SVC obstruction

Alternative names:

superior vena cava obstruction; superior vena cava syndrome

Treatment:

The goal of treatment is relief of the obstruction.

Diuretics may be used to relieve swelling.

The cause must be identified and treated. This may include radiation, chemotherapy, surgical removal of tumors, or other treatment. Surgery to bypass of the obstruction is rarely performed.

Expectations (prognosis):

The outcome varies depending of the cause and the extent of obstruction.

Complications:

• cerebral edema ("brain swelling"), possibly fatal
• throat swelling (laryngeal edema) with airway blockage

Calling your health care provider:

Call your health care provider if a lung tumor is present and symptoms indicate SVC obstruction may be present. Complications are serious and sometimes are fatal.
