Continuous cervical paravertebral block (CCPVB) can lead to epidural spread, a complication causing upper-extremity weakness. Careful needle placement and prompt recognition are crucial for managing this risk during CCPVB procedures.

Area of Science:

  • Anesthesiology
  • Pain Management
  • Regional Anesthesia

Background:

  • Continuous cervical paravertebral block (CCPVB) is increasingly used for upper limb surgery pain control.
  • Epidural spread is a known complication of paravertebral blocks.
  • Understanding the mechanism of CCPVB complications is essential for patient safety.

Observation:

  • A case of bilateral upper-extremity motor weakness occurred post-CCPVB in a young male patient.
  • Fluoroscopy revealed the catheter tip within the C7 neuroforamen.
  • Contrast injection confirmed unintended epidural spread.

Findings:

  • The patient's symptoms resolved within 4 hours without lasting sequelae.
  • Medial catheter placement, potentially due to needle bevel direction, is hypothesized as the cause.

  • This case highlights the importance of precise needle manipulation during CCPVB.

    • Implications:

    • Meticulous attention to needle bevel orientation is mandatory to prevent epidural spread during CCPVB.
    • Early recognition and management of adverse events are critical for patient outcomes.
    • These principles are applicable to other continuous paravertebral blocks (thoracic, lumbar, sacral).
