It was reported that the procedure was to treat a left internal carotid artery.A non-abbott guide wire was advanced and placed and a emobshield nav6 embolic protection system (eps) was deployed.A non-abbott balloon catheter was advanced over a hi-torque pilot 200 guide wire.The balloon was inflated to 8 atmospheres (atm); however, was reduced to 6 atm as the patient began to experience local pain and bradycardia.One milligram of atropine was provided intravenously.The balloon was deflated and retracted a little and second inflation was performed at 8 atm.The eps removal was noted to be complicated as there was resistance during advancement of the retrieval catheter through the unspecified deployed stent requiring to advance a non-abbott 6-f guide sheath to remove the filter successfully.There was no clinically significant delay reported.Serial doppler ultrasound was performed at day 1, 1 month, and 6 months post procedure and revealed a decrease in peak systolic velocity and a consistent 20-49% restenosis.Details are listed in the article, titled: drug-eluting balloon angioplasty for in-stent restenosis following carotid artery stent placement.
