Peripheral stent technology and current status for endovascular
treatment of femoropopliteal artery disease: a clinical review
Bhargav Dave*, Rikin Shah
INTRODUCTION
Globally, peripheral arterial disease (PAD) is estimated to
affect more than 200 million people. It is one of the
leading cause of morbidity and mortality which
predominantly affects the elderly population.

PAD
usually appears after the age of 50 years, with an
exponential increase after the age of 65. This rate reaches
around 20% by the age of 80.

Claudicating in PAD reduces walking distance and
impairs quality of life after the blood flow is limited in
the area. PAD in superficial femoral arteries (SFA) and
popliteal arteries (PPA) share common significant risk
factors for atherosclerosis. Quarterly of the total patients
with PAD present intermittent claudication (IC) and
progress to critical limb ischemia which leads to
significant disability and limb loss. Patients with
asymptomatic as well as symptomatic PAD are at an
increased risk of cardiovascular morbidity and mortality
compared with subjects without PAD.

Challenges in management of PAD with current
technology: focus on device characteristics
As per current standards, personal and family clinical
history of the patient should be assessed initially to detect
the presence of cardiovascular disease (CVD) as well as
LEAD to evaluate risk factors and co-morbidities.
Lifestyle habits and physical activities also need to be
systematically investigated to provide reasonably
accurate outcome measures and determine the

ABSTRACT
Over the past decade, the treatment of peripheral artery disease poses a number of technical challenges for the
physician. The primary rationale of this article is to review the available literature on the current practices involved in
the treatment of peripheral artery disease (PAD), particularly the femoropopliteal lesions. It is evident from the
landmark clinical trials that the use of self-expanding drug-eluting stents (DES) has become the most favored clinical
strategy for treating peripheral lesions above the knee. It is chiefly due to higher patency rates, and minimal in-stent
restenosis and stent fracture rates associated with the use of DES. The technical evolution in the endovascular
approach from the use of bare nitinol stents to DES for treating PAD and the factors responsible for this
transformation have also been reviewed with their respective justification. Presently there is a need of DES
technology for the treatment of femoropopliteal lesions, which can reduce the risk of stent fracture and in-stent
restenosis for longer lesions while maintaining patency during long-term follow-up. To conclude, this review
establishes that self-expanding DES and drug coated balloons using anti-proliferative drugs like sirolimus and
paclitaxel are currently the most effective method of treating the femoropopliteal lesions in PAD.
