[Comment] Endovascular stenting in femoropopliteal arteries

Peripheral arterial disease (PAD) represents a major burden on public health worldwide. The number of affected patients has increased in both low-income and middle-income countries (by 28·7% for 2000–10) and high-income countries (by 13·1%).1 The strong association with ageing, tobacco smoking, and diabetes means that the prevalence of PAD will continue to increase in the coming years.1 Although undertreatment of patients with PAD is common in many countries, endovascular intervention has become the dominant modality for treatment of obstructive disease patterns, and various different devices have been investigated in clinical trials.
