영구형 박동 조율기 전극 감염과 관련된Actinobacillus actinomycetemcomitans균혈증 1예

저자들은 3개월간 지속된 발열을 주소로 내원한 영구형 박동 조율기가 있는 환자에서 99mTc-HMPAO 백혈구 스캔상 상대정맥에 위치한 박동 조율기 전극에 염증 소견이 관찰되었고 혈액 배양 검사상 Actinobacillus actinomycetemcomitans이 동정되어 이 미생물에 의한 박동 조율기 전극 감염으로 진단하고 박동 조율기의 제거 없이 항균제만으로 성공적으로 치료된 증례를 문헌 고찰과 함께 보고하는 바이다. A 73-year-old man was admitted for intermittent episodes of fever and chills for 3 months. He had been implanted with a permanent pacemaker to control tachy-bradycardia syndrome 7 months before admission. Blood cultures were positive for Actinobacillus actinomycetemcomitans and a 99mTc-hexamethylpropylene amine oxime (99mTc-HMPAO) WBC scan revealed inflammation on the pacemaker lead in extracardiac site. Oral examination revealed several dental caries. The patient was treated with intravenous ceftriaxone, followed by oral ciprofloxacin without removal of the infected pacemaker lead. He was doing well 10 months without febrile episodes after discontinuation of antibiotics. This report describes the first case of A. actinomycetemcomitans bacteremia associated with a pacemaker lead and localized by 99mTc-HMPAO WBC scan KCI Citation Count: 0
