A/VTOS surgeries typically have a better success rate than those with Neurological involvement. I am fortunate (if you can even say that) that I mainly had/have vascular issues requiring the surgery. I did not have cervical ribs, however. My surgeon is Dr Michael Lavor- http://saguarosurgical.com/
He is EXCELLENT. He spent a great deal of time with me, went over all of my previous testing/results, and ordered a new viewing ultrasound of my vascular anatomy to confirm the diagnosis and also to be sure that there is was not a differential diagnosis also causing the same symptoms. The ultrasound was lengthy and thorough, completed in house for immediate results. I saw Dr Lavor right afterwards, discussed the results and created the surgery and recovery protocol. I have been a military spouse for quite some time, and he happens to be Navy reserve, so I can appreciate his background and approach all the more! He and his team are fantastic. Do a search for my posts, I go into detail about my symptoms, testing, surgery and post op experience. My left arm, is a new arm. I kid you not.
If there's anything else I can help with, please let me know!!
