ZEPHYR registry identifies predictors of restenosis after PES implantation for femoropopliteal lesions

July 30, 2015

Lesion length of at least 16 cm, distal external elastic membrane area of 27 mm2 or less and minimum stent area of 12 mm2 or less were independent predictors of restenosis at 1 year among patients with peripheral artery disease who received a paclitaxel-eluting stent for femoropopliteal lesions, according to new data from the ZEPHYR registry.

Researchers performed a prospective, multicenter study to investigate the rate and predictive risk factors of 1-year restenosis in 690 patients in the ZEPHYR registry who were implanted with the Zilver PTX (Cook Medical) paclitaxel-eluting stent (PES). The study included 831 femoropopliteal lesions in 797 limbs. The mean lesion length was 17 ± 10 cm.
