What is DSA Carotid Stenting (ICA)?

Comprehensive Guide to DSA Carotid Stenting (ICA)

img

DSA Carotid Stenting (ICA) stands for:

  • DSA: Digital Subtraction Angiography – an advanced imaging technique used to visualize blood vessels by removing (subtracting) the background structures from the image.
  • Carotid Stenting: A minimally invasive procedure used to open blocked carotid arteries, which supply blood to the brain.
  • ICA: Internal Carotid Artery – the main artery that delivers blood to the brain.

Carotid stenting is performed to treat carotid artery stenosis, a condition where the carotid arteries become narrowed or blocked due to plaque buildup (atherosclerosis). The procedure helps:

  • Restore proper blood flow to the brain.
  • Prevent stroke in patients with significant carotid artery narrowing.
  • Minimize the risk of future cardiovascular events.

Types of DSA Carotid Stenting (ICA)

Carotid stenting procedures are categorized based on:

img

Used for newly diagnosed carotid artery stenosis.

Stent placement directly opens the artery.

Common for patients with moderate to severe blockage.

img

Performed in patients with recurrent narrowing of the carotid artery after a previous surgery or stenting.

Stent-in-stent technique may be used.

Reduces the risk of recurrent stroke or embolism.

img

Balloon is inflated to widen the narrowed artery before placing the stent.

Ensures the artery remains open and stable.

Suitable for complex or severely blocked arteries.

img

Uses a stent coated with medication to prevent scar tissue formation.

Reduces the risk of re-narrowing.

Ideal for patients prone to restenosis.

Symptoms Indicating the Need for DSA Carotid Stenting

Carotid artery stenosis may be asymptomatic in the early stages. As the blockage worsens, symptoms may include:

img
Transient Ischemic Attack (TIA)

Mini-stroke lasting a few minutes to hours.

Temporary symptoms such as:

Sudden weakness or numbness on one side of the body.

Slurred speech or difficulty speaking.

Temporary vision loss in one eye.

Dizziness or balance issues.

img
Stroke Symptoms

Sudden and severe neurological deficits.

Paralysis or weakness on one side of the body.

Confusion, speech difficulty, or cognitive issues.

Vision problems or complete loss of vision.

img
Carotid Bruit

Abnormal sound (bruit) heard through a stethoscope.

Indicates turbulent blood flow due to arterial narrowing.

img
Dizziness or Fainting

Caused by reduced blood flow to the brain.

May occur with mild exertion.

Risk Factors for DSA Carotid Stenting (ICA)

Certain factors increase the likelihood of carotid artery disease and the need for stenting:

img

Causes Leading to DSA Carotid Stenting

DSA Carotid Stenting is required when narrowed carotid arteries restrict blood flow. Common causes include:

Atherosclerosis

Cholesterol and fat deposits form plaques.

Gradually narrow the carotid arteries.

Arterial Injury or Trauma

Neck injuries can damage the carotid artery.

May lead to narrowing or blockage.

Fibromuscular Dysplasia

Abnormal cell growth in artery walls.

Causes narrowing or irregularity of the artery.

Post-Surgical Restenosis

After a carotid endarterectomy (CEA), restenosis can occur.

May require DSA carotid stenting.

How to Prevent the Need for DSA Carotid Stenting?

img
Healthy Diet

Low-fat, high-fiber diet reduces cholesterol.

Include fruits, vegetables, and whole grains.

img
Regular Exercise

150 minutes of moderate-intensity exercise weekly.

Helps control weight and blood pressure.

img
Quit Smoking

Reduces the risk of carotid artery disease.

Improves vascular health.

img
Medication Management

Statins and antihypertensive drugs control cholesterol and blood pressure.

Reduces the risk of plaque formation.

img
Manage Diabetes

Maintain blood sugar levels within target range.

Reduces damage to blood vessels.

Treatment of DSA Carotid Stenting (ICA)

Medications

Antiplatelet therapy (aspirin, clopidogrel) to prevent clotting.

Statins to lower cholesterol and reduce plaque formation.

Blood pressure control with ACE inhibitors or beta-blockers.

Endovascular Intervention

DSA-guided stent placement to open the narrowed artery.

Improves blood flow and reduces stroke risk.

Procedures Available for DSA Carotid Stenting (ICA)

img

DSA maps the arteries and identifies blockages.

A catheter is inserted into the femoral artery and guided to the carotid artery.

Balloon angioplasty expands the artery.

A stent is placed to keep the artery open.

Duration: 1–2 hours.

img

Prevents debris from dislodging during the procedure.

Reduces the risk of stroke.

img

Antiplatelet medications to prevent clots.

Lifestyle modifications to prevent restenosis.

img

Hospital Stay: 1–2 days.

Full Recovery: 1–2 weeks.

Post-Op Instructions:

  • Avoid heavy lifting for at least 2 weeks.
  • Take prescribed blood thinners.
  • Regular follow-ups with Doppler ultrasound.
