This is an excellent question. Believe it or not, you theoretically •could• do that pathway. We just reviewed a CV of a guy from a program in who did that exact pathway (IM->neurocritical care->neurointervention). As far as I could tell, he was practicing neurointervention. There are 2 major roadblocks - 1)You will have a near impossible time getting someone to train you in neurointervention after you finish the NCC fellowship. It's hard enough for a neurologist (there are plenty of places that only train radiology and/or neurosurgery). And 2) Once you train , it will be near impossible to find a job. The value of a neurointerventionalist who is neurology trained is that he/she can take stroke call. The value of a neurointerventionalist who is neurosurgery trained is that he/she can interpret imaging and do other body IR procedures. neurointerventionalist who is neurosueg trained is that he/she can operate. It is an extremely slim market for someone who is boarded in internal medicine but wants to run a neurointervention program.
