Does anyone know where Dr. Richard Hsu is currently working. I am looking to find an expert in treatment of MALS and Dr. HSU name keeps appearing in my searches. I have called different numbers found in internet searches and most lead to a call center related to some organization called the vascular group. The numbers route to a call center and I can getting conflicting answers from them. Some operators tell me that Dr. HSU still works there and some tell me he has left the practice. If anyone knows of any Doctors that specialize in MALS in Minnesota, that would also be helpful. The results on my test have unfortunately been conflicting. CT with contrast said mild gastric artery stenosis with possibility of MALS. But ultra sound was negative. Was hoping for more testing to sort this out, but am running into nothing but roadblocks. My current doctors want to explore other things that don't really seem to fit the symptoms of stomach pain. Any advice is appreciated, thank you.
