Thromboembolic Internal Carotid Artery Stroke

A thromboembolic internal carotid artery stroke, also known as a TICAS, is a type of stroke that happens when a blood clot (thrombus) or debris travels through your bloodstream and blocks a vital blood vessel in your brain. This blockage can result in severe brain damage and various symptoms. In this article, we’ll break down everything you need to know about TICAS, from its causes and symptoms to diagnosis, treatment options, and more, in simple, easy-to-understand language.

Types of Thromboembolic Internal Carotid Artery Stroke:

There are two main types of TICAS:

  • a. Ischemic Stroke: Occurs when a clot or debris blocks an artery, reducing blood flow to a specific part of the brain.
  • b. Embolic Stroke: Happens when a clot or debris travels from another part of the body, like the heart, to the brain and lodges in a blood vessel, causing a blockage.

 Common Causes of TICAS:

  1. High Blood Pressure: Uncontrolled hypertension can damage blood vessels, increasing the risk of clots.
  2. Smoking: Smoking damages blood vessels and promotes clot formation.
  3. Diabetes: Poorly managed diabetes can lead to vascular problems.
  4. High Cholesterol: Elevated cholesterol levels can contribute to artery narrowing.
  5. Atrial Fibrillation: An irregular heart rhythm can cause blood clots.
  6. Obesity: Being overweight increases the likelihood of hypertension and diabetes.
  7. Family History: A family history of strokes may indicate genetic factors.
  8. Age: The risk of TICAS increases with age.
  9. Gender: Men are more prone to TICAS than women.
  10. Sedentary Lifestyle: Lack of physical activity can lead to risk factors like obesity.
  11. Excessive Alcohol Consumption: Heavy drinking can raise blood pressure.
  12. Drug Abuse: Illicit drug use can contribute to clot formation.
  13. Stress: Chronic stress may negatively affect cardiovascular health.
  14. Migraines: Some types of migraines are associated with stroke risk.
  15. Sleep Apnea: This condition disrupts oxygen supply and can contribute to TICAS.
  16. Heart Disease: Conditions like heart attacks can lead to clots.
  17. Blood Disorders: Conditions like sickle cell anemia increase stroke risk.
  18. Birth Control Pills: Certain contraceptives may raise the risk of clot formation.
  19. Hormone Replacement Therapy: Postmenopausal women on HRT may have an increased risk.
  20. Prior Strokes: If you’ve had a stroke before, you’re at a higher risk for another.

 Common Symptoms of TICAS:

  1. Sudden, severe headache.
  2. Weakness or numbness on one side of the body.
  3. Trouble speaking or understanding speech.
  4. Dizziness and loss of balance.
  5. Blurred or double vision.

  9. Doppler Ultrasound: Evaluates blood flow in the brain.
  10. Transcranial Doppler: Measures blood flow velocity in brain arteries.
  11. EEG (Electroencephalogram): Records brain’s electrical activity.
  12. Holter Monitor: Monitors heart activity for an extended period.
  13. Blood Pressure Monitoring: Helps assess hypertension.
  14. Carotid Angiography: Provides detailed images of carotid arteries.
  15. Brain Tissue Biopsy: Rarely performed to diagnose rare conditions.
  16. Carotid Stenting: Invasive procedure to clear carotid artery blockages.
  17. Blood Clotting Tests: Assess blood’s clotting ability.
  18. Brain Perfusion Scan: Measures blood flow to brain tissues.
  19. Ophthalmic Examination: Checks eye blood vessels for clots.
