Superior Vena Cava Syndrome
The Superior Vena Cava (SVC) is the main blood vessel that transports de-oxygenated blood from the upper body to the heart.
The SVC is a short vein located in the anterior right Superior Mediastinum, which is the area found in the mid-line of the Thorax (Drake et al. 2010). The vein is surrounded by many structures involved in the respiratory and circulatory system including the right Bronchus and the Mediastinal lymph nodes (Martini & Ivonne 2004). Figure 1 is a coronal CT image of a human chest, highlighting the heart and the location of the SVC. Superior Vena Cava Syndrome (SVCS) is characterised by the obstruction of blood flow through the SVC (Cohen et al. 2008). As the vein is relatively thin walled, obstruction of the vessel is often caused by external compression from pathological

This can be determined through the use of various scans (Imm n.d.).
Both Small Cell Lung Cancer and Lymphoma are often treated using chemotherapy as this is the most common treatment for sensitive tumours.
If it is caused by tumours that are not sensitive to chemotherapy, then a form of radiation therapy can be used (Cohen et al. 2008).
The treatment of the cancer causing compression on the SVC will treat the superior vena cava syndrome.

If the obstruction of the vein is linked to a blood clot, then appropriate treatments to remove/dissolve the blood clot would be necessary.
Common thrombolytic drugs include Streptokinase, tissue plasminogen activator and recombinant or genetically engineered tissue plasminogen activator (Cohen et al. 2008). Most thrombolytic treatments work by activating an enzyme called Plasminogen, which works to get rid of the fibrin mesh that traps the platelets. The blood clot then becomes soluble.
Most cases of SVCS are not life threatening, once the cause of the obstruction has been
