Where to do a CT guided pudendal nerve block?
CT-guided pudendal nerve block The CT-guided pudendal nerve block should be made at the site of potential compression. The patient is placed in the prone position. Five- millimeter collimation CT images are obtained from the head of femur to the ischium. The ischial spine, sacrospi- Fig. 6. A Pudendal nerve block at the ischial spine.
Why does a CT-guided nerve block injection take place?
The corticosteroid reduces inflammation at the site, and therefore reduces pain and other symptoms caused by the inflammation. The procedure takes place in the CT suite because a CT scan is used to guide a radiologist precisely to the area that needs to be treated. What are the benefits of having a CT-guided nerve block injection?
Can a truncal block be used for pudendal neuralgia?
This type of neuralgia may be relieved by a truncal anesthetic block (anesthetics and corticoids) used in treating other entrapment syndromes. The aim of the present report is to demonstrate the computed tomographic (CT) anatomy of the course of the pudendal nerve and the method of CT-guided truncal block.
What is the anatomy of the pudendal nerve?
Anatomy of the pudendal nerve The pudendal nerve is a mixed nerve (sensory and motor) derived from the somatic component of sacral roots S2– S4. It supplies the anal and urethral sphincters, the pelvic floor muscles, and anal, perineal, and genital sensitivity.

How are guided injections used for pelvic pain?
Many different guided injections can be performed for pelvic pain 1. The aim of a pudendal nerve block is to cannulate the pudendal canal and give injectate, often steroid containing, so achieving a perineural injection.
