Estimated cost: Included in CABG package · Average stay: Part of CABG stay
Endoscopic vein harvesting (EVH) is a minimally invasive technique for harvesting the greater saphenous vein from the leg to use as a bypass graft conduit in coronary artery bypass surgery (CABG). Traditionally, vein harvest required a long incision extending the full length of the inner thigh and calf — a wound that took weeks to heal, frequently became infected, and left a prominent scar. Endoscopic vein harvesting replaces this large incision with a single small incision (2–3 cm) at the knee, through which a specially designed endoscope and cautery instrument harvest the entire vein under magnified video guidance.
The evidence for EVH is compelling. Randomized trials and meta-analyses demonstrate that EVH reduces major leg wound complications (wound infection, dehiscence, seroma, lymphedema) by 60–70% compared to open harvesting. Patient satisfaction with the leg cosmetic outcome is dramatically higher. Post-operative leg pain is significantly less, allowing earlier mobilization. Hospital stay may be slightly shorter. Long-term vein graft patency — a concern raised in some early retrospective studies — has been confirmed to be non-inferior to open harvesting in properly conducted randomized trials and registry data.
India's leading cardiac surgery centers — Apollo Hospitals, Medanta – The Medicity, Fortis, Max Hospital, and Narayana Institute of Cardiac Sciences — routinely offer EVH as the standard of care for saphenous vein harvest in CABG, at no additional cost over conventional harvesting. For international patients, this means access to a higher standard of surgical technique that reduces the most common post-operative complication (leg wound problems) associated with bypass surgery.
What is Endoscopic Vein Harvesting and How Does it Work?
The greater saphenous vein (GSV) is the longest vein in the body, running from the ankle up the inner thigh to the groin. It is the most commonly used bypass graft for coronary artery bypass surgery when the internal mammary artery alone is insufficient to bypass all blocked coronary arteries (most patients with two or three-vessel disease need one or two saphenous vein grafts in addition to the mammary artery).
During conventional "open" vein harvesting, the surgical team makes a continuous incision from below the knee to the groin — a wound of 30–60 cm that must heal in a lower limb with relatively poor blood supply (particularly in diabetic and elderly patients), creating significant risk of wound breakdown, seroma, cellulitis, and deep wound infection.
EVH uses a single 2–3 cm incision at the knee. A specially designed dissecting instrument with a built-in endoscopic camera is inserted under the skin, adjacent to the vein. The surgeon watches a real-time video display and uses electrothermal energy to carefully dissect the vein free from surrounding tissue, coagulate and divide all side branches, and harvest the full vein length — all through one tiny incision. The vein is prepared and used as the bypass graft exactly as in open harvesting. The single small incision is closed with absorbable sutures.
Who Benefits Most from EVH?
EVH is appropriate for all patients undergoing CABG who require saphenous vein grafts — but the benefit is greatest for: diabetic patients (who have the highest risk of open leg wound infection — 15–20% versus under 5% with EVH); obese patients (excess leg adipose tissue increases open wound risk dramatically); elderly patients with thin, friable skin and poor healing; patients with peripheral vascular disease; and patients with chronic leg edema or venous insufficiency.
Even in younger, healthier patients, EVH is preferred for the cosmetic benefit (no long scar), reduced leg pain, and faster return to normal ambulation. Some surgeons prefer open harvest for veins with thin walls, calcified atheroma, or very small caliber (under 3 mm) — the endoscopic view may make judgment of vein quality slightly more challenging in these cases, though modern EVH systems with high-definition cameras have largely overcome this limitation.
The EVH Procedure Step-by-Step
EVH is performed simultaneously with the cardiac surgical team's preparation for sternotomy and bypass cannulation, so it adds no time to the overall bypass operation.
A 2–3 cm incision is made just below or above the knee. The endoscopic harvesting device is inserted, and the surgeon identifies the saphenous vein under the camera view. The device gently tents the tissue over the vein while ultrasonic or electrothermal energy dissects branches. Hemoclips or bipolar energy seals side branches. The entire vein — typically 25–40 cm — is harvested and passed off the sterile field for preparation.
The leg incision is closed with two or three absorbable sutures, covered with a waterproof dressing. No long bandage or stockings are required from the ankle to the groin. Patients typically have minimal leg pain and can walk within 6–12 hours of surgery.
Procedure Steps
- Marking: GSV mapped by ultrasound preoperatively to confirm patency and suitability.
- Single incision: 2–3 cm incision made medially at knee level; dissection plane established around the vein.
- Endoscopic harvest: EVH device introduced; camera visualizes vein and side branches; branches sealed and divided with bipolar or ultrasonic energy.
- Vein extraction: full vein segment extracted through the small incision.
- Vein preparation: side branch stumps checked and tied; vein distended with heparinized blood to check for leaks.
- Wound closure: single incision closed with 2–3 interrupted absorbable sutures; sterile dressing applied.
- Post-harvest: leg elevated when in bed for first 24 hours; ambulation permitted within 12 hours.

EVH is included within the CABG package at India's leading cardiac centers — it is not charged separately. The EVH device and disposable instruments add a modest per-case cost that leading Indian hospitals absorb within their CABG pricing. Gaf Healthcare confirms that EVH is standard practice at recommended partner hospitals before arranging bypass surgery.
Recovery & Follow-up
EVH dramatically simplifies leg recovery after bypass surgery. Most patients find the single knee incision heals within 10–14 days. There is minimal wound care required — the dressing can be changed to a waterproof film every 2–3 days, and showering is permitted within 48–72 hours. Leg pain is mild and typically controlled with oral analgesics for the first 2–3 days.
Compared to open vein harvest, EVH patients: walk more easily and at an earlier stage; experience less leg swelling; have a substantially reduced risk of wound complications requiring antibiotics or wound care; and are significantly more satisfied with the cosmetic appearance of the leg. These benefits translate directly into faster overall recovery from the bypass operation.
Recovery Tips
- Keep the knee incision clean and dry for 48–72 hours; then waterproof dressings allow showering.
- Elevate the leg when sitting or lying for the first week to minimize swelling.
- Walk short distances regularly (every 1–2 hours during the day) from day one to promote healing and prevent DVT.
- Wear comfortable, non-constrictive footwear — no need for long compression stockings over the thigh.
- Report any increasing redness, warmth, or discharge from the incision site.
- The small knee scar fades to a thin line within 3–6 months.
Risks & Complications
EVH is a very safe technique with a complication rate well below open vein harvest. The small risk of EVH-specific complications includes: vein injury during harvesting (resulting in graft unusability — rare with experienced harvesters); small wound complications at the single incision site (under 3%); temporary leg numbness from the saphenous nerve (medial knee numbness — usually resolves within 3–6 months); and seroma at the incision site (2–3% — managed conservatively). The evidence is clear that EVH substantially reduces net leg complications compared to open harvesting.

Frequently Asked Questions
What is endoscopic vein harvesting?
Endoscopic vein harvesting is a minimally invasive technique to remove the saphenous vein from the leg through a single small incision (2–3 cm at the knee) rather than a long leg incision. A camera-guided instrument harvests the full vein length under video visualization, dramatically reducing leg wound complications.
Does EVH affect graft quality?
Well-performed EVH produces vein grafts of equivalent quality to open harvesting. Long-term coronary bypass graft patency is non-inferior when EVH is performed by experienced surgeons. The key is surgeon experience and the use of modern high-definition EVH systems.
Is EVH available at all cardiac centers in India?
EVH is standard at India's leading cardiac centers including Apollo, Medanta, Fortis, Max Hospital, and Narayana. Gaf Healthcare specifically confirms EVH availability at all recommended bypass surgery hospitals.
Will I have a scar after EVH?
You will have a single small scar (2–3 cm) at the knee. This fades to a thin line within 3–6 months. Compared to the 30–60 cm scar of open vein harvesting, EVH is dramatically better cosmetically.
