First question: are you entertaining any other specialties? If you are at all uncertain, then explore other options. If not, and you are neurosurg all the way, then I would recommend neuroIR and neurorads. I also did sub-Is in vascular surg and ENT. I thought both of those were useful, not only for the skills overlap, but because you’ll interface with them in nsurg either in competition for CEAs or in collaboration for skull base and the like.
