Further study details as provided by University of Oklahoma:

Primary Outcome Measures:
  • Superficial femoral artery late lumen loss [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • procedural success, amputation, target segment revascularization (TSR), target vessel revascularization (TVR), surgical revascularization, clinical restenosis defined by increase in Rutherford claudication grade of 1 or more [ Time Frame: 12 months ]

Enrollment: 27
Study Start Date: January 2009
Study Completion Date: April 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Paclitaxel
Participants will receive Paclitaxel.
Drug: Paclitaxel
Paclitaxel will be administered intra-arterially through an irrigating catheter to treat a diseased segment of superficial femoral artery. Dosing will be based on ther lesion surface area, and will be calculated using the following formula: dose= 22/7 X diameter (mm) X length (mm) X 3 micrograms/mm^3

Detailed Description:
Treatment of superficial femoral artery atherosclerosis with percutaneous techniques is hindered by high restenosis rates. Paclitaxel inhibits restenosis in coronary arteries, and a few studies suggest it may be effective in reducing restenosis rates in peripheral arteries. The investigators hypothesize that delivering paclitaxel through an irrigating catheter will be superior in preventing restenosis.
