Aneurysmal degeneration of fluoropolymer-coated paclitaxel-eluting stent in the superficial femoral artery: a rising concern

Abstract Background Although several clinical reports demonstrated a durable patency rate after novel fluoropolymer-coated paclitaxel-eluting stent (Eluvia; Boston Scientific, Marlborough, MA, USA) placement, aneurysmal degeneration drug-eluting (Eluvia) placement has raised concerns. Here, we report case with progressive aneurysm formation on serial angiography and intravascular ultrasound over 50 months for superficial femoral artery atheromatous plaque. Case presentation A 79-year-old woman right leg intermittent claudication at 100 m distance was referred to our hospital. Pre-procedural showed long-segment severe stenosis from the middle-to-distal part of artery, 7 mm wide placed. However, patient had recurrence in lower extremity 25 thereafter. Angiography revealed de novo distal popliteal proximal in-stent restenosis. Subsequently, underwent endovascular therapy these lesions. In addition, time enlargement maximum vessel diameter 10.0 edge stent. Intermittent side recurred again (Eluvia). middle artery. Peri-stent contrast staining found site.
