Understanding Carotid Artery Examination: Why It Matters for Brain Health
A carotid artery examination is a vital tool for detecting stroke risk by assessing blood flow through key arteries supplying the brain. At the Supreme Vascular and Interventional Clinic in Singapore, we evaluate major vessels like the carotid, vertebral, and subclavian arteries, as well as the Circle of Willis, to identify narrowing or blockages early and provide expert stroke prevention care.
Introduction to Carotid Artery Examination
When it comes to preventing strokes and understanding blood flow to the brain, one of the most important tests a doctor may perform is a carotid artery examination. This non-invasive procedure helps assess blood flow through the major arteries that supply your brain and can identify narrowing, blockages, or abnormalities that may lead to stroke or other neurological issues.
Let’s explore how this examination works - and the critical network of arteries it helps evaluate.
What Are the Carotid Arteries?
The carotid arteries are the main blood vessels that deliver oxygen-rich blood from your heart to your brain. Each side of your neck has a common carotid artery, which splits into:
Internal carotid artery: Supplies blood to the brain, especially the front and middle parts.
External carotid artery: Feeds blood to the face, scalp, and neck.
During a carotid ultrasound, your doctor uses sound waves to check for plaque buildup or narrowing in these arteries - a key step in stroke prevention.
The Circle of Willis: Your Brain’s Backup Plan
Once the internal carotid arteries reach the base of the brain, they contribute to a circular network of arteries known as the Circle of Willis. This ingenious system allows blood to flow across both sides of the brain and between the front and back, so if one part is blocked, other routes can compensate.
The Circle of Willis is formed by:
The internal carotid arteries
The anterior cerebral arteries
The posterior cerebral arteries
Connecting arteries like the anterior and posterior communicating arteries
Other Major Arteries Involved in Brain Circulation
Vertebral Arteries
The vertebral arteries are another pair of crucial vessels. They run up the back of the neck through the spine, joining at the base of the skull to form the basilar artery.
The basilar artery supplies the back part of the brain, including the brainstem and cerebellum. It's vital for functions like breathing, balance, and coordination.
Together with the internal carotid arteries, the vertebral and basilar arteries help form the posterior part of the Circle of Willis.
Subclavian Arteries and Innominate Artery
Before the vertebral arteries reach the brain, they branch off from larger arteries near the heart:
Subclavian arteries: These give rise to the vertebral arteries and also supply blood to the arms and chest.
Innominate artery (brachiocephalic artery): This is the first major branch from the aorta on the right side. It splits into the right subclavian and right common carotid artery.
On the left side, the left common carotid and left subclavian artery come directly off the aortic arch.
Aortic Arch: The Starting Point
The aorta is the body’s main artery, and the aortic arch is the curved section that gives rise to major branches including:
1. Innominate artery (right side)
2. Left common carotid artery
3. Left subclavian artery
These vessels are responsible for delivering blood upward toward the head and arms and ultimately to the brain.
Why Is Carotid Artery Examination Important?
A carotid examination, typically using Doppler ultrasound, can help detect:
Carotid artery stenosis (narrowing)
Plaque buildup
Turbulent blood flow
Increased risk of stroke
By identifying issues early, patients can take preventive steps such as medication, lifestyle changes, or even procedures like carotid endarterectomy or stenting. Before or after your carotid ultrasound or vascular assessment, our Carotid Artery Disease & Stroke Image Library can help you better understand what your specialist is evaluating and how carotid disease develops.
A carotid artery examination is just one part of the overall assessment. Imaging findings are considered alongside your symptoms, medical history, and stroke risk before treatment recommendations are made. Learn how these factors come together in our Carotid Artery Disease Decision-Making Guide.
When Should You Get a Carotid Artery Exam?
Your doctor may recommend a carotid artery exam if you:
Have had a transient ischemic attack (TIA) or stroke symptoms
Have high blood pressure, diabetes, or high cholesterol
Are a smoker
Have a family history of stroke
Hear a carotid bruit (abnormal sound) during a physical exam

Knowing the Dangers of a Brain Aneurysm
Dr. Manish Taneja, our brain aneurysm specialist at Supreme Vascular and Interventional Clinic, specializes in minimally invasive procedures for conditions such as brain aneurysm. We offer specialized care, prompt attention, and access to advanced imaging technology and procedures.
Understand brain aneurysms’ potential dangers and taking the first step towards seeking proper medical consultation. Learn more about the health indicators and afflictions to defuse this silent, dangerous ticking time bomb. Fortunately, there are minimally invasive treatment options to manage this condition effectively.
Understanding Brain Aneurysms
Brain aneurysms, simply put, are weak spots in the walls of blood vessels in your brain. These weak areas can balloon out and potentially rupture, leading to serious complications. While the exact causes are still being studied, factors like high blood pressure, smoking, and family history can increase the risk.
Consult a Seasoned Brain Aneurysm Specialist
Finding the right doctor is key to your journey towards treatment and recovery. Dr. Manish Taneja has treated thousands of patients and treated brain aneurysms ranging from one milimeter to four centimeters. He has treated a range of ages from the young up to the average age for brain aneurysms of around 35 to 60. Unfortunately, no one can predict a brain aneurysm and also the young and fit are at risk. A brain aneurysm rupture can even cause a young to pass away in their sleep. Stay informed about treatment options and receive a recommended course of action with a seasoned brain aneurysm specialist who can give you a clearer picture of what lies ahead.
Walking Time Bombs
With limited data in Singapore, Dr. Manish Taneja estimates that one in 100 people in the general community experience the condition in their lifetime. Brain aneurysms can go unnoticed or undetected – until it is too late. It’s when the brain aneurym ruptures, the results are grim. It’s a less talked about condition and one of the reasons we don’t hear much about it is because brain aneurysm is often overlooked by heart disease, ischemic stroke, or breast cancer.
Knowing risk factors for a brain aneurysm is the first step in early detection and treatment:
- Worst headache in life
- Sudden sensitivity to light
- Sudden stiffness of neck
- Sudden sharp pain behind or above one eye
- Sudden blurred or double vision
- Sudden numbness and tingling in facial area
- Sudden loss of consciousness.
- Sudden confusion or change of mental status.
- Seizure
- Perceived “gun shot” noise or extremely loud “BOOM.”
- Drooping eyelid, nausea and vomiting
It’s important to understand the potential dangers of brain aneurysms. A ruptured aneurysm can cause severe bleeding in the brain, leading to a stroke or even death. Even untreated aneurysms can have long-term effects on your health. That’s why regular follow-up care and monitoring are crucial to managing this condition effectively.

Imagine heart attacks where the blood flow to your heart is blocked. Similarly, a stroke occurs when the blood flow to your brain is interrupted becoming a “brain attack”, affecting a blood vessel and surrounding brain function. When blood supply does not reach a certain part, brain cells begin to die. Different types of stroke include ischemic strokes or a mini stroke, a TIA (transient ischemic attack). Common risk factors include high blood pressure, which increases strain on the blood vessel and raises the likelihood of a stroke. Symptoms can vary, but may include difficulty in speaking and other changes depending on how blood flow is affected. Understanding risk factors and acting early can make a difference. It’s important to work closely with a specialist to monitor your health and reduce stroke risk.
