A Case of Thoracic Disc Herniation Effectively Treated with Interventional Radiology Computed Tomography-Guided Percutaneous Endoscopic Radiofrequency Annuloplasty Using a Disc-Fx (original) (raw)
Thoracic disc herniation is rare compared with cervical/lumbar disc herniation, accounting for only 0.25% to 1.00% of all patients with disc herniation. A patient consulted another hospital with lightning pain in the right flank, and a few days later was referred to our department. On physical examination, pressure pain was the most marked at the Th9 to 12 areas. Magnetic resonance imaging of the lumbar vertebrae led to a diagnosis of multiple disc herniation involving the Th9/10 to L4/5 areas. To treat the Th12/L1 herniated discs, intercostal nerve/epidural blocking was performed, but was ineffective. Therefore, blocking of the right Th12 nerve root was conducted under fluoroscopy. The symptoms slightly subsided. Subsequently, Computed Tomography - Discography was performed, leading to a definitive diagnosis of right lateral herniation at the Th12/L1 level. Percutaneous discectomy of the thoracic vertebrae may cause complications, such as pneumothorax and intervertebral arthrosis; therefore, operations must be carefully conducted.
