Proposed Diagnostic and Management Pathway in Coronary Stent Abscess

Patients with recent PCI presenting with fever, recurrent ischemia, or new pseudoaneurysm should undergo structured evaluation including blood cultures and coronary imaging. Negative PET imaging result does not exclude infection. Prolonged targeted antimicrobial therapy and timely surgical source control represent the preferred management strategy, with percutaneous exclusion reserved for selected high-risk patients. CRP = C-reactive protein; CT = computed tomography; ESR = erythrocyte sedimentation rate; PCI = percutaneous coronary intervention; PET = positron emission tomography.
