Clinical Trial Summary

Background and purpose. Even if periprocedural cerebral microembolism associated with carotid endarterectomy or stenting usually does not manifest as clinically overt stroke, neuropsychological disturbances resulting from these events represent an important clinical and socioeconomic problem. Still, it remains unclear whether the use proximal protection can lower the incidence of cerebral embolism associated with the treatment of carotid stenosis.

Materials and methods. This was a prospective randomised single-centre study, which was aimed at comparison of surgical eversion endarterectomy with stenting under proximal protection in symptomatic patients. The investigators evaluated the incidence of new ischaemic lesions revealed by the diffusion-weighted magnetic resonance imaging 2-4 days after the treatment and neurologic events.


Clinical Trial Description

The CARECarotid was a prospective randomised single-centre study, which was performed in the University Hospital in Kraków. It was planned to evaluate 50 patients presenting with symptomatic lesions of the internal carotid artery.

Patients were randomly assigned to one of the two treatment arms: surgical endarterectomy or carotid angioplasty with stenting under proximal protection. All patients provided their written informed consent to undergo the procedures and to participate in this trial.

In all surgical patients carotid endarterectomy will perform using the eversion technique. All surgical endarterectomies will perform under cervical block anaesthesia.

Perioperatively patients in the surgical arm received aspirin; other antiplatelet or anticoagulant agents were not administered during 5 days before surgery.

All procedures in carotid artery stenting will perform with proximal protection system - the Mo.Ma (Medtronic, Minneapolis, MN, USA) device. The investigators will implante stents that were tailored to the localisation of lesions and morphology of carotid arteries: Carotid Wallstent (Boston Scientific, Natick, MA, USA, and in patients with tortuous arteries Precise Pro RX (Cordis, Fremont, CA, USA) or Roadsaver (Terumo, Tokyo, Japan). Patients in the stent arm will receive clopidogrel 75 mg/day and aspirin 75 mg/day. These drugs were administered during 3 days before planned procedure and then 3-6 months after stent implantation. All patients will have MRI DWI performed before and 2-4 days after procedures in both groups. Within 6 months there will be an evaluation of the incidence of neurological events. ;
