I believe there was a good vascular surgeon, Dr. Harold C. Urschel Jr. . DOnt know if he is still there

And though I do not know whether he is good or not, Dr Nath at the Texas Nerve and Paralysis Institute in Houston.

The Dellon INstitute (nerve surgeon) has a location in Dallas.

You might want to consider a trip to Denver though, the TOS mecca of docs.

Good luck
