Are there areas of your skin that have changed color, that look like small bumps, and that sometimes hurt? Or is there a strange spot on your body that your baby was born with, but it seems to be getting bigger? These may be simple things. However, sometimes these can be signs of an abnormal condition called Vascular Malformations , which are abnormalities in the blood vessels, or rather, blood vessels. So, don't worry. Let's talk about this in detail and simply today.
What are vascular malformations? Simply put...
Vascular malformations are abnormalities or changes in the blood vessels in our body. These are often congenital. However, sometimes they become apparent during childhood, adolescence, or even adulthood.
Think of the blood vessel system that runs throughout our bodies as a network of roads. Sometimes, when these roads are built, small imperfections and misconnections can occur. That's what happens here too.
These vascular malformations can occur anywhere on your body, from your head to your toes. Sometimes they appear as a soft tissue mass , pain , swelling , or skin discoloration . Some appear on the face, neck, near the brain, or spinal cord. Others look like birthmarks or red spots.
Very rarely, they can recur after a trauma or other event, or even in adulthood. If they cause pain, interfere with vision, interfere with daily activities, bleed, or cause other problems, these vascular malformations need to be treated.
Where on the body do these occur most often?
The word "vascular" means "related to blood vessels." So this condition can affect any blood vessel in our circulatory system. It can also affect the lymphatic vessels in our lymphatic system.
The types of blood vessels that can be affected are:
- Arteries and arterioles - These are the blood vessels that carry oxygenated blood from the heart to other organs.
- Capillaries - A network of very fine blood vessels.
- Veins and venules - These are what bring used blood from the organs back to the heart.
- Lymphatic channels - These carry lymph fluid in the body.
What are the main types of vascular malformations?
These conditions can sometimes appear as birthmarks on a baby's skin. Or, as mentioned earlier, they can develop anywhere in the body, including the brain and spinal cord. Doctors determine the type based on the type of blood vessel that is affected.
These are some of the most commonly seen types:
- Venous malformation: This is the most common type. As the name suggests, it develops in a vein. Veins are the blood vessels in our body that carry oxygen-poor blood back to the heart. These may look like a blue-colored lump, and may sometimes be painful to touch.
- Arteriovenous malformation (AVM): This is an abnormal fusion of arteries and veins. Normally, arteries end in capillaries, and then veins begin. But in an AVM, blood from arteries flows directly into veins, through an abnormal bundle of channels called a nidus . This AVM condition can affect the brain or spinal cord.
- Capillary telangiectasia: This is a small area of enlargement of the capillaries in the brain. Most of the time, these are not a problem. However, very rarely, they can cause hemorrhage , which is bleeding.
- Cavernous malformations: In this condition, the capillaries in the brain are tightly packed together, forming long "caverns." Blood flows very slowly through these caverns.
- Lymphatic malformations: In this, the lymphatic ducts become enlarged and form fluid-filled cysts. These are most often seen in soft tissues such as the face, neck, and axillary regions.
What is the difference between vascular malformations and hemangiomas?
Both are caused by vascular anomalies. Both can appear as spots, similar to birthmarks. But there are clear differences between the two.
- Hemangiomas: These are noncancerous (benign) vascular tumors. They form when blood vessels clump together under the skin. The type called "strawberry hemangiomas" usually appear after a baby is born. They grow rapidly during the baby's first six months. However, these tumors rarely cause problems and often go away on their own without treatment. If a hemangioma is large, interferes with certain activities, causes pain, or causes other problems, it can be controlled with medication that makes it shrink quickly. Surgery is rarely needed.
- Vascular Malformations: These are present at birth, but may not be apparent until childhood or adulthood. They grow slowly. They can also spread deep into surrounding tissues and structures, causing problems. Vascular malformations often require treatment.
Simply put: Hemangioma is a benign tumor that often goes away on its own. However, vascular malformations are persistent conditions that can grow and cause problems. So it's important to distinguish between the two.
What are slow-flow and fast-flow vascular malformations?
Many vascular malformations fall into the "slow-flow" category. This means that blood moves very slowly through the affected blood vessels. Examples of this are venous, lymphatic, or both (venolymphatic) malformations.
However, an AVM (Arteriovenous malformation) is a "fast-flow" vascular malformation. In this, blood flows from the arteries to the veins at a high speed, usually through an abnormal blood vessel called a nidus . When blood travels this fast in a large AVM, the heart has to work harder. This increases the risk of heart failure .
How common are these?
Vascular malformations are very rare conditions. They occur in about 1% of all births. Of these, venous malformations, the most common type, affect about one in every 5,000 to 10,000 people.
What causes vascular malformations?
Most often, these are caused by an abnormality in the development of blood vessels and/or lymphatic channels while the fetus is growing in the mother's womb (in utero). This means that they are usually congenital .
Less commonly, damage to blood vessels during an injury may go unnoticed and develop into a vascular malformation over time. Venous malformations can also appear for the first time after an accident or due to hormonal changes during puberty or pregnancy .
In a very rare case, some people inherit genetic mutations that increase the risk of developing vascular malformations. Researchers are still learning more about these genetic causes.
Who is at higher risk of developing these?
Some people inherit genetic changes that can increase the risk of vascular malformations. Some of these conditions include:
- Blue rubber bleb nevus syndrome: This causes venous malformations in your intestines and digestive system. It can also cause dark blue, red, or black lesions on your skin.
- CLOVES syndrome (congenital lipomatous overgrowth, vascular malformations, epidermal nevi and spine deformities): This causes AVMs to form in your spinal cord. It can also cause scoliosis ( curvature of the spine), fatty tissue growths, and a dark red rash.
- Hereditary hemorrhagic telangiectasia (also known as Osler-Weber-Rendu syndrome): This causes abnormal tangles, or AVMs, in small capillaries.
- Klippel-Trenaunay syndrome (KTS): This causes reddish-purple birthmarks called "port-wine stains", bone or tissue growths, and malformations involving veins or lymphatic channels.
- Parkes Weber syndrome: This causes AVMs to form in your arms or legs.
If you have genetic conditions like these, it's important to be aware of them.
What are the symptoms of vascular malformations?
Symptoms depend on the type of malformation. A vascular malformation that affects your skin may look like a raised red, blue, purple, brown, or black birthmark . These spots may swell, bleed, or be painful.
If you have an AVM in your brain , you may not have any symptoms until it bleeds. If a brain AVM bleeds, you may experience headaches, seizures, or paralysis on one side of your body .
Venous malformations can cause pain, swelling, blood clotting problems, and organ damage.
How do you identify these? How does a doctor find this?
Because vascular malformations don't always cause symptoms, doctors sometimes discover the condition when they're doing tests for another problem.
Doctors use special imaging tests to look at blood flow and detect vascular malformations. These tests include:
- Ultrasound , also called vascular ultrasound .
- MRI (Magnetic Resonance Imaging) , which also includes a test called MR Angiogram (MRA) .
- CT scan (Computed Tomography scan) , which also includes a test called CT angiogram .
- Angiogram and/or venogram .
- Regular X-rays .
These tests can clearly see the condition of the blood vessels in the area, the way blood flows, and whether there is any abnormal narrowing or dilation.
What is the treatment for this?
The main goal of treatment for vascular malformations is to minimize symptoms and reduce potential complications. Malformations that do not cause any problems may not require treatment and can simply be observed over time.
Treatment depends on the type of blood vessel affected. Often, these treatments involve closing off or surgically removing the affected blood vessel. Many malformations can be treated using minimally invasive techniques . Doctors may use methods such as:
- Sclerotherapy: In this, a special medicine is injected into the affected blood vessel, which causes the blood vessel to shrink and close.
- Catheter embolization: In this procedure, a small tube (catheter) is passed through a blood vessel and the abnormal blood vessel is sealed from the inside.
- Laser treatments: This is used for some skin malformations.
- Radiation therapy (radiosurgery): This is used for some deep, difficult-to-operate malformations.
Sometimes, your doctor may recommend a biopsy , which involves taking a piece of tissue for examination. This can help confirm the diagnosis and/or obtain tissue for genetic testing .
Because vascular malformations are complex and rare conditions, it is best to manage them with a team approach consisting of multiple specialists .
Can these develop again after treatment?
Yes, vascular malformations can recur even after treatment. Therefore, you may need to have regular follow-up visits and tests to detect any reoccurring malformations early.
Is there a way to prevent these from forming?
Vascular malformations are often congenital , meaning there is really no way to prevent them.
However, if someone in your family has a genetic condition that causes vascular malformations, you may want to see a genetic counselor . This specialist can explain the options you have to reduce the risk of passing the condition on to your children.
What complications can occur due to these vascular malformations?
Some malformations do not cause any problems and can only be observed. However, in many cases, they can cause pain and swelling .
Some malformations can cause pain, or muscle, joint, or nerve involvement, which can interfere with exercise, sports, work, or daily activities .
Large, high-flow malformations can eventually lead to heart failure .
Vascular malformations in solid organs such as the liver, kidney, or uterus can cause organ dysfunction and other complications.
Some vascular malformations, such as AVMs in the brain or spinal cord, can reduce the amount of oxygenated blood that reaches the brain. This can lead to life-threatening problems, such as:
- Aneurysms ( weakening of the blood vessel wall and bulging like a balloon)
- Intracranial hemorrhage
- Strokes
What is the future for people with this condition? How does this affect their lives?
Vascular malformations, which look like birthmarks, can affect a person's appearance and self-confidence. This can lead to psychological conditions such as depression and anxiety . However, many of these malformations respond well to treatment.
More serious malformations, such as AVMs in the brain, can be life-threatening if they start to bleed.
But, most importantly, most malformations are treatable and respond well to treatment. Therefore, it is important to seek proper medical advice without panicking.
What should you ask your doctor?
If you have any doubts about this condition, or if you have been diagnosed with it, you can ask your doctor these questions:
- How did I get this vascular malformation? (What is the cause?)
- What type of vascular malformation do I have?
- What is the best treatment for me?
- What are the possible risks or side effects of the treatment?
- Should I be concerned about the symptoms of complications? What are those symptoms?
Ask these questions and gain a clear understanding of your situation.
