Do you know about these important veins in your neck? (Jugular Veins) Let's talk about this!

Have you ever wondered about the network of veins that run from our head to our chest, and that serve a very important function? Those are the jugular veins. These are like the main roads that carry used blood from our head back to our heart. So today we will talk about these jugular veins, their importance, the problems that can occur with them, and how to keep them healthy.

What are the jugular veins? Where are they located?

Simply put, the jugular vein is a major blood vessel system that runs from our head to our upper chest. There are usually three pairs of these, for a total of six veins. Each of these collects blood from different parts of the head and carries it back to the heart. Now let's look at what these types of veins are and where they are located.

• External jugular veins: These are the veins that carry blood from the outside of our skull. Think of them as veins called the occipital veins at the back of our head and run down each side of our spine . The word "external" means that they are located between the large muscle groups of the neck and the skin, which means they are located a little closer to the skin.
• Internal jugular veins: These are slightly larger than the external veins mentioned earlier. These veins help bring blood from the brain back to the chest. They start inside our skull . Then, like the external veins, they run down the spine on both sides. But the main difference is that they are located under the large muscles of the neck, which means they are a little deeper inside the body. The internal jugular vein on the right side is slightly larger than the left, so doctors use it more often to insert an IV line.
• Anterior jugular veins: These are the smallest of the jugular veins. Both are located in the front of the neck, on either side of our windpipe.

What benefit do these veins have for our bodies?

Did you know that our brain needs oxygen? Just think, even though the average human brain weighs about 1.4 kilograms, only 15% to 20% of the blood pumped by our heart goes to the brain! Also, other parts of the head, such as our face, scalp, and ears, also need good blood circulation for various reasons. So, after this blood has given oxygen to the brain and other parts of the head, that blood needs to go back to the heart to make way for new blood. That's what these jugular veins do. It is because of these veins that blood flows properly and continuously to the brain and other parts of the head.

Very important, right? Just like the main roads in a city, without these veins, blood flow would be disrupted.

How are the jugular veins connected to each other?

After this jugular vein passes through the neck, it connects to another major vein. Let's see how:

• External: The external jugular vein is connected to the subclavian vein. The subclavian vein means "under the clavicle." The clavicle is the part of our collarbones.
• Internal Vein: The internal jugular vein also joins the subclavian vein under our collarbone. Once joined, they become the ``brachiocephalic vein.'' The name means ``relating to the arm and head.''
• Anterior veins: These join the external jugular veins.

Finally, these two brachiocephalic veins join just below where our neck meets our chest to form one large vein. It is called the ``superior vena cava.'' This is one of the largest veins in our body. All the blood from the upper parts of our body is carried back to the heart through this vein.

What are the common diseases that can affect this nervous system?

Although there are not many diseases that directly affect the jugular vein, some conditions can affect it.

• Aneurysm : This is a weakness in the wall of a blood vessel, causing part of the vessel to bulge outward like a balloon. If this bulge ruptures or ruptures, severe bleeding can occur and can be life-threatening.
• Diabetes : Although diabetes does not directly affect the jugular vein, the internal jugular vein is a common place to insert an IV line or cannula (a small tube used to give medication). This can happen especially if someone needs to have dialysis ( blood dialysis ).
• Stenosis: This is the narrowing or narrowing of a blood vessel. This can be caused by injuries , scars after surgery, or various diseases.
• Thrombosis: This is when a blood clot forms inside a vein, or forms somewhere else and gets stuck in the vein. If the clot is large, it can completely block the flow of blood through the vein. Sometimes, blood clots that form after surgery on the throat or neck, or after an infection (such as `Lemierre's syndrome`) can be dangerous because the infection can spread throughout the body and cause a serious, life-threatening condition called `sepsis`.

What are the symptoms of a problem with the jugular veins?

If there is a problem with your jugular vein, you may experience symptoms related to it or in areas related to it, such as the head.

• Distension: When the pressure inside a vein increases, it becomes bulging outward. This bulging appearance can sometimes be a sign of serious heart conditions such as heart failure (not a heart attack, but a malfunction of the heart), cardiac tamponade (fluid buildup around the heart), or coronary artery disease (coronary artery disease).
• Ear problems: Increased pressure in the arteries can also affect your ears. You may experience dizziness, tinnitus (pronounced "tin-ee-tus" or "tin-ita-as," which is simply a constant ringing in the ears ), or hearing loss. A specific example of this is pulsatile tinnitus. This means you hear your own heartbeat in your ears, like a "whoosh" or "whoosh" sound.
• Eye problems: Increased pressure caused by restricted blood flow through the jugular vein can cause blurred vision, double vision, or eye swelling.
• Pain: You may experience neck pain, discomfort, or a headache.
• Insomnia problems: Changes in the way blood flows out of the brain can also affect your sleep.

How do you check the health of these veins?

The most common tests to check the condition of the jugular veins are a physical examination and various imaging tests.

• Physical examination: This involves placing your upper body in a specific position and a doctor checking for swelling or pressure changes in the jugular veins. This may involve turning your head to one side, breathing in and out, or the doctor may press on certain areas of your upper chest or abdomen to check for pressure changes in the jugular veins.
• Vascular ultrasound: This uses high-frequency sound waves to "look" at your jugular vein. Much like bats use sound waves to fly without hitting obstacles.
• CT scan and angiography: A CT scan (Computerized tomography) is a procedure that uses X-rays and computer technology to create a three-dimensional (3D) picture of the inside of your body. A CT angiogram uses a dye called contrast, which is injected into your blood vessels. This contrast shows up well on a CT scan, so it can help find areas where blood is not flowing properly.
• MRI:An MRI (Magnetic Resonance Imaging) test uses a very powerful magnet and computer technology to create images of the inside of the body. This is very useful for creating very detailed images that can differentiate between things like muscles, blood vessels, nerves, and bones.

What are the treatments for Jugular Veins?

Here are some common treatments that are given for conditions that affect the jugular vein, or that use the jugular vein to treat other conditions:

• Antibiotics: These may be given if there is an infection affecting the jugular veins.
• Blood thinners: These are most commonly prescribed for blood clotting problems such as thrombosis.
• IV lines: Examples include `central line` and `PICC (Peripherally Inserted Central Catheter) line`.
• Surgery: This can help with blocked or damaged jugular veins. In some cases, a surgeon may remove a jugular vein and use it to create a 'bypass' around a blocked blood vessel in your heart. Depending on which jugular vein is involved, you may be able to live without long-term effects after removing or occluding one.
• Vena cava filters: These are filters that a doctor inserts through a jugular vein and sends to one side of your ``superior vena cava.`` Once there, they catch blood clots before they can travel to your heart and lungs. This helps prevent life-threatening conditions like ``pulmonary embolism.``

How do I keep my jugular veins healthy? (Keep this in mind!)

Here are some of the best things you can do to keep your jugular veins healthy:

• Take care of your heart health. Diseases of the circulatory system that affect your heart can also affect major blood vessels, including the jugular vein. Maintaining a healthy weight, eating a healthy diet, and being physically active are important for this.
• Take care of your neck. Your jugular vein, especially the external jugular vein, is prone to injury and damage. Be careful and wear the necessary safety gear when playing sports (especially ice hockey) or working with electrical equipment.
• Pay attention to changes in your body. If you start to experience symptoms like neck pain or swelling, or if you have any symptoms related to your vision or brain, talk to a doctor. It's a must-do, especially if those symptoms start to affect your daily activities.
• Keep it clean.If you have an IV in your jugular vein, keep the area around the IV line or port clean. It is also important to follow your doctor's instructions about how and when to turn your neck or head.

The jugular vein is a very important part of our circulatory system, especially because it affects blood flow to your brain. Although there are not many diseases that directly affect it, the jugular vein often plays an important role in diagnosing and treating other diseases. So, if you have any doubts about problems related to the jugular vein, talk to a doctor. They will be able to answer your questions or refer you to a specialist who can help you further.
