Summary
Accidental dural puncture during epidural catheter placement for stomach cancer surgery led to contrast medium leakage into the subarachnoid space. Management focused on preventing total spinal anesthesia and altering the pain management strategy.
Area of Science:
- Anesthesiology
- Neurosurgery
- Oncology
Background:
- Epidural analgesia is commonly used for postoperative pain management after major abdominal surgeries like gastrectomy.
- Accidental dural puncture during epidural catheter insertion can lead to complications such as post-dural puncture headache and, rarely, total spinal anesthesia.
Observation:
- A 63-year-old man undergoing gastrectomy for stomach carcinoma experienced an accidental dural puncture during initial epidural catheter placement at the T10-11 level.
- Subsequent epidurography revealed contrast medium passage from the epidural space into the subarachnoid space, with opacification of the caudal cul-de-sac, persisting for at least 24 hours.
Findings:
- The initial epidural attempt resulted in cerebrospinal fluid (CSF) return, indicating dural puncture.
- Epidurography confirmed a persistent epidural-to-subarachnoid space communication, posing a risk for unintended high spinal blockade.
Implications:
- This case highlights the importance of careful technique and vigilance during epidural catheter placement, especially in patients undergoing major surgery.
- Prompt recognition and appropriate management, including altering the analgesic technique, are crucial to prevent serious complications like total spinal anesthesia.
- The findings underscore the need for advanced imaging and careful monitoring in cases of suspected epidural-subarachnoid communication.
