[CABG performed for LMT orifice stenosis 15 years after AVR in a case of aortitis syndrome].

The case is a 54-year-old female at age 39 years, she underwent aortic valve replacement (AVR) for aortic valve regurgitation (AR) due to aortitis syndrome at a certain hospital. At the 15th year after AVR she was diagnosed with unstable angina due to LMT orifice stenosis and underwent CABG at this hospital. A distal side of anastomosis was performed on the LAD branch seg 6, an artificial vascular patch was placed for the proximal side of anastomosis to prevent inflammation of the aortic wall from spreading to the proximal side of anastomosis. On the postoperative cardiac catheter examination, the graft was found to be patent well. In the case of CABG complicated with aortitis syndrome, stenosis and obstruction of the proximal side of anastomosis long time after surgery pose a problem. However, the method so as to perform a proximal anastomosis by placing an artificial vascular patch on the aortic wall is considered to be one of the useful means which can avoid such a problem.
