ABSTRACT
A young female patient with Takayasu arteritis presented with unstable angina due to bilateral coronary artery involvement. Steroid pulse therapy and subsequent prednisolone administration were started, but early coronary artery bypass grafting was required because of the multiple angina attacks at rest, with a prednisolone dose of 22.5â¯mg (0.45â¯mg/kg/day). Since the left internal thoracic artery which was grafted to the left anterior descending artery resulted in graft failure a few days after the surgery, the immunosuppressive therapy was intensified with the addition of tocilizumab and methotrexate. After controlling the disease activity, coronary ostial angioplasty using external iliac artery grafts was successfully performed, with a prednisolone dose of 15â¯mg (0.3â¯mg/kg/day). Ten months after the operation, the patient has been free from chest pain. The present case demonstrated the importance of adequate preoperative immunosuppressive therapy, even when early surgical intervention is required. Learning objective:
There are no established treatment regimens for immunosuppressive management in cases of Takayasu arteritis (TAK) requiring immediate surgical intervention. Even when early surgery is required, it is important to reduce disease activity with appropriate preoperative immunosuppressive therapy using steroids in addition to biological agents, such as tocilizumab. Coronary ostial angioplasty is the effective surgical revascularization technique for TAK with coronary artery involvement.
