A 62-year-old man with unstable angina due to severe narrowing of the left main trunk (LMT) was examined. Emergency bypass surgery was performed with an internal mammary artery graft, instead of a saphenous vein graft, because of the thickened, edematous ascending aorta. Postoperative coronary angiography showed the lesion of the LMT markedly regressing. Presumably, this stenotic lesion of the LMT was caused by active aortitis and was partially reversible by steroid administration both during and after surgery. Steroid therapy can be added to the list of treatments for cases of LMT disease associated with Takayasu's aortitis, if signs of active inflammation are present.
一名62岁男性因左主干（LMT）严重狭窄导致不稳定型心绞痛接受检查。由于升主动脉增厚、水肿，急诊搭桥手术采用了乳内动脉移植，而非大隐静脉移植。术后冠状动脉造影显示LMT病变明显消退。据推测，LMT的这种狭窄病变是由活动性主动脉炎引起的，在手术期间和术后通过使用类固醇均可部分逆转。如果存在活动性炎症迹象，类固醇治疗可被列入与高安动脉炎相关的LMT疾病病例的治疗方法清单中。
