Emerging interventional radiology treatment with drug-eluting stents saves limbs, study finds

In the United States, more than 100,000 amputations are performed each year on individuals with critical limb ischemia, the most severe form of peripheral arterial disease (PAD). The number one priority in treating these patients is to re-establish blood flow to avoid limb amputation. Interventional radiologists have found that a subgroup of patients with critical limb ischemia may avoid amputation through the use of drug-eluting stents on the smaller arteries below the knee, according to a new study.
