Vascular Ehlers-Danlos syndrome (vEDS) is a rare genetic condition that affects the body’s connective tissue, and its symptoms can be severe and life-threatening. The most distinctive signs include easy bruising, thin translucent skin, and characteristic facial features, but the most dangerous symptom is the sudden rupture of arteries, the intestine, or the uterus. Unlike other forms of EDS, the primary danger in vEDS is not joint hypermobility but the risk of internal organ or blood vessel rupture, which requires immediate emergency medical attention.
What Are The Symptoms Of Vascular Ehlers Danlos Syndrome?
The symptoms of vascular Ehlers-Danlos syndrome are primarily related to the fragility of blood vessels and hollow organs. The most serious and defining symptom is the spontaneous rupture of an artery, which can occur without any prior warning or trauma. This can lead to sudden severe pain, often described as a tearing sensation, followed by collapse or shock.
Beyond arterial rupture, other hallmark symptoms include a characteristic facial appearance with a thin nose, thin lips, and prominent eyes. The skin is often translucent, allowing veins to be clearly visible, and it bruises very easily. Unlike classical EDS, joint hypermobility is usually limited to the small joints of the hands and feet.
It is critical to understand that the first symptom of vEDS for many people is a major medical emergency. Because the condition is rare and symptoms can be subtle before a crisis, it is often not diagnosed until after a rupture occurs.
What Does a Vascular Rupture Feel Like?
A ruptured artery or organ causes sudden, severe, and often “tearing” pain. The location of the pain depends on which vessel or organ has ruptured. For example, a rupture in the abdomen may cause intense abdominal or back pain, while a rupture in the chest may cause chest pain that radiates to the back or shoulder.
This is a medical emergency. If you or someone with known vEDS experiences sudden, unexplained severe pain, fainting, or signs of shock—such as rapid heartbeat, pale skin, or shortness of breath—call emergency services immediately. Do not wait to see if the pain subsides.
What Are the First Signs of vEDS in Children?
In children, the earliest signs of vEDS can be subtle but are often present from birth. Babies may be born with a clubfoot or a dislocation of the hip. They may also have a congenital dislocation of the hips or unusual facial features that become more apparent with age.
Easy bruising is often one of the first noticeable symptoms, and it may be mistaken for child abuse. The skin may also be soft, velvety, and translucent. If a child has unexplained bruising combined with other features like a characteristic face or a family history of the condition, a genetic evaluation is warranted.
How Does vEDS Affect the Skin and Joints?
The skin in vEDS is typically thin and translucent, meaning you can often see the veins beneath the surface, particularly on the chest and abdomen. It bruises easily and may take a long time to heal, often leaving characteristic scars that look like cigarette paper—thin, wrinkled, and slightly sunken.
Joint hypermobility is less prominent in vEDS than in other EDS types. When it occurs, it is usually limited to the small joints, such as the fingers and toes. However, tendons and ligaments can also be fragile, leading to ruptures of these structures, which is less common in other forms of EDS.
What Are the Specific Facial Features of vEDS?
Many individuals with vEDS share a set of distinctive facial features, though they can be subtle and may not be present in everyone. These features include a thin, pinched nose; thin lips; a small chin (micrognathia); and large, prominent eyes with a distinctive appearance.
The skin on the face often appears tight and drawn. These features become more noticeable with age. While not every person with vEDS has these features, their presence alongside other symptoms like easy bruising and arterial events is a strong diagnostic clue for a doctor.
What Is the Most Dangerous Complication of vEDS?
The most dangerous complication is the spontaneous rupture of a major artery, such as the aorta. This can happen at any age but is most common in a person’s 20s to 40s. Rupture of the intestine, particularly the colon, is also a serious complication that causes sudden, severe abdominal pain and requires emergency surgery.
For women with vEDS, pregnancy carries significant risks. The uterus and its blood vessels are fragile, and there is a high risk of uterine rupture or severe bleeding during delivery. Because of these high risks, pregnancy in women with vEDS requires specialized, high-risk obstetric care and careful planning.
How Is vEDS Diagnosed?
Diagnosis begins with a thorough clinical evaluation. A doctor will look for the hallmark symptoms: easy bruising, translucent skin, characteristic facial features, and a history of unexplained arterial or intestinal rupture. A family history of the condition is also a major factor.
The diagnosis is confirmed with a genetic test that looks for mutations in the COL3A1 gene. This gene is responsible for producing type III collagen, a key protein that provides strength to blood vessels and organs. This blood test is definitive and can distinguish vEDS from other types of EDS.
Can Symptoms of vEDS Be Managed?
There is no cure for vEDS, but management focuses on preventing complications and acting quickly in an emergency. Medications such as celiprolol, a beta-blocker, have been shown in some studies to reduce the risk of arterial rupture, though this treatment is not universally established for all patients.
People with vEDS are advised to avoid contact sports, heavy lifting, and other activities that could cause trauma. Routine screenings, such as echocardiograms to monitor the aorta, may be recommended. Any surgical procedure carries a high risk of tissue fragility, so surgeons must use special techniques to handle the delicate tissues.
When Should Someone Seek Genetic Testing?
Genetic testing should be considered for anyone who has had an unexplained arterial rupture or intestinal perforation at a young age. It is also recommended for individuals who have multiple features of vEDS, such as easy bruising, thin skin, and a characteristic facial appearance, even without a family history.
If a family member has been diagnosed with vEDS, other relatives should consider genetic counseling and testing. A positive genetic test allows for proactive management and surveillance, which can be lifesaving. A negative test in a symptomatic person does not completely rule out the condition, but it makes it highly unlikely.
Frequently Asked Questions
What is the life expectancy for someone with vascular Ehlers-Danlos syndrome?
The median life expectancy for individuals with vEDS is approximately 48 years, but this varies widely depending on when complications occur. The major cause of death is arterial rupture, which can happen at any age.
Is vascular EDS the same as the hypermobile type of EDS?
No, they are completely different conditions caused by different genetic mutations. Hypermobile EDS primarily affects joints, while vascular EDS is defined by the risk of blood vessel and organ rupture.
Can a person have vascular EDS without knowing it?
Yes, many people are unaware they have vEDS until they experience a major complication like a ruptured artery. The condition can also be present for years with only subtle symptoms like easy bruising that are overlooked.
Is there a prenatal test for vascular EDS?
Yes, prenatal testing is available through amniocentesis or chorionic villus sampling if a specific COL3A1 mutation has been identified in a parent. This testing is typically offered through a genetic counselor.
