What is Carotid Angiography?
Carotid Angiography is a diagnostic procedure that visualises the carotid arteries. These are major blood vessels in the neck that supply blood to the brain. The procedure involves injecting a contrast dye into the bloodstream. This helps in capturing detailed images of the carotid arteries using X-ray imaging. It helps in assessing the blood flow and identifying any blockages or abnormalities.
This procedure is essential for detecting conditions like carotid artery stenosis (narrowing of the arteries) or aneurysms. If left untreated, these conditions can lead to serious complications such as strokes. Carotid Angiography helps in planning treatments like carotid endarterectomy or carotid artery stenting. These modern surgical approaches aim to restore proper blood flow and prevent potential risks.

Everything you need to know about the procedure, preparation, and recovery
Carotid Angiography Procedure Indications
Doctors recommend carotid angiography to evaluate blood flow in the carotid arteries. This procedure helps identify blockages or abnormalities that may lead to stroke or other complications.
Transient Ischemic Attacks (TIAs)
Patients may experience sudden weakness, numbness, or difficulty speaking. Doctors find temporary disruptions in blood flow to the brain. When symptoms persist or recur despite medication, angiography is advised.
Stroke Symptoms
Sudden severe headache, vision changes, or loss of balance can occur. Imaging may show reduced blood flow in the carotid arteries. If initial treatments do not improve symptoms, angiography is recommended.
Carotid Bruit
A whooshing sound heard over the carotid artery during a physical exam suggests turbulent blood flow. Ultrasound may reveal narrowing of the artery. Angiography is considered when non-invasive tests are inconclusive.
Severe Carotid Stenosis
Patients often have no symptoms, but imaging shows significant narrowing of the carotid artery. When lifestyle changes and medications fail to reduce risk, angiography is performed for further assessment.
Follow-up After Carotid Surgery
Patients may experience recurrent symptoms like dizziness or weakness. Post-surgical imaging may show changes in the artery. Angiography helps evaluate the success of previous interventions.
How to Prepare for Carotid Angiography?
Proper preparation is crucial for carotid angiography to ensure accurate results and minimise risks. Following these steps can help you be ready for the procedure.
- Medication Adjustment: Stop NSAIDs, anticoagulants, and herbal supplements as advised by your doctor.
- Fasting: Do not eat or drink anything for 6-8 hours before the procedure to prepare for anaesthesia.
- Medical History: Bring a list of all medications you are taking, including dosages, to inform the medical team.
- Allergy Information: Inform your doctor about any allergies, especially to contrast dye or iodine.
- Clothing: Wear loose, comfortable clothing on the day of the procedure for ease of movement.
- Transportation: Arrange for someone to drive you home after the procedure as you may feel drowsy.
- Pre-Procedure Tests: Complete any blood tests or imaging studies as instructed by your healthcare provider.
- Personal Items: Leave valuables at home and bring only essentials to the hospital.
Carotid Angiography procedure (Step-by-Step)
Overview: Carotid angiography is performed by interventional radiology specialists. The procedure typically lasts 1-2 hours and is usually done under local anaesthesia.
- Preparation: The patient is positioned on the examination table. The groin area is cleaned and sterilised. Local anaesthesia is administered to numb the area.
- Accessing the Artery: A small incision, about 1-2 cm, is made in the groin. A catheter is inserted into the femoral artery using a guide wire.
- Catheter Navigation: The catheter is carefully guided through the blood vessels to reach the carotid arteries in the neck. The patient may feel slight pressure but should not experience pain.
- Contrast Injection: A contrast dye is injected through the catheter. This may cause a warm sensation. The dye helps to highlight the carotid arteries on X-ray images.
- Imaging: X-ray images are taken to assess the blood flow and detect any blockages or abnormalities in the carotid arteries.
- Catheter Removal: The catheter is gently withdrawn. Pressure is applied to the incision site to prevent bleeding.
- Recovery: The patient is monitored for a few hours. Instructions for home care and activity restrictions are provided.
