Prehospital Care
Prehospital caregivers are aware of the superior vena cava syndrome (SVCS) diagnosis only on occasion.
The usual attention to airway, breathing, and circulation (ABCs) is required.
Superior vena cava syndrome only rarely manifests as a life-threatening entity; therefore, other causes for the symptomatology must be sought.
Emergency Department Care
Superior vena cava syndrome only rarely manifests as an acute emergency.
Attention to the ABCs is essential.
If patients are allowed to sit upright, they may experience some relief of the usual dyspnea.
Stabilize the airway, as needed, and consider steroids.
If cerebral/airway edema is present, consider diuretics; however, diuretics have not shown consistent benefit in the emergency department (ED).
Endovascular shunts are increasingly used, as are thrombolytics if a thrombotic cause is present.
After a tissue diagnosis, radiation and chemotherapy may be initiated.
Consultations
Over the last 10 years, considerable experience with endovascular stenting of superior vena cava syndrome has been achieved.[2] At many centers, endoprostheses have become the initial choice for palliative treatment of superior vena cava syndrome.
Emergent consultation with radiation therapy may be necessary, depending upon the acuteness of the presentation.
Because most causes of superior vena cava syndrome are related to lung cancer, a pulmonary or oncology consultation may be obtained.
Generally, considering the diagnosis in the ED is important. If the diagnosis is made de novo in the ED, only rarely is emergent consultation necessary. Exceptions include sudden airway compromise or acute superior vena cava thrombosis, which may occur from an indwelling catheter.
