Negative Pressure Dressing After Saphenous Vein Harvest

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.

Inclusion Criteria:

• Patients presenting for elective or semi-elective isolated first-time CABG surgery with harvesting of the greater saphenous vein.
• Must be 18 years or older.
• Must live with one hour driving distance from Calgary.
• Must provide written consent.

Exclusion Criteria:

• Previous CABG surgery or previous lower leg surgical intervention.
• In emergent need for surgery.
• Have severe peripheral vascular disease.
• Do not speak and read the English language.
• Have dialysis-dependent renal failure.
• Require chronic steroids.
• Unable to return to clinic for follow-up due to functional or cognitive impairment.
