Background
Infections and complex wounds after ventricular assist device (VAD) placement can result in significant morbidity and mortality. The purpose of this study was to evaluate complex wound management in the VAD patient, and to describe a treatment protocol for these challenging and potentially mortal complications.
Methods
A retrospective study was performed to examine all patients who underwent continuous flow, second-generation VAD placement at the Hospital of the University of Pennsylvania between March 2008 and April 2013.
Results
Overall, 150 VADs were placed, with 12 (8%) patients requiring 15 operative interventions by the plastic surgery services. The most common indication for operative intervention was a complicated wound with VAD exposure (5/12, 41.7%). All patients underwent aggressive operative debridement, and 11/12 (92%) underwent vascularized soft tissue coverage. Flaps commonly utilized included rectus abdominus myocutaneous (n = 4), rectus abdominus muscle (n = 4), pectoralis major (n = 3), and omentum (n = 3). Three patients experienced complications which required a return to the operating room, including 1 flap loss, 1 hematoma, and 1 wound dehiscence requiring further soft tissue coverage. Salvage was achieved, yet a 50% mortality rate in follow-up was noted.
Conclusion
Complex wound management in VAD patients can be achieved with aggressive debridement and vascularized soft tissue coverage, most commonly utilizing well-vascularized rectus abdominus muscle or omental flaps. Plastic surgeons should be familiar with the armamentarium at their disposal when approaching these challenging cases as VAD wound complications stand to become an increasingly prevalent issue.
