"Extended length" endoscopic harvest of the great saphenous vein for coronary artery bypass grafting

Introduction: The endoscopically harvested vein from thigh usually falls short by half to one length in patients requiring multiple conduits. Increased risk of complications precludes routine endoscopic vein harvest from the leg and an extra incision for open technique is often required thereby nullifying the sole purpose of the former. We employed the endoscope to harvest this extra length of vein from the upper half of the leg with little or no extra risk. Methods: From January 2006 to September 2006 we endoscopically harvested the vein in thigh as well as the leg using the same entry point incision over the medial epicondyle in 40 cases. The only exclusion criterion for the study was a superficial location and subcutaneous visibility of the vein in the leg. We made 3 incisions in each patient of average size 2.5 cm. Results: Five patients required conversion to the open technique. The average harvest time was 59 minutes. Average length of the conduit was 48 cms. Complications included 1 minor wound infection, 1 case of superificial wound dehiscence, 1 haematoma requiring aspiration and minor erythema at the incision site in 2 patients. Most common complication observed was ecchymosis in 6 patients (5 high; 3 leg). None of the patient developed lymphoedema and none required re-hospitalization for vein harvest related wound complications. Conclusion: "Extended endoscopic vein harvest" and avoidance of the open incision was possible in most patients with no additional risk and that the procedure could be routinely employed in patients requiring multiple conduits. © 2007 Indian Association of Cardiovascular-Thoracic Surgeons.
