Background: Coronary involvement in Takayasu’s arteritis is a rare but fatal disease. The aim of this study was to evaluate the early and mid-term results of Takayasu’s arteritis patients who underwent coronary artery bypass grafting (CABG). Methods: Of 2,280 patients who underwent isolated CABG from January 1998 to June 2012, Takayasu’s arteritis was identified in 5 patients. There were 3 female patients, and the mean age was 58±9 years. Takayasu’s arteritis was diagnosed during preoperative evaluation for coronary artery disease in 4 patients, and the initial manifestation was angina pectoris in 4 patients. All of the patients underwent anaortic off-pump CABG (OPCAB) using the in situ left or right internal thoracic arteries (ITA); 3 patients had severe stenosis of the proximal left subclavian artery and the in situ right ITA was used instead. Medical treatment for inflammatory arteritis during the perioperative and follow-up period was performed if indicated. Early, 1-year, and 5-year angiographic results and clinical outcomes were analyzed. Results: There was no surgical mortality, and all of the patients were discharged without complications on postoperative 8±2 days. Early postoperative (postoperative 2±1 days) angiography demonstrated a graft patency of 100% (12 of 12 distal anastomoses). One-year (13±3 months) angiography was performed in 4 patients, and all of the grafts were patent (100%, 9 of 9 distal anastomoses). Conclusion: By performing anaortic OPCAB in patients with Takayasu’s arteritis, we were able to avoid complications associated with manipulating an atherosclerotic and severely calcified ascending aorta. The early and mid-term graft patency of OPCAB in Takayasu’s arteritis was maintained when concomitant with medical treatment.
