Abstract
Background Since the introduction of coronary stents, less than 40 cases of coronary stent infection have been reported worldwide. Although coronary stent infection is rare, the mortality rate is high. We report the first case of coronary stent infection from our institute, presented as pyrexia of unknown origin.
Case Presentation A 48-year-old male was presented with low-grade fever associated with cough and malaise on the 8th day of the PCI procedure. He priorly underwent a multivessel percutaneous coronary intervention (PCI) at another hospital. He was evaluated elsewhere and treated with antipyretics, but he continued to be symptomatic and failed to yield any conclusive diagnosis. He was referred to a higher center for further management.
Diagnosis and Intervention Post-PCI pyrexia of unknown origin was found with elevated C-reactive protein and leukocytosis, the whole-body positron emission tomography scan showed increased fluorodeoxyglucose uptake in the left atrioventricular groove along the stent, and blood culture grew Pseudomonas aeruginosa. He was treated with cefoperazone-sulbactam 3 gm twice daily for 4 weeks, followed by Tab. Ciprofloxacin 750 mg for 2 weeks, and the patient responded clinically. After 2 months, the patient presented with chest pain and underwent a coronary angiogram that revealed left circumflex (LCx) in-stent total occlusion with a pseudoaneurysm. He underwent coronary artery bypass grafting to the obtuse marginal and posterior descending artery. As the tissues could not be delineated, the stent was not retrieved from the LCx. His postoperative period was uneventful, and he did well at 2-year follow-up.
