If you do not see yourself doing anything, but procedures go to a surgical subspecialty. IR is not a good choice. It can be very beautiful, but you may need to do a lot of DR besides.
Most IR jobs are a combination of IR and DR with DR almost 50% of what you do. The same is going for cardiology. They do almost 60% general cardiology. It is the environment in the pp, forget about your university.
And there is always turf issues. Be prepared to go back to DR. You may lose your turf to vascular surgeons. What happens if the oncology clinic starts sending the chemo-embos to vasc surgeons? I know, many IR people may start to argue. Even if it does not happen in a large scale, it may happen in your area. Nothing is in the realm of IR that can not be done by a surgeon. Don't forget that 15 years ago people where laughing at vascular surgeons and cardiologists for putting the catheter in IVC instead of Aorta. And now, IR fellows are begging for PVD cases.
Unfortunately many medical students choose IR as a short track to surgery. To many it is a way to escape the hardship of 5 years of surgery residency.
Don't take me wrong. IR is one of the greatest fields in medicine. It will likely thrive and expand. But always be prepared to switch back to DR and if you hate it, do not do IR. You have to do at least 50% DR in most places, job market may not be as good in the future, you may lose the turf at least locally and many other factors.Surgical sub-specialty is on the safer side.
Just know what you are doing to your life.
