Thoracic Outlet Syndrome Surgery
Thoracic outlet syndrome surgery consists of one or two procedures to treat thoracic outlet syndrome (TOS). TOS happens when the blood vessels or nerves are squeezed (
compressed) in the area between the collarbone and lower neck. The goal of this procedure is to reduce the compression that causes TOS. During TOS surgery, you may have one or both of these procedures done, depending on what needs to be repaired:
Tell a health care provider about:
-
Any allergies you have.
-
All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
-
Any problems you or family members have had with anesthetic medicines.
-
Any blood disorders you have.
-
Any surgeries you have had.
-
Any medical conditions you have or have had.
-
Whether you are pregnant or may be pregnant.
-
Any recent symptoms of colds or infections.
