ABSTRACT

Placement of an epidural blood patch is the gold standard treatment for a postdural puncture headache when conservative measures have failed. If unsuccessful in relieving the symptoms, a second epidural blood patch may be warranted. However, when the accepted gold standard treatment has failed, alternative therapies may be pursued. A pterygopalatine ganglion block has been shown to be effective as an alternative to epidural blood patch placement. This case demonstrates the use of a suprazygomatic pterygopalatine ganglion block as a rescue technique for failed repeated epidural blood patch, with complete and permanent resolution of the headache.
