I’m hoping mentn34 will see this thread and come back to post since he has direct experience. I can offer some ideas but while I have about 70% occlusion, and it is causing some lightheadedness, I’ve had no treatments other than routine monitoring of it by ultrasound.

Your situation is different if they are sure this is a clot issue. Thickening and radiation damage to the carotid arteries is pretty common as a long-term complication from radiation treatment. Stenting has been routinely done, and I talked to a couple patients that have had vascular autogenous grafts of blood vessels from elsewhere being moved there successfully. But the idea of living with a clot seems counterintuitive, especially given your history, and I think it would be worth getting a second opinion from another vascular surgeon with experience in radiated patients soon. There are some quality people in the Boston area and I think it would be worth the trip once you identify the right person. If we don’t get a poster with more experience in the next couple days answering you, I will reach out to one in our science board for his ideas and report back. B
