Abstract
Technological advances and increasing operator experience have improved the success rate of transvenous lead extraction (TLE). However, in some cases—especially with longer lead dwelling time—TLE can be highly complicated. In this case report, the authors present an unusual case of implantable cardioverter defibrillator (ICD) pocket infection diagnosed by 18F‑fluorodeoxyglucose positron emission tomography/computed tomography (18F‑FDG-PET/CT). Complete lead extraction required a combined transvenous and surgical approach. Contralateral reimplantation failed due to occlusion of the right brachiocephalic vein. Therefore, a subcutaneous ICD was implanted. This case highlights the importance of an interdisciplinary approach to the treatment of cardiac implantable electronic device infection.
Zusammenfassung
Technischer Fortschritt und zunehmende Erfahrung haben die Erfolgsrate transvenöser Sondenextraktionen (TLE) deutlich erhöht. In einigen Fällen, insbesondere bei seit längerer Zeit einliegenden Elektroden, kann eine TLE jedoch sehr kompliziert sein. In diesem Bericht präsentieren wir den ungewöhnlichen Fall der Tascheninfektion eines implantierbaren Kardioverter-Defibrillators (ICD), bei dem die endgültige Diagnose auf Basis einer 18F‑Fluordesoxyglukose-Positronenemissionstomographie/Computertomographie gestellt wurde. Eine vollständige Sondenextraktion war nur durch eine Kombination aus TLE und chirurgischem Eingriff möglich. Der Versuch einer Reimplantation auf der kontralateralen Seite war aufgrund eines Verschlusses der rechten V. brachiocephalica frustran, sodass wir uns für die Implantation eines subkutanen ICD entschieden. Der aktuelle Fall unterstreicht die Bedeutung eines interdisziplinären Ansatzes zur Behandlung von Infektionen im Zusammenhang mit einem kardialen implantierbaren elektronischen Gerät.
