Implantable cardioverter defibrillator lead endocarditis due to Brucella melitensis is a rare and life-threatening complication of brucellosis. Successful management requires a combination of medical treatment and device extraction. We present a case of relapsing brucellosis manifested as infective endocarditis colonizing the lead of the implantable cardioverter defibrillator with formation of vegetation on the lead. A 63-year-old male presented to the rehabilitation unit with hypotension. No other signs of infection were noted. The patient had a history of drinking unpasteurized milk since childhood and a previous episode of Brucella infective endocarditis. A transthoracic echocardiography showed an oscillating vegetation on the lead of the tip of the right atrial ICD, and the blood cultures were positive for Brucella melitensis. Surgical removal of the device was infeasible, and medical management was the only feasible option in this case.
由羊布鲁氏菌引起的植入式心脏复律除颤器导线心内膜炎是布鲁氏菌病一种罕见且危及生命的并发症。成功的治疗需要药物治疗和取出装置相结合。我们报告一例复发性布鲁氏菌病病例，表现为感染性心内膜炎，累及植入式心脏复律除颤器导线并在导线上形成赘生物。一名63岁男性因低血压入住康复科。未发现其他感染迹象。该患者自童年起有饮用未杀菌牛奶的病史，既往有布鲁氏菌感染性心内膜炎发作史。经胸超声心动图显示右心房植入式心脏复律除颤器尖端导线上有摆动的赘生物，血培养羊布鲁氏菌阳性。手术取出装置不可行，在此病例中药物治疗是唯一可行的选择。
