Extrinsic arterial supply of the great saphenous vein: an anatomic study.

The extrinsic arterial supply to the great saphenous vein was studied by dissection following latex injection, diaphanisation and contrast roentgenograms. Arterial supply arises from the external pudendal, superficial femoral, superior genicular and posterior tibial arteries. These branches ensure the irrigation of the vasa vasorum. The role they play in the outcome of bypass with the great saphenous vein is a further argument pleading in favor of the in situ technique.
