Carotid stenosis is the narrowing of the carotid arteries in the neck, which supply oxygen-rich blood to the brain. This narrowing is primarily caused by atherosclerosis, the buildup of fatty deposits, cholesterol, and plaque inside arterial walls. Over time, the condition significantly increases the risk of ischemic stroke or transient ischemic attacks (TIAs). Symptoms may include sudden weakness, speech difficulties, vision problems, or dizziness, though many patients remain asymptomatic until complications arise. Diagnosis involves ultrasound, CT angiography, or MRI. Treatment options include lifestyle changes, medications, stenting, or carotid endarterectomy. Early detection and management are vital for reducing stroke risk.
Carotid stenosis develops from plaque buildup and vessel narrowing, influenced by high blood pressure, smoking, and cholesterol. These combined risk factors and causes elevate stroke risk significantly without timely treatment.
Early diagnosis and treatment significantly lower the risk of ischemic stroke, protecting brain health and patient survival.
Treatments like stenting or surgery restore blood flow, ensuring better oxygen supply to the brain and body.
Managing carotid stenosis reduces long-term complications, enabling patients to live healthier, more active, and independent lives.
Numbness or weakness in face, arms, or legs, often on one side, may indicate reduced brain blood flow.
Difficulty speaking, slurred words, or trouble understanding others may arise during carotid-related transient ischemic attacks.
Blurred or partial vision loss in one or both eyes can signal narrowing of carotid arteries.
