Pagination or Media Count:
SVC syndrome results from increased hydrostatic pressure in the venous system distal to the SVC, through which blood flow has been diminished or obstructed. The source for obstruction may be an extrinsic process compressing the SVC or an intraluminal process, such as a venous thrombosis. The diagnosis is most often confirmed with computed tomography or venography. Diagnostic criteria include the demonstration of obstruction as well as the opacification of collateral venous systems. The following case demonstrates the most common radiographic findings of SVC syndrome as well as several therapeutic options available. Finally, important radiographic landmarks consistent with pathology are demonstrated throughout the case.
