Incidental unintentional breakage of epidural catheter in supralaminar area: A case report.

Abstract

Background: Among some of the known complications, breakage of epidural catheter, though is extremely rare, is a well-established entity. Visualization of retained catheter is difficult even with current radiological imaging techniques, and active surgical intervention might be necessary for removal of catheter fragment. We report such a case of breakage of an epidural catheter during its insertion which led to surgical intervention.Case Description: A 52-year-old, an 18G radiopaque epidural catheter was inserted through an 18G Tuohy needle into the epidural space at T8-T9 interspace in left lateral position. Resistance was encountered. While the catheter was being removed with gentle traction along with Tuohy needle, it sheared off at 12 cm mark. After informing the operating surgeon and the patient, immediately an magnetic resonance imaging and computed tomography (CT) scan were done. CT scan with sagittal and coronal reconstruction was done. Epidural catheter was visualized at D9 lamina-spinous process junction who was removed by surgical intervention.Conclusion: Leaving of epidural catheter puts the anesthetist in a dilemma. To evade such an event, it is important to stick to the traditional guiding principle for epidural insertion and removal. In spite of safety measures, if event occurs, the patient should be informed about it. Surgery is reserved for symptomatic patients or asymptomatic patients to avoid future complications.
