Summary
Subcutaneous peripheral field stimulation offers a safe and effective solution for chronic thoracic post herpetic neuropathic pain. This treatment provided significant, lasting pain relief for all patients in the study.
Area of Science:
- Neurology
- Pain Management
- Neurosurgery
Background:
- Post herpetic neuralgia is a persistent, debilitating pain condition.
- Management options for this neuropathic pain are limited and often ineffective.
Purpose of the Study:
- To evaluate the efficacy and safety of subcutaneous peripheral field stimulation for thoracic post herpetic neuropathic pain.
Main Methods:
- Four patients with intractable pain underwent subcutaneous peripheral field stimulation.
- A 7-day trial with percutaneous electrodes was followed by permanent implantation if successful.
- Pain scores (VAS) were monitored preoperatively, postoperatively, and at follow-up (average 28.2 months).
Main Results:
- All patients experienced persistent pain reduction exceeding 75% on the VAS.
- No treatment failures or complications requiring re-operation were reported.
Conclusions:
- Subcutaneous peripheral field stimulation is a safe and effective treatment for refractory post herpetic neuropathic pain.
- Careful patient selection and precise lead placement are crucial for successful outcomes.

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
