..In this article the origin or central venous stenosis and occlusion will be reviewed along with a practical approach on how to best manage this disease process...

..We also believe that this method can provide an opportunity to select the suitable forearm for making an arteriovenous fistula, in which the ipsilateral central vein will exhibit little restenosis...
