Nonmalignant superior vena cava syndrome : Pathophysiology and management

Superior vena cava (SVC) syndrome occurs following obstruction either from external compression or internal thrombosis or scarring. In the past, treatment was limited to medical therapy or surgical bypass but now percutaneous revascularization presents a viable therapeutic option. We present our experience in the percutaneous therapy of patients with nonmalignant SVC syndrome and review the condition with regard to its pathophysiology and management. © 2005 Wiley-Liss, Inc.
