Brief Summary:
The PTA-Registry (PTA-REG) is a prospective health services research registry to monitor and follow-up patients with peripheral arterial disease undergoing endovascular peripheral intervention. The PTA-REG has an interdisciplinary approach: cardiologists, angiologists, and radiologists contributed actively to this registry.

Condition or disease Intervention/treatment
Efficacy/Long-term Effectiveness Endovascular Therapy in PAD Device: PTA, balloon angioplasty, stent

Detailed Description:
The registry was created for the following purposes: evaluation of the clinical effectiveness, safety and quality of the endovascular therapy, and history of the disease after endovascular therapy. The resulting specific research questions were determination of the technical and clinical success of the procedure, monitoring of periinterventional complications, evaluation of vessel patency, amputation rate, mortality, and major adverse cardiac events during the follow-up. In addition, the quality of life after endovascular peripheral intervention over a period of two years was evaluated.
