We retrospectively analyzed the revascularization of the septal artery achieved either directly through a coronary artery bypass graft (CABG) to the first septal artery (S1), or indirectly through endarterectomy and CABG of the anterior descending coronary artery (LAD). From July 1, 1976 to May 1, 1979, 21 84% (11 of 13). During the same period, 15 patients with a large S1 received endarterectomy and CABG of the LAD. Six of these 15 patients (40%) had an excellent flow into S1 as seen on the postoperative angiogram, whereas nine (60%) showed no improvement. The vein graft was patent and considered normal in 14 patients and the distal flow in the LAD was adequate in 10 patients (66%). We conclude that better revascularization of S1 is achieved by direct CABG. However, endarterectomy of the LAD allows revascularization of arteries that could not be grafted otherwise because of severe diffuse disease.
我们回顾性分析了通过冠状动脉旁路移植术（CABG）直接移植至第一间隔动脉（S1）或通过冠状动脉内膜切除术及前降支冠状动脉（LAD）的CABG间接实现的间隔动脉血运重建情况。1976年7月1日至1979年5月1日期间，21例患者中84%（13例中的11例）。同期，15例S1粗大的患者接受了LAD的内膜切除术及CABG。术后血管造影显示，这15例患者中有6例（40%）S1血流良好，而9例（60%）未见改善。14例患者的静脉移植物通畅且被视为正常，10例患者（66%）LAD的远端血流充足。我们得出结论，直接CABG能更好地实现S1的血运重建。然而，LAD的内膜切除术可使因严重弥漫性病变无法进行其他移植的动脉实现血运重建。
