Neuroplasty using Racz catheter with O-arm fluoroscopy: case reports

Abstract

C-arm fluoroscopy is a standard apparatus for neuroplasty using Racz catheter. We reported two cases of performing that treatment with O-arm fluoroscopy. Case 1: A 75-year-old man with C8 root area pain. Although he had previously undergone conventional therapies, his pain has remained for 5 years. We applied neuroplasty using Racz catheter with O-arm fluoroscopy. It was difficult to detect where the catheter was through lateral imaging because of overlapping humeral and shoulder bones. But CT imaging by O-arm fluoroscopy could show location of the catheter easily. Case 2: A 60-year-old woman with L5 root area pain. The pain was due to pelvic fractures by traffic accident and it remained for 2 years. We applied neuroplasty using Racz catheter with O-arm fluoroscopy. CT imaging by O-arm fluoroscopy showed the catheter was located in intervertebra foramen. O-arm can be a useful fluoroscopy when performing neuroplasty using Racz catheter.
