Recurrent in-stent restenosis of the coronary artery is a rare but intractable problem. In this situation, coronary arteritis should be considered as an etiology. This case highlights the use of immunosuppressive drugs, including tocilizumab, and follow-up F-18-fluorodeoxyglucose positron emission tomography/computed tomography to break the vicious circle of recurrent stenosis caused by isolated coronary arteritis of unknown cause.
冠状动脉支架内再狭窄是一个罕见但棘手的问题。在这种情况下,应考虑冠状动脉炎作为病因。本病例突出了使用包括托珠单抗在内的免疫抑制药物,以及后续的F-18氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描,以打破由不明原因的孤立性冠状动脉炎引起的再狭窄恶性循环。
