Which are the symptoms of Arterial Tortuosity Syndrome?

Arterial Tortuosity Syndrome is a rare connective tissue disorder characterized primarily by the elongation and twisting (tortuosity) of the major arteries, including the aorta and pulmonary arteries. Symptoms often present in childhood and can include distinctive craniofacial features, skin hyperextensibility, and an increased risk of serious cardiovascular complications such as aneurysms or dissections.

What are the characteristic symptoms of Arterial Tortuosity Syndrome?

The clinical presentation of Arterial Tortuosity Syndrome is systemic, affecting both the vascular and skeletal systems. Beyond the characteristic arterial elongation, patients often exhibit specific physical traits. Common clinical manifestations include:

• Vascular abnormalities: Tortuosity, stenosis, and aneurysm formation in the large and medium-sized arteries.


• Craniofacial features: A long, narrow face, micrognathia (small jaw), a high-arched palate, and down-slanting palpebral fissures.


• Dermatological signs: Skin that is soft, hyperextensible, and bruises easily, often with translucent qualities.


• Skeletal involvement: Arachnodactyly (long, slender fingers), joint hypermobility, and pectus excavatum or carinatum.

How does Arterial Tortuosity Syndrome affect quality of life?

The impact of Arterial Tortuosity Syndrome on daily life varies significantly. While many individuals live active lives, the psychological burden of monitoring a vascular condition is substantial. Physical limitations may arise from joint instability or fatigue, but the primary concern remains the risk of cardiovascular events, which necessitates lifelong medical surveillance and potential activity restrictions to prevent arterial stress.

When should you seek immediate medical attention?

Because Arterial Tortuosity Syndrome involves the large arteries, families must be vigilant. Seek emergency care if a patient experiences sudden, severe chest or abdominal pain, unexplained shortness of breath, sudden neurological deficits, or fainting spells, as these could indicate an arterial dissection or rupture.

How does the condition progress over time?

Arterial Tortuosity Syndrome is a progressive condition. While the craniofacial features remain constant, the severity of vascular tortuosity can increase during childhood. With 7 members in our DiseaseMaps.org community sharing their experiences, we see that proactive management is the most effective way to stabilize the condition and improve long-term outcomes.
