If you want to do only stroke, a good number of IRs in the community are doing stroke thrombectomy. You can learn the skill. However, you will probably face some challenges for credentialing in the future or if you want to work in a big center. But at the level of community hospital you are good to go for the foreseeable future.
If you want to do high end NeuroIR, you have probably wasted a few years which is fine in the grand scheme of things. The standard path is Neuro and then NeuroIR.
You have to choose to do either high end NeuroIR (stroke is an exception here) or body IR. It is hard or impossible to find a job to do both.
