Good luck pursuing this Dej! I hope you get some benefit.
I'm not sure about it either anymore. Short story: saw Dr. Dake at Stanford for assessment and the MRV showed 90% blockage. Came home and found an interventional radiologist who was excited to do it because he was friends with Dake. Got on the table, was pumped with drugs, and they filtered the catheter up. Turns out when they got in they couldn't find the blockages anymore. The IR was puzzled and had no answer. I've been doing pretty well so never followed up on it. But it will be interesting to see what pans out over time.
