Treatment Option for Refractory Postherpetic Neuralgia – Transversus Abdominis Plane (TAP) Block: Two Case Reports

Abstract

Postherpetic neuralgia (PHN) is a severe neuropathic pain syndrome. The treatment of PHN is complex and refractory in some patients. We present two cases with refractory anterior abdominal wall pain due to PHN that were successfully treated with transversus abdominis plane (TAP) block. The TAP block seems to be an alternative for patients with PHN who suffer from anterior abdominal wall pain accompanied by allodynia and hyperalgesia and do not respond to the existing conservative treatments.
