Welcome back, everyone! Continuing our theme of exploring genetic syndromes that can cause heritable aortic disease, today we will be diving into Ehlers-Danlos syndrome (EDS). EDS is a group of inherited conditions that affect the body's connective tissue. While many people associate EDS with flexible joints or stretchy skin, some forms of the condition can also affect the heart and blood vessels, including the aorta. Understanding this connection is an important step in preventing complications and protecting long-term health.
What is Ehlers-Danlos syndrome?
Connective tissue acts as the body's building material, providing strength and support to the skin, joints, blood vessels, and many internal organs. In people with EDS, genetic changes affect the body's ability to produce healthy connective tissue. As a result, tissues may be more fragile or less able to withstand everyday stress.
There are several types of EDS, and each affects the body differently. Most types primarily involve the joints and skin, but one subtype, vascular Ehlers-Danlos syndrome (vEDS), can have serious effects on the blood vessels.
How does EDS affect the aorta?
In vascular Ehlers-Danlos syndrome, the walls of arteries are more fragile than normal. This can increase the risk of:
Aortic aneurysms, where part of the aorta becomes enlarged,
Aortic dissections, where a tear develops in the wall of the aorta, and
Tears or ruptures in other arteries throughout the body
Although vascular EDS is uncommon, recognizing it early is important because blood vessel complications can occur at a younger age than in the general population.
How is EDS diagnosed?
Doctors may suspect EDS based on a person's medical history, family history, and physical examination. Features such as easy bruising, thin or translucent skin, unusually flexible joints, or a family history of arterial rupture may raise concern.
The diagnosis of vascular EDS is typically confirmed through genetic testing, which can identify changes in the COL3A1 gene responsible for the condition.
How is EDS managed?
There is currently no cure for vascular EDS, but careful monitoring and preventive care can significantly reduce the risk of complications.
Management often includes:
Regular imaging of the aorta and other major arteries
Careful control of blood pressure
Avoiding activities that place excessive strain on the blood vessels
Routine follow-up with specialists familiar with inherited aortic disease
If an aneurysm becomes large enough or other complications develop, surgery may be recommended. Because tissues are more fragile in patients with vascular EDS, these operations are often performed at specialized centers with experience treating complex aortic disease.
Why family history matters
Because Ehlers-Danlos syndrome is inherited, a diagnosis in one family member may have implications for others. If multiple relatives have experienced aneurysms, arterial dissections, or sudden vascular events at a young age, discussing genetic evaluation with your healthcare provider may be appropriate.
Identifying the condition early allows patients and families to receive appropriate screening, monitoring, and treatment before complications occur.
Bottom line
Most people with Ehlers-Danlos syndrome will never develop serious aortic disease, but those with vascular Ehlers-Danlos syndrome have an increased risk of aneurysms and dissections because of the underlying weakness of their vascular connective tissue.
With regular monitoring, good blood pressure control, and care from an experienced multidisciplinary team, many patients can successfully manage the condition and reduce their risk of life-threatening complications.
That's all for this one, folks. Keep thinking aorta!
