Role of mediastinoscopy in superior vena cava obstruction

Cervical mediastinoscopy and anterior mediastinotomy in superior vena cava obstruction.

STUDY OBJECTIVES There is general agreement regarding the diagnostic efficacy of cervical mediastinoscopy (CMDS) and anterior mediastinotomy (AMDT) on patients with superior vena cava obstruction (SVCO), but controversy exists concerning the safety of these two diagnostic methods on that particular subset of patients. The purpose of the present study is to evaluate the safety and diagnostic eff...

CT findings in superior vena cava obstruction.

T HE CLINICAL manifestations of SVCS were first described by Hunter in 1757, secondary to a syphilitic aneurysm of the ascending aorta.’ SVCS usually has an insidious presentation and eventually leads to a collection of signs and symptoms that together are diagnostic of the disorder. Obstruction of the SVC may result from external compression or intrinsic thrombotic disorders, and leads to prox...

Superior vena cava obstruction in cystic fibrosis.

Benign obstruction of the superior vena cava.

Hunter' was the first to report a case of superior vena cava obstruction. Ehlrich2 et al. and McIntire and Sykes3 have extensively reviewed the world literature. Obstruction of the superior vena cava due to primary endothoracic malignant tumours or aneurysm is not uncommon, accounting for 94 per cent. of our cases, but benign lesions causing obstruction of this vessel are rare Oschner and Dixon...

Systemic-to-pulmonary venous shunt in superior vena cava obstruction.

Superior vena cava obstruction is associated with multiple venous collaterals. There is an unusual pathway involving pulmonary venous collaterals in which systemic veins drain directly into the left heart, resulting in a right-to-left shunt. We report here a rare case of systemic to pulmonary venous shunt on both hemithoraces in superior vena cava obstruction associated with Budd-Chiari syndrom...
