What are the best treatments for Arterial Tortuosity Syndrome?

Arterial Tortuosity Syndrome (ATS) is a rare connective tissue disorder primarily managed through lifelong cardiovascular surveillance and blood pressure regulation to prevent life-threatening complications like aneurysms or dissections. Currently, there is no curative therapy for Arterial Tortuosity Syndrome, so clinical management focuses on the proactive monitoring of the aorta and major arteries alongside surgical intervention when structural risks become critical.

How is Arterial Tortuosity Syndrome managed medically?

Treatment for Arterial Tortuosity Syndrome is highly individualized based on the specific vascular involvement and the patient's hemodynamic profile. Physicians often prescribe medications to reduce mechanical stress on the arterial walls. Common pharmacological interventions include:

• Beta-blockers (e.g., atenolol, propranolol) to decrease heart rate and systemic blood pressure.


• Angiotensin II receptor blockers (e.g., losartan) to modulate the TGF-beta signaling pathway, which is often dysregulated in Arterial Tortuosity Syndrome.

What surgical and non-pharmacological interventions are used?

Because the hallmark of Arterial Tortuosity Syndrome is the elongation and twisting of arteries, surgical repair is reserved for high-risk anatomy, such as severe aortic root dilation or stenotic lesions. Because tissue in Arterial Tortuosity Syndrome is fragile, surgeons must carefully weigh the risks of intervention against the natural progression of the disease. Physical therapy and occupational therapy are often recommended to manage joint hypermobility and muscle weakness, which are common non-vascular features of the condition.

Which specialists should be on the care team?

Managing Arterial Tortuosity Syndrome requires a multidisciplinary team to address the systemic nature of the condition. Your care team should ideally include:

• Cardiologists or Cardiovascular Surgeons: To perform regular echocardiograms and CT/MRI angiography.


• Clinical Geneticists: To provide counseling regarding the autosomal recessive inheritance pattern.


• Physical Therapists: To assist with joint stability and musculoskeletal health.


• Genetic Counselors: To support family planning and testing for relatives.
