The full length of the radial artery from 1 cm of its origin to fistula anatomosis will be treated with paclitaxel. In addition the anastomosis and first 4 cm of the fistula vein will be treated. Paclitaxel solution treatment of each lesion encountered will be attempted until the 20 mg Paclitaxel dose limit is met. The volume administered will depend on the diameter and length of the vessels treated. Maximization of the length of vessel and lesions treated will be undertaken when there are more lesions than can be accommodated by the 12 mg, 10 ml dose available.
