Negative Pressure Dressing After Saphenous Vein Harvest

November 30, 2015 updated by: Dr. Paul Fedak, University of Calgary

Negative Pressure Dressing to Decrease the Incidence of Leg Wound Complications After CABG

This study will test the effectiveness of negative pressure wound therapy (using the VAC Prevena device, KCI Canada Inc.) applied to the saphenous vein harvest site after Coronary Artery Bypass Grafting (CABG). When initiated immediately after surgery, this intervention may decrease the incidence of wound infection and non-infectious wound complications. It may decrease wound discomfort and improve mobility and functional recovery of the leg.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Prevena device (Group A)
Group A will have the VAC Prevena portable device applied to the saphenous vein harvest site after standard wound closure following coronary artery bypass surgery.
This portable device is applied to initiate negative pressure therapy to a wound site.
Other Names:
  • Prevena Incision Management System
  • Prevena 125
  • PRE1001.S Prevena Incision Kit
No Intervention: Conventional dressing (Group B)
Group B will have conventional dry dressing applied to the saphenous vein harvest site after standard wound closure following coronary artery bypass surgery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from baseline ASEPSIS score of wound healing at 6 weeks.
Time Frame: Baseline and 6 weeks
The ASEPSIS quantitative wound scoring method will be used to assess patients' leg wound healing after saphenous vein harvesting for coronary artery bypass surgery.
Baseline and 6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total score of pain level.
Time Frame: Baseline and 6 weeks
Patients will be asked to evaluate the level of pain (using the Leg Incision Assessment Form) at the wound site after saphenous vein harvesting.
Baseline and 6 weeks
