BACKGROUND: Vein trauma after saphenectomy by endoscopic or longitudinal techniques may influence the progression of medial and intimal hyperplasia and ultimately affect graft patency. This study compared the histologic characteristics of saphenous veins after endoscopic and longitudinal harvest. METHODS: One hundred seventy patients who underwent elective coronary artery bypass grafting had saphenectomy performed endoscopically (n = 88) or by a longitudinal incision (n = 82). Cross-sectional specimens from endoscopically (n = 151) and longitudinally (n = 158) harvested veins were submitted for hematoxylin-eosin, trichrome, and elastin staining. Blinded histologic evaluation involved graded analysis of endothelial, smooth muscle, and elastic lamina continuity in addition to medial and adventitial connective tissue uniformity. RESULTS: Regardless of harvest technique, endothelial, elastic lamina, and smooth muscle continuity as well as medial and adventitial connective tissue uniformity were not significantly different. CONCLUSIONS: Minor histologic alterations occur during saphenectomy, however, endoscopically and longitudinally harvested saphenous veins are histologically similar.
