    Insights

    Carotid artery stenosis treatment involves surgery or stenting, especially for symptomatic cases. Patient selection and advanced stent technology are crucial for reducing stroke risk during endovascular procedures.

    Area of Science:

    • Vascular Surgery
    • Interventional Cardiology
    • Neurology

    Background:

    • Extracranial internal carotid artery (ICA) stenosis is treated with surgical endarterectomy (CEA) or endovascular stent implantation (CAS).
    • Revascularization is recommended for symptomatic ICA stenosis (50-99%) and selected asymptomatic cases (60-99%).
    • Optimal medical therapy is the primary treatment for asymptomatic stenosis, with revascularization considered based on individual risk assessment.

    Purpose of the Study:

    • To review current guidelines and treatment considerations for extracranial internal carotid artery stenosis.
    • To highlight the importance of patient selection and technological advancements in endovascular revascularization.
    • To emphasize the role of interdisciplinary decision-making in choosing between CEA and CAS.

    Main Methods:

    • Review of current guidelines and relevant studies on carotid artery stenosis treatment.
    • Analysis of factors influencing the choice between surgical and endovascular revascularization.
    • Discussion of technological advancements in carotid artery stenting (CAS).

    Main Results:

    • Both CEA and CAS are established treatments, with specific indications based on stenosis severity and symptoms.
    • Endovascular therapy (CAS) is associated with a higher incidence of minor strokes and transient ischemic attacks (TIAs).
    • Patient selection and embolic protection are critical for safe and effective CAS.
    • Innovative stent designs improve plaque coverage and reduce peri-procedural stroke rates.

    Conclusions:

    • The choice between CEA and CAS requires an interdisciplinary approach, considering patient-specific and anatomical factors.
    • Technological advancements in CAS enhance safety and reduce complications.
    • Careful patient selection and procedural techniques are paramount for successful carotid revascularization.
