I am wondering how to go about having Mayo Clinic can give me a second opinion on my possibly having May Thurner Syndrome. Based on my history of blood clots in my left leg, beginning with my first pregnancy at 23, he suggested we should check. The MRI I had did not rule out May Thurner. He explained that next they'll insert a probe up my left leg to do an ultrasound and an xray to see if my right iliac artery is pressing on my left iliac vein. If so, he said the treatment is to have a stent put in the vein. BUT he said they may not have the correct size of stent, and that I may have to come back after the diagnosis to have the stent put in. That makes me think of a mechanic working with an incomplete set of tools, and I don't know what to do next, but I don't want that! Is there an online review? Or do I need to get an appointment?
