Celiac plexus block effectively manages pain associated with hepatic arterial embolization (HAE). This procedure significantly reduces the need for analgesics, offering a safer alternative for patients undergoing HAE for liver cancer.

Area of Science:

  • Interventional Radiology
  • Pain Management
  • Oncology

Background:

  • Hepatic arterial embolization (HAE) is a palliative treatment for unresectable liver malignancies.
  • Significant post-procedure pain is a major limitation of HAE, often requiring high doses of narcotics.

Purpose of the Study:

  • To evaluate the efficacy of celiac plexus block (CPB) in managing pain following HAE.
  • To compare analgesic requirements in patients who received CPB versus those who did not.

Main Methods:

  • A retrospective comparison of 18 patients undergoing HAE with immediate CPB versus 19 control patients undergoing HAE without CPB.
  • Pain assessment and analgesic consumption were recorded for all patients.

Main Results:

  • All patients receiving CPB experienced pain relief without requiring intravenous analgesics during and for 8 hours post-HAE.
  • CPB patients required substantially lower overall analgesic dosages compared to controls.
  • Two patients experienced transient hypotension; no other complications were reported.

Conclusions:

  • Celiac plexus block is a safe and effective method for controlling pain after hepatic arterial embolization.
  • CPB should be recommended for patients undergoing HAE to improve pain management and reduce opioid use.
