For patients with chronic pain or cancer-related pain, the most common indication for sympathetic block is to control visceral pain arising from malignancies or other alterations of the abdominal and pelvic viscera. When it is recalcitrant to conservative care, or if the patient is intolerant to pharmacotherapy, consideration of sympathetic blocks or neurolytic procedures is considered. Potential advantages of a neurolytic procedure, compared with spinal and epidural anesthetic infusions, include cost savings and avoidance of hardware. Interventional therapies that target afferent visceral innervation via the sympathetic ganglia offer effective and durable analgesia and improve multiple metrics of quality of life.
