Multicenter Study Controlled Clinical TrialCarotid artery revascularization in high surgical risk patients with the NexStent and the Filterwire EX/EZ: 1-year results in the CABERNET trial.
The multicenter, single-arm CABERNET trial evaluated outcomes in high-surgical-risk patients with carotid artery stenosis treated with the NexStent plus FilterWire EX/EZ Emboli Protection System. ⋯ The CABERNET trial demonstrates that CAS with NexStent and FilterWire is noninferior to (equivalent or better than) traditional CEA at 1 year in high-surgical-risk patients based on historical controls.

Case ReportsProtamine usage following implantation of drug-eluting stents: a word of caution.
The treatment of hemorrhagic complications of percutaneous interventions with protamine is an accepted practice. Concerns exist about the increased thrombo-genicity of drug-eluting stents. We report two cases of acute stent thrombosis following drug-eluting stent implantation related to protamine administration.

Case ReportsCarotid sheath rescue with a distal filter retrieval catheter.
Sheath placement prior to carotid artery stenting is usually uncomplicated, and provides sufficient support for the procedure. In certain patients, especially those with unfavorable arch anatomy, tortuous vessels, and heavily calcified lesions, the sheath backs out into the aortic arch with compromise of wire and embolic protection device (EPD) position, and risk of "dragging" the EPD back through the lesion. ⋯ Use of the filter retrieval catheter as a "body" to retrack the sheath but not recapturing the deployed filter is a useful technique, since the equipment is already available. This avoided the need to pull a retrieved filter through a severe undilated carotid stenosis, reducing the amount of manipulations needed to reposition the sheath and thus reducing the risk of embolic events.
