How common is arterial thoracic outlet syndrome?
Background: Clinical manifestations of thoracic outlet syndrome (TOS) differ depending on the compromised anatomic structure. Arterial TOS is the least common (1-5% of all cases of TOS), yet the most threatening, due to the risk of limb loss.
How do you fix arterial TOS?
Surgery is usually recommended for arterial TOS. This may involve removing both the scalene muscles in the neck, the cervical rib if present and the first rib. Other treatments include: Medication: blood thinners to treat clots.
How many types of TOS are there?
To clarify, each of the three types of TOS is defined by the vital structure that is compressed in the thoracic outlet: Subclavian Artery: Arterial TOS. Subclavian Vein: Venous TOS. Brachial Plexus: Neurogenic TOS.Jun 8, 2021
What is the most common type of TOS?
Neurogenic TOS is the most common form of the disorder (95 percent of people with TOS have this form of the disorder) and generally affects middle-aged women. Recent studies have shown that, in general, TOS is more common in women than men, particularly among those with poor muscular development, poor posture or both.
What are the two types of TOS?
- Neurogenic TOS occurs when the nerves leading from the neck to the arm (the brachial plexus) is compressed.
- Venous TOS occurs when a vein is compressed, leading to upper body thrombosis.
- Arterial TOS occurs when an artery is compressed.
How do you diagnose TOS?
- Ultrasound. An ultrasound uses sound waves to create images of your body.
- X-ray.
- Computerized tomography (CT) scan.
- Magnetic resonance imaging (MRI).
- Arteriography and venography.
- Electromyography (EMG).
Is arterial thoracic outlet syndrome serious?
Arterial thoracic outlet syndrome is a rare cause of shoulder pain due to compression of the subclavian or axillary arteryaxillary arteryIn human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.https://en.wikipedia.org › wiki › Axillary_arteryAxillary artery - Wikipedia within the thoracic outlet.

How is arterial TOS diagnosed?
The diagnosis is suspected by clinical findings and confirmed by imaging studies, such as Duplex ultrasound imaging and vascular laboratory studies, contrast-enhanced CT or MR angiography, or traditional catheter-based arteriography.
Does thoracic outlet syndrome go away?
Can thoracic outlet syndrome improve on its own? No. For people who have mild TOS, lifestyle changes may be enough to make the symptoms go away. But more serious TOS should be treated by a doctor as soon as possible.
Is arterial TOS serious?

Five percent of cases are venous. Arterial TOS occurs when an artery is compressed. Only about 1 percent of cases are arterial.
