New Innovations in Drug-Eluting Stents for Peripheral Arterial Disease.

Purpose Of Review: The purpose of this paper was to provide a review of the burden of peripheral arterial disease; to examine older therapies and their limitations; and especially to highlight new treatment innovations as well as the data supporting their use.

Recent Findings: Building on the success of paclitaxel in the prevention of restenosis in the peripheral circulation, the newest generation drug-eluting stent is presented, which combines paclitaxel with a polymer-allowing the drug to be eluted slowly over 12 months. The positive results of the pilot MAJESTIC study led to the ongoing IMPERIAL trial.

Renal artery aneurysm and arteriovenous fistula associated with fibromuscular dysplasia: successful treatment with detachable coils.

Renal artery aneurysms are more common in patients with fibromuscular dysplasia (FMD). Although these aneurysms have traditionally been managed surgically, endovascular techniques are playing a larger role. Many treatment methods involve the use of stent-grafts to exclude the aneurysm or bare stents to protect the main renal artery while coil embolization is performed through the interstices.
