A histology and immunochemistry study comparing open versus close and open-method endoscopic saphenous vein harvesting.

Background

The introduction of endoscopic saphenous vein harvesting (ESVH) has been reported to reduce wound pain and infection, compared with open saphenous vein harvesting (OSVH) techniques. There are still controversies regarding this technique. The aim of our study is to investigate the endothelial preservation of saphenous vein (SV) grafts harvested by different techniques. Further observations were made for harvesting and closure time, incision length and effect of pressure distension of the veins to the vein endothelium.

Methods

Prospective observational study of sixty human saphenous vein grafts was performed to evaluate endothelial preservation by haematoxylin-eosin and Cluster of Differentiation 31 (CD 31) staining. Saphenous vein was harvested endoscopically either by closed CO

Results

Open CO

Conclusion

We observed more endothelial detachment in the open CO
