Area of Science:

  • Interventional Cardiology
  • Neurology
  • Vascular Surgery

Background:

  • Distal embolization of debris during percutaneous carotid artery stenting can cause neurologic events.
  • Cerebral protection devices, such as filter devices, may reduce the risk of embolization.
  • Evaluating the use of filter devices in carotid artery stenting is crucial for patient safety.

Purpose of the Study:

  • To assess the feasibility, safety, and efficacy of carotid artery stenting using a filter device for cerebral protection.
  • To determine the rate of neurologic complications associated with this technique.

Main Methods:

  • A prospective study involving 22 consecutive patients (30 lesions) with >70% internal carotid artery stenosis.
  • Carotid artery stenting was performed with filter device protection.

  • Patients were monitored for neurologic events during the procedure, hospitalization, and at 30-day follow-up.

    • Main Results:

    • Successful stent implantation was achieved in 29 of 30 lesions.
    • Filter devices were successfully positioned in all 29 cases.
    • Two patients experienced neurologic complications; one had a minor, transient stroke. No major embolic strokes occurred. One death was attributed to hyperperfusion syndrome.

    Conclusions:

    • Carotid artery stenting with filter protection is technically feasible, safe, and effective.
    • The use of filter devices is associated with a low incidence of embolic neurologic events.
    • Filter protection represents a valuable strategy for reducing embolic complications in carotid artery stenting.
