Purpose
The occurrence of cardiac pacemaker pocket infection has markedly increased and has become a new problem facing cardiovascular internists. The aim of our study was to investigate the effectiveness and safety of treating cardiac pacemaker pocket infection using negative-pressure wound therapy (NPWT) in patients who are unwilling or unable to have their cardiac implantable electronic devices (CIEDs) removed.
Methods
From March 2013 to April 2019, NPWT was applied to 26 patients with cardiac pacemaker pocket infection who were unwilling or unable to have their CIEDs removed. In the first stage, a negative-pressure drainage system was placed in the pacemaker pocket after debridement. Then, NPWT was used to seal the wound, and the negative pressure (300–400 mmHg) was sustained for 5–7 days. In the second stage, the pacemaker was relocated to the subpectoral layer, and the wound was closed.
Results
In all but three of our 26 patients, the wound healed completely without complications and without evidence of residual infection. The average follow-up period was 26.92 ± 9.46 months. Only 3 diabetic patients whose tissue bacterial cultures revealed that methicillin-resistant Staphylococcus epidermidis developed uncontrolled infections. Eventually, the entire original pacemaker systems were removed, and new pacemakers were implanted in the contralateral chest wall.
Conclusions
When warranted by strictly selected indications, the method of NPWT without CIED extraction can be considered as a new and effective treatment for patients with pacemaker pocket infection who are unwilling or unable to have the device removed.
