Hello googs,
Vascular TOS surgeries usually have better results that nerve related.
Recovery might take longer than what the dr suggested, so keep that in mind , maybe it will and maybe it won't.
Plan for longer just in case, and don't be upset if it does take longer.
A good solid recovery is what it important.

I'm hoping you have an experienced surgeon, that has done quite a few of these, always best to keep the odds in your favor.
