Sumario:BACKGROUND: Paravertebral catheters are generally inserted and removed without complications. However, catheter breakage occurs rarely. This is the first report describing breakage of a thoracic paravertebral catheter and retention of the catheter fragment within the patient. CASE PRESENTATION: A 65-year-old female patient complained of an unusual sensation in her back during postoperative chemotherapy for lung cancer. A catheter fragment was identified in the soft tissues of the back on computed tomography. The paravertebral catheter had been placed 2 years prior left lower lobectomy. The patient had neither neurological symptoms nor infection signs around the fragment. However, the potential side effects of chemotherapy, including coagulopathy and immunosuppression, increased the risk of late-onset hematoma and abscess formation around the fragment. Therefore, we surgically removed the catheter fragment. Analysis of the fragment revealed that the catheter had been severed by the cutting edge of the Tuohy needle or the suture needle. CONCLUSION: In this report, a paravertebral catheter fragment was retained in the posterior mediastinum for 2 years. The catheter was likely damaged during the insertion procedure. We suggest that catheters should not be withdrawn through the Tuohy needle, but be withdrawn together with the Tuohy needle. Although secure fixation of the catheter can be achieved with sutures, to reduce the risk of damage to the catheter, alternative methods, such as surgical tapes or skin glue should be considered. After removal of a catheter, its tip should be checked to ensure that the entire catheter has been completely removed. If a catheter fragment is retained within the patient, removal of the fragment should be considered according to the patient’s condition and risks.
