I have surgeons I can call on yes.
A dural tear that has rootlet herniation would be a distaster but extremely unlikely in a transforaminal approach. I'd say that your risk is similar to an epidural hematoma from a LESI. Smaller tears you can usually leave alone and you can endoscopically repair a medium sized tear. Again a dural tear is pretty rare transforaminally. If you pull on a nerve root well - don't do that know your anatomy.
@lobelsteve if you had to self manage every complication that could occur with your procedures you would be essentially doing nothing - why dont you just leave everything to the spine surgeon since if they get a complication they can manage it especially if your putting needles and neurostim leads in the spine or injecting cement into a vertebral body - the same can be said for the spine surgeon that speers the kidney in the retroperitoneum going too far lateral on a transforaminal approach at L2/3 or L3/4 or causes a bowel or vascular injury during an ALIF. The fact there is a fellowship for this where the PD is a pain physician brings a lot of credibility to this procedure and its efficacy in our hands.
