Palliative nonvascular interventions

Interventional radiologists are often called on to help with quality of life issues in end-stage cancer patients. Many times, the discomfort can be directly associated to the tumor mass itself, but in other instances, tumors can cause secondary obstruction of normal structures that can lead to patient distress. As with most palliative care patients, their medical conditions are not conducive to major surgery; therefore minimally invasive techniques are ideal for the treatment of these conditions. The following discussion addresses the various nonvascular interventions available to these patients, including the indications and limitations of these procedures.
