超过40克的剪切力，器械对内膜的创伤最小化。球囊扩张导致的血管直径增加创造了更大的覆盖区域，便于进行远端吻合。该技术还能最大限度地增加IMA用于序贯移植的长度。
