A refined percutaneous rhizotomy with DSA-guided ethanol for the second-line treatment of trigeminal neuralgia.

Background: Percutaneous rhizotomy is a group of techniques used to treat trigeminal neuralgia. Radiofrequency thermocoagulation (RF) and Chemical Rhizotomy (CR) using glycerol are among the most frequently used methods. We have recently refined Ethanol Rhizotomy (ER) under Digital Subtraction Angiography (DSA) guidance.
