The accuracy of the lesioning plays a crucial role in the results of Dorsal Root Entry Zone (DREZ) surgery. The DREZ lesioning utilizes different techniques: radiofrequency, laser, ultrasound, electrocoagulation, with the size and the shape of the lesions determined by the technical parameters of the respective technique. The aim of this study is to assess the effectiveness of the dorsal horn suctioning as a DREZ lesioning technique applied for the treatment of neuropathic pain of spinal cord and/or cauda equina injury origin. The geometry of the lesion was determined by the natural properties of the cord tissue itself.
