Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical trial of stents versus angioplasty for the treatment of iliac artery occlusions (STAG trial).
The management of total iliac artery occlusion is now undertaken routinely using percutaneous techniques but there are no controlled data to indicate whether either balloon angioplasty or stent placement is preferable. This was a multicentre randomized trial to assess whether stents confer any safety or efficacy advantage over balloon angioplasty for complete iliac artery occlusion. ⋯ ISRCTN 48145465 (http://www.controlled-trials.com).

Randomized Controlled Trial
Randomized clinical trial of angiotensin-converting enzyme inhibitor, ramipril, in patients with intermittent claudication.
The aim was to investigate the effect of ramipril on clinical parameters in patients with peripheral arterial disease. ⋯ NCT01037530 (http://www.clinicaltrials.gov).

Randomized Controlled Trial Comparative Study
Economic analysis of a randomized trial of percutaneous angioplasty, supervised exercise or combined treatment for intermittent claudication due to femoropopliteal arterial disease.
The aim was to compare costs and utilities of percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA + SEP) in patients with intermittent claudication (IC) to establish the most cost-effective treatment. ⋯ Supervised exercise is the most cost-effective first-line treatment for IC, and when combined with PTA is more cost-effective than PTA alone.

The aim was to perform an economic evaluation of the cost-effectiveness of endovascular enhancements to percutaneous transluminal balloon angioplasty (PTA) with bail-out bare metal stents for infrainguinal peripheral arterial disease. ⋯ The use of drug-coated balloons represents a cost-effective alternative to the use of PTA with bail-out bare metal stents.
