Summary:
Background: The vacuum-asssited closure has represented an encouraging treatment modality in treatment of surgical site infection
in cardiac surgery, providing superior results compared with conventional treatment strategies, particularly in the treatment of deep sternal
wound infection.
Methods: From November 2004 to January 2007, 40 patients, undergoing VAC therapy (VAC system™, KCI, Austria, Hartmann-Rico
Inc., Czech Republic) for surgical site infection following cardiac surgery, were prospectively evaluated. Four patients (10%) were treated
for extensive leg-wound infection, 10 (25%) were treated for superficial sternal wound infection and 26 (65%) for deep sternal wound
infection. The median age was 69.9 ± 9.7 years and the median BMI was 33.2 ± 5.0 kg/m2. Twenty-three patients (57%) were women and
diabetes was present in 22 patients (55%). The VAC was employed after the previous failure of the conventional treatment strategy in 7
patients (18%).
Results: Thirty-eight patients (95%) were successfully healed. Two patients (5%) died, both of deep sternal infetion consequences.
The overall length of hospitalization was 36.4 ± 22.6 days. The median number of dressing changes was 4.6 ± 1.8. The median VAC treatment
time until surgical closure was 9.7 ± 3.9 days. The VAC therapy was solely used as a bridge to the definite wound closure. Four
patients (10%) with a chronic fistula were re-admitted with the range of 1 to 12 months after the VAC therapy.
Conclusion: The VAC therapy is a safe and reliable option in the treatment of surgical site infection in the field of cardiac surgery.
The VAC therapy can be considered as an effective adjunct to convetional treatment modalities for the therapy of extensive and life-threatening
wound infection following cardiac surgery, particurlarly in the group of high-risk patients.
