Rekanalisation am Unterschenkel: PTA oder Stent?

Percutaneous transluminal angioplasty (PTA) and stent placement are currently accepted methods for endovascular treatment of critical limb ischemia, if infragenual vessels are involved. Outcome results in high technical success and satisfactory clinical results for treatment of infrapopliteal lesions with regard to patency rates and amputation-free survival. These treatment modalities are also safe for the patients. The question whether PAT alone or additional stent placement is the better choice, is still unanswered due to limited data.
