  Purpose

The purpose of the study is to determine the response to aspirin (ASA) and Clopidogrel in patients with peripheral arterial occlusive disease (PAOD) requiring interventional procedures and to investigate if patients with "resistance" to ASA or Clopidogrel have an unfavourable outcome during long-term follow-up
