Background: Infection of the percutaneous site of a ventricular assist device (VAD) is a challenging complication. We report our experience with crystal violet Solbase (Nihon University crystal violet method) for prevention of driveline or cannula infections in VAD patients.
Patients and Methods: The crystal violet method was used in 10 patients (prophylaxis in nine and treatment in one). Eight patients had an extracorporeal VAD (Nipro) and two had an implantable VAD (Heart Mate II).
Results: The infection-free period was 4-623 days (mean: 144.2 +/- 222.9 days). All eight patients with an extracorporeal VAD died, while the two patients with an implantable VAD (Heart Mate II) survived. Infection was improved in a patient with MRSA, and the results of bacteriological examination were always negative in the patients receiving prophylaxis. The two patients with an implantable VAD had no infection for 2 and 20 months after implantation.
Conclusion: These findings suggest that the Nihon University crystal violet method is effective for prevention and treatment of driveline or cannula infections in patients with a VAD.
