The third to eighth intercostal arteries (ICAs) were bilaterally dissected in 10 cadavers to assess their length and possible routes to coronary arteries if used as in situ grafts. The mean lengths for the intercostal arteries harvested were 27.0 +/- 2.9 cm on the left and 27.4 +/- 3.2 cm on the right. The shortest anatomic route to the coronary arteries of the in situ ICAs harvested was medial to the lung and either superior to or inferior to the hilum. By using either the superior or inferior routes in situ ICAs were long enough to reach the major coronary artery territories in all cadavers. The most suitable ICAs for grafting the coronary arteries and the shortest routes were as follows: left anterior descending--left fifth ICA by inferior route; circumflex coronary artery-left fifth ICA by inferior route; and right coronary artery-right seventh ICA by inferior route. We conclude that it is anatomically feasible to use the intercostal artery as an in situ graft in coronary artery operation.
在10具尸体上双侧解剖第三至第八肋间动脉（ICA），以评估其长度以及若用作原位移植物时通向冠状动脉的可能路径。所采集的肋间动脉的平均长度，左侧为27.0±2.9厘米，右侧为27.4±3.2厘米。所采集的原位ICA通向冠状动脉的最短解剖路径是在肺内侧，位于肺门上方或下方。通过使用上方或下方路径，原位ICA在所有尸体中都足够长，能够到达主要冠状动脉区域。用于冠状动脉移植最合适的ICA及其最短路径如下：左前降支——通过下方路径的左第五肋间动脉；冠状动脉回旋支——通过下方路径的左第五肋间动脉；右冠状动脉——通过下方路径的右第七肋间动脉。我们得出结论，在冠状动脉手术中使用肋间动脉作为原位移植物在解剖学上是可行的。
