Recently did a Lt L4/L5 TFESI on a 50 y/o lady and felt the procedure went very well with good epidural flow, non-mylegraphic pattern, and negative DSA. Patient started reporting a postural headache the day after the procedure and has now lasted for almost a week. She went to the ER and work-up was negative. Naturally they think she has a PDPH and my PA prescribed her some Fioricet and went through the whole protocol of what to do. Planning on doing a blood patch tomorrow although I know it is rare to get a dural puncture with TFESI if done properly. My question is if I should tackle it from an interlaminar approach as I have read a few articles about a transforaminal approach. Any suggestions greatly appreciated.
