I'd agree with Astern's comment descriptions of thoracic and vascular surgeons. My surgeon was a vascular surgeon. In my case, there was a surprise in surgery. Surgery ended up taking more than twice as long as expected due to a very large bone growth on the first rib. I've been told that this type of bone growth is very uncommon. A scalenectomy wouldn't have worked for me. This side is doing great.

I have a hypertrophic C7 transverse process on the other side. I've been told that it's not considered a cervical rib because it doesn't communicate (i.e. touch) the 1st rib but it does impinge on the brachial plexus. I will be having surgery this summer to have this side addressed.
