Aberrant Subclavian Artery: Causes, Symptoms, and Treatment

What kind of doctor treats Aberrant Subclavian Artery?
A vascular surgeon usually treats this condition and decides whether the artery needs surgery or just monitoring. A person may first see a family doctor or a stomach and throat specialist before a vascular surgeon steps in. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
An aberrant subclavian artery is a blood vessel that grows in an unusual place. The subclavian arteries carry blood from the heart to the arms. In people with this condition, the right artery starts lower on the aorta than usual and passes behind the esophagus. Doctors sometimes call this an arteria lusoria. Many people have it and never know, because it often causes no trouble.
Symptoms
Many people with an aberrant subclavian artery have no symptoms. When symptoms do happen, the unusual vessel can press on the esophagus and make food feel like it is sticking, a problem called dysphagia. In rare cases, it can press on the windpipe and cause breathing problems.
Causes and who gets it
This condition is present at birth, forming while the baby's arteries develop in the womb. It is one of the more common unusual artery patterns and is often discovered by accident on a chest scan done for another reason.
How doctors diagnose it
Doctors often find this artery by chance on imaging tests done for something else. A CT scan or MRI can show the vessel clearly. A barium swallow test can show it pressing on the esophagus. If treatment is planned, doctors may order an angiogram to map the blood vessels.
Treatment
Treatment depends on symptoms. If the artery causes no problems, doctors usually leave it alone and keep an eye on it. If it causes trouble swallowing, surgery can move the vessel or release the pressure on the esophagus, often with small cuts and special tools.
When to see a doctor
Talk to a doctor if food regularly feels like it is sticking when you swallow. Seek care promptly if you have trouble breathing along with swallowing problems. Tests are the only way to know what is causing these symptoms.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. They often have longer visits, can order imaging tests, and can manage the condition if no treatment is needed, or refer you to a vascular surgeon if surgery might help.
Common questions
Is an aberrant subclavian artery dangerous?
For most people, no. It usually causes no symptoms and needs no treatment. In some people it presses on the esophagus or windpipe. In rare cases it can lead to other vessel problems that a doctor can monitor.
Can it go away on its own?
No. The artery is built that way from birth, so it does not change position over time. Symptoms, however, can sometimes improve with treatment.
Does it always need surgery?
No. Most people never need surgery. Doctors usually recommend an operation only when the artery causes ongoing trouble with swallowing or breathing.
Can I exercise normally with this condition?
Most people with no symptoms can be active without any restrictions. If you have symptoms or have been told you have this artery pattern, ask your doctor what is safe for you.
