There is an increasing incidence of infective endocarditis secondary to central venous catheters, which is termed as 'healthcare-associated infective endocarditis'. There is an increased risk of getting infective endocarditis in conditions with malnutrition and also if the tip of the central venous catheter is deep in the right atrium close to the tricuspid valve. We present a case of 31-year-old female who had all these risk factors. She was admitted to the hospital for the work up of the weight loss and was diagnosed with celiac disease. Central venous access was obtained because of poor peripheral intravenous access via the peripherally inserted central catheter which was complicated by thrombosis and removed after three days of insertion, and she was started on anticoagulation. Two weeks after being discharged, she presented to the emergency department with fever, shortness of breath, and had signs of congestive heart failure. A computed tomography of the chest for pulmonary embolism was taken and showed small clot burden pulmonary embolism and two cavitary lesions in the right lung. A transthoracic echocardiogram was taken and showed vegetation on the tricuspid valve and blood cultures were positive for Staphylococcus aureus. Hence, a diagnosis of infective endocarditis was made, and she was treated with intravenous antibiotics for a total of six weeks after a long and complicated hospital stay.
中心静脉导管所致的感染性心内膜炎发病率不断上升,这种情况被称为“医疗保健相关感染性心内膜炎”。在营养不良的情况下,以及当中心静脉导管尖端深入右心房靠近三尖瓣时,发生感染性心内膜炎的风险会增加。我们报告一例31岁女性病例,她具备所有这些危险因素。她因体重减轻入院检查,被诊断为乳糜泻。由于外周静脉穿刺困难,通过外周置入中心静脉导管建立中心静脉通路,该导管出现血栓形成并发症,置入三天后拔除,随后她开始接受抗凝治疗。出院两周后,她因发热、气短就诊于急诊科,并有充血性心力衰竭体征。进行胸部计算机断层扫描以排查肺栓塞,结果显示有小负荷肺栓塞及右肺两个空洞性病变。进行经胸超声心动图检查,显示三尖瓣有赘生物,血培养金黄色葡萄球菌呈阳性。因此,诊断为感染性心内膜炎,经过漫长而复杂的住院治疗后,她接受了为期六周的静脉抗生素治疗。
