Which complication is commonly associated with the saphenous vein harvest site after CABG?

• A. Wound infection
• B. Leg edema
• C. DVT
• D. Sensory changes

Answer: (A)

Wound infection at the harvest site is the most common local complication after saphenous vein harvesting for CABG. Making a long leg incision to obtain the vein creates a sizable area susceptible to bacterial contamination and impaired healing, especially with factors like edema, obesity, diabetes, and smoking. Infections can delay wound healing, require antibiotics, and sometimes lead to dehiscence or additional interventions. While leg edema, deep vein thrombosis, and sensory changes from nerve injury can occur after CABG, they are less specifically linked to the harvest site itself and are not as commonly observed as infections at that incision. Maintaining sterile technique, appropriate perioperative antibiotics, meticulous wound care, and early mobilization help reduce the risk of harvest-site infection.
