Benign superior vena cava syndrome with uncontrolled pleural effusion by calcified mediastinal lymphadenopathy: Surgical management

Abstract

This report describes a rare case of benign superior vena cava syndrome (SVCS) accompanying recalcitrant pleural effusion developed secondary to extrinsic compression by anthracotic calcified mediastinal lymphadenopathy which was corrected by surgical bypass graft. An 81-year-old female presented with recalcitrant pleural effusion for several months despite of medical treatments. SVCS developed progressively without any other radiological evidence of malignancy or active infection on initial chest computed tomography (CT). A follow-up chest CT scan taken one month later revealed a poorly-defined mass-like lesion encasing the SVC. Near total collapse of the SVC due to circumferential compression by massive anthracotic calcified lymph nodes was noted in the surgical fields. A bypass graft was performed using an artificial vessel instead of endovascular treatment because of severe adhesion. The abrupt SVCS and uncontrolled pleural effusions completely disappeared after surgical correction. © Journal of Thoracic Disease.
