Lumbar Sympathetic Block / Neurolysis


The lumbar sympathetic block is an injection consisting of a local anesthetic that is used to relieve chronic leg and foot pain. The pain is usually caused by conditions such as complex regional pain syndrome, reflex sympathetic dystrophy, vascular insufficiency, and shingles. Medications are delivered to the sympathetic nerves along the front side of the spine. The goal of the procedure is to reduce pain so that you can resume normal activities and physical therapy. Lumbar sympathetic neurolysis is reserved for patients suffering from ischemic rest pain in the setting of non-reconstructable arterial occlusive disease. Although, patients with complex regional pain syndrome, peripheral neuralgia, vasospastic disorders, and various other disease states such as plantar hyperhidrosis may also benefit. Lumbar sympathetic neurolysis is usually performed by using absolute alcohol, but other chemicals such as phenol, or other techniques such as radiofrequency or laser ablation are also considered.
