Carotid artery disease<\/h1>\nCarotid stenosis: what are the risks and treatment options?\nCarotid stenosis is a narrowing of the carotid artery, most often linked to atherosclerosis. Its main risk is neurological: fragments of plaque or a clot can migrate to the brain and cause a transient ischemic attack (TIA) or a stroke. \nWhy can carotid stenosis be dangerous?\nThe carotid arteries carry a large portion of the blood destined for the brain. When an atherosclerotic plaque develops, it can reduce the diameter of the artery but, more importantly, become a source of embolisms to the cerebral circulation, which exposes the patient to a TIA, a full-blown stroke, sometimes permanent after-effects, and more rarely, death.\n The risk is not the same for all patients. It depends in particular on whether the stenosis is symptomatic or not, the degree of narrowing, the stability of the plaque, and the patient’s overall cardiovascular profile.\n[\/et_pb_text][et_pb_button button_url=”https:\/\/dr-seban-chirurgien-vasculaire.com\/contact\/” button_text=”Learn more” button_alignment=”left” _builder_version=”4.27.6″ _module_preset=”default” custom_button=”on” button_text_size=”15px” button_bg_color=”#5382b6″ button_border_color=”rgba(0,0,0,0)” button_border_radius=”0px” button_letter_spacing=”2px” button_font=”|700||on|||||” button_icon=”5||divi||400″ background_layout=”dark” custom_padding=”15px|40px|15px|40px|true|true” locked=”off” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_button][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/dr-seban-chirurgien-vasculaire.com\/wp-content\/uploads\/2026\/04\/doctolib-ma.webp” title_text=”doctolib-ma” _builder_version=”4.27.6″ _module_preset=”default” z_index=”1″ width=”90%” module_alignment=”right” custom_margin_tablet=”0px||||false|false” custom_margin_last_edited=”off|desktop” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″][\/et_pb_image][et_pb_image src=”https:\/\/dr-seban-chirurgien-vasculaire.com\/wp-content\/uploads\/2026\/03\/acupuncture-design-four.webp” title_text=”acupuncture-design-four” _builder_version=”4.27.6″ _module_preset=”default” positioning=”absolute” position_origin_a=”bottom_left” horizontal_offset_tablet=”150px” horizontal_offset_phone=”0px” horizontal_offset_last_edited=”off|desktop” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ custom_padding_last_edited=”on|tablet” _builder_version=”4.27.6″ _module_preset=”default” custom_padding_tablet=”0px||0px||false|false” custom_padding_phone=”0px||0px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row column_structure=”1_2,1_2″ make_equal=”on” module_class=”middle” _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ module_class=”margbtm20″ _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/dr-seban-chirurgien-vasculaire.com\/wp-content\/uploads\/2026\/04\/Maladie-coronique-two.jpg” _builder_version=”4.27.6″ _module_preset=”default” theme_builder_area=”post_content” title_text=”Coronary-disease-two” hover_enabled=”0″ sticky_enabled=”0″][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” header_2_font=”|700|||||||” header_2_font_size=”48px” header_2_line_height=”1.2em” custom_margin_tablet=”||0px||false|false” custom_margin_phone=”||0px||false|false” custom_margin_last_edited=”on|tablet” hover_enabled=”0″ header_2_font_size_tablet=”30px” header_2_font_size_phone=”24px” header_2_font_size_last_edited=”on|tablet” header_2_line_height_tablet=”1.4em” header_2_line_height_phone=”1.5em” header_2_line_height_last_edited=”on|tablet” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]

Intensive medical treatment is essential for all patients, regardless of whether intervention is decided upon. It is based on strict blood pressure control, taking antiplatelet therapy as indicated, high-intensity statin therapy or appropriate lipid-lowering therapy, smoking cessation, physical activity, diabetes management, and correction of other cardiovascular risk factors. <\/p>\n

When stenosis is symptomatic, or when asymptomatic stenosis is deemed high-risk in a specialized setting, revascularization may be considered. The two main techniques are carotid endarterectomy, which involves surgically removing the plaque, and carotid stent angioplasty<\/strong> , which aims to treat the narrowing endovascularly. <\/p>\n

 <\/p>\n

The 2023 European guidelines emphasize that the decision must be individualized according to symptoms, anatomy, age, surgical risk, comorbidities, and the expertise of the surgical team. They also reiterate that the historical 30-day risk thresholds remain at 3% for asymptomatic patients and 6% for symptomatic patients, thus necessitating rigorous selection of indications. <\/p>[\/et_pb_toggle][et_pb_toggle title=”What the CREST-2 study shows” open_toggle_text_color=”#000000″ open_toggle_background_color=”RGBA(255,255,255,0)” closed_toggle_background_color=”RGBA(255,255,255,0)” icon_color=”#000000″ open_icon_color=”#000000″ _builder_version=”4.27.6″ _module_preset=”default” title_text_color=”#000000″ title_level=”h3″ title_font=”|700|||||||” title_line_height=”1.2em” custom_margin=”|0px|||false|false” custom_padding=”|0px|||false|false” hover_enabled=”0″ title_font_size_tablet=”22px” title_font_size_phone=”20px” title_font_size_last_edited=”on|phone” border_width_all=”0px” border_width_bottom=”1px” border_color_bottom=”#000000″ locked=”off” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]
