Overview
If left untreated, patients with superior vena cava syndrome may progress to develop a complete obstruction and a decreased cardiac output with hypotension, leading to heart failure and death. Common complications of superior vena cava syndrome include airway obstruction, increased ICP, laryngeal edema and cerebral edema. The prognosis will vary depending on the cause of the syndrome, and the amount of blockage that has already occurred. Prognosis is generally poor, and the survival rate of patients with SVCS is approximately 10-20% at 6 months.
Complications
Complications that can develop as a result of superior vena cava syndrome are, the following:
- Airway obstruction
- Laryngeal edema
- Cerebral edema
- Decreased cardiac output with hypotension
- Pulmonary embolism
Prognosis
The prognosis of superior vena cava syndrome is good with treatment. Without treatment, superior vena cava syndrome will result in torpid clinical evolution associated with a 10- 20% mortality within 6 months. The presence of thoracic malignancies is associated with a particularly poor prognosis among patients with superior vena cava syndrome.
Prognosis is also associated with the acute or long onset of the disease. Acute onset, is relate with more severe symptoms because of absent collateral vein. Therefore there is no distention to accommodate an increased blood flow. However, chronic onset is related with less severe symptoms because there is a presence of collateral veins that compensate increased flow.
