Man Chris, there lots of different kinds of things a cardiovascualar surgeon like Dr Dake can do for a cardiac artery issue or a vein issue and they pick the one that works with the kind of problem the person has.
Obviously Jeff needs a stent; his vein squishes shut so it needs something to keep it open. You might need something else maybe angioplasty would be best in your case they have to see to know. That is what the venograms or MRV are all about: they actually look at the problem and see what it is FOR YOU. Its going to be different for all of us.
Like one person might have a valve that is all goofed up, maybe they put a stent there to keep it open, or maybe in a different situation it would be repaired, depends on the need for preventing backflow at that location.
Or maybe a person has a big fat old plaque sitting right next to the juntion between two veins, perhaps there they can do the balloon angioplasty....or maybe they remove it instead depending on the situation
All these dicisions are made my thevascular surgeon, that's why they go to school for so very long after medical school is done. These guys go to school for like 15 YEARS . 10 years of all the med school stuff then 5 more of vascular surgery.
They have lots of tools in their tool box....
btw I am not a doctor just a nurse so I just made up situations based on my limited knowledge. I didn't go to school for 15 years but I'm glad someone did!
