Summary

A novel C-arm-guided approach for pudendal nerve block (PNB) in the prone position offers an effective alternative for perineal pain management. This technique successfully blocked the pudendal nerve in all patients without complications, overcoming limitations of other methods.

Area of Science:

  • Pain Management
  • Interventional Radiology
  • Anesthesiology

Background:

  • Pudendal nerve block (PNB) is a key intervention for perineal pain.
  • Existing PNB techniques (transperineal, transvaginal, CT/sono-guided) have limitations including cost, complexity, and accuracy issues.

Purpose of the Study:

  • To evaluate the efficacy and safety of a C-arm-guided approach for pudendal nerve block (PNB) in the prone position.
  • To establish a simpler and more reliable method for performing PNB.

Main Methods:

  • A C-arm-guided approach was developed for PNB in the prone position.
  • Needle placement was guided by fluoroscopy to the ischial spine tip.
  • A mixed anesthetic solution was administered for the block.

Main Results:

  • The C-arm-guided PNB technique was successfully performed in all 25 enrolled patients.
  • No adverse effects or complications were reported in relation to the procedure.
  • The method proved effective in achieving the pudendal nerve block.

Conclusions:

  • C-arm-guided PNB in the prone position is an effective and safe alternative to current techniques.
  • This approach overcomes the limitations associated with existing PNB methods.
  • It offers a practical solution for diagnosing and treating perineal pain.
