Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Superior vena cava syndrome (SVCS) develops from obstruction of venous drainage from the upper body, resulting in increased venous pressure, which leads to dilation of the collateral circulation. SVCS is most commonly caused by vascular compression from malignant mediastinal tumors. Dyspnea; swelling of the face, upper extremities, and trunk; chest pain; cough; or headache may be present. Physical findings include dilation of collateral veins of the trunk and upper extremities, facial edema and erythema (plethora), cyanosis, and tachypnea.
