How is inferior vena cava syndrome treated?

The treatment of vena cava compression syndromes commonly involves stenting or radiation. Expandable metallic stents have been used to treat IVC compression caused by hepatic tumors [11]. Tumors that compress the SVC, such as lung cancer, are generally radiosensitive [12].

How can you tell the difference between SVC and IVC obstruction?
