Thoracic Outlet Syndrome

Acute

What is Thoracic Outlet Syndrome?

Thoracic outlet syndrome (TOS) is a family of conditions in which either the blood vessels or nerves are compressed, resulting in nonspecific symptoms such as numbness, tingling, and weakness in the affected area. Imaging can confirm the origin of the condition, but it is not necessary to diagnose TOS.

  • Pain or weakness in the shoulder and arm.
  • Tingling or discomfort in the fingers.
  • Arm that tires quickly.
  • Atrophy — shrinking and weakness — of the pad of the thumb, the muscle of the palm that leads to the thumb; this is quite rare.
  • Numbness and tingling of the fingers
  • Swelling
  • Cold hands
  • Pain in the neck and shoulder
  • Pale discoloration
  • Hand and arm pain
  • Numbness
  • Weak grip
  • Weakness of the neck or arm

Repeated overhead motions: People who take up swimming, baseball or painting, or who work as hairstylists, auto mechanics or other jobs that require raised arms may develop thoracic outlet syndrome. Weight gain: As with extra muscle mass, extra fat in the neck may compress nerves or subclavian vessels.

Risk Factors for Thoracic Outlet Syndrome: Trauma from a car accident (the symptoms can often be delayed) Repetitive injuries (related to sports or job activities) Anatomical defects (such as having an extra rib, usually a cervical rib).

If you're at risk of thoracic outlet compression, avoid repetitive movements and lifting heavy objects. If you're overweight, losing weight may help you prevent or relieve symptoms of thoracic outlet syndrome.

How is it diagnosed?

Treatment for Venous Thoracic Outlet SyndromeSurgery is usually recommended for venous TOS. This may involve removing both the scalene and subclavius muscles and first rib. The vein itself must also be treated. Blood clots often form around the damaged inner surface of the compressed vein.

How is it treated?

Treatment for acute myeloid leukemia is vital. It varies with the patient and stage of the disease. Treatment options include

The surgeon cuts and removes the extra rib and closes the incision with stitches. Scalene muscles may also be removed. Surgery takes about two hours to complete and requires a one- to three-day stay in the hospital. Recovery may take several weeks, during which your doctor may recommend restricting activities.
