A three-dimensional stereotactic technique is presented as an improvement in precision needle placement for percutaneous diagnostic and therapeutic procedures. methods. This method uses transaxial computed tomography (CT) imaging for the selection of the optimal target path, and it employs a three-dimensional stereotactic device designed to match precisely the CT parameters in a three-dimensional space. results. In selected cases, we reached targets as small as 1 to 2 cm while avoiding vital structures. conclusions. In our hands, in selected cases, this has been a simple, safe, and accurate technique for improvement of percutaneous diagnostic and therapeutic procedures under CT guidance.
Sixty-nine patients with documented and contained disc herniations underwent percutaneous discectomy. The procedure was carried out with a new stereotactic device mounted on the floor and positioned over the computed tomographic scanner. In each instance, this device provided accurate insertion of the needle and localization of the aspiration probe (Nucleotome) within the appropriate area of the disc. Aspiration of the herniated nucleus pulposus was accomplished in every patient, and no complications were encountered.
