What Is a Lumbar Sympathectomy?

The purpose of sympathetic ganglion resection is to remove the sympathetic innervation of the diseased segment arteries, relax vascular smooth muscle, dilate blood vessels, and improve blood flow. The sympathetic ganglion fibers that dominate the lower limb vascular movement mainly originate from the lateral horn cells of the chest 10 to the waist 2 and 3. The postganglionic fibers are branched into the lumbar plexus and sacral plexus via gray communication, and are distributed through the femoral, obturator and sciatic nerve To the branches of the lower limb femoral artery. However, this improvement is quite limited, the effect is difficult to last, and the effect is worse for cases where the main problem is mechanical obstruction rather than vasospasm. This type of surgery is currently rarely used.
