We got home from the doppler test on my left and right carotid arteries. The unofficial good news is that the blockages haven't gotten any worse. Of course, my left carotid is completely blocked and that won't change and the right is still letting blood flow through. Tomorrow, we will find out what percentage of the artery is blocked. It had been 20 percent.
The other good news is that humans are created with a redundant set of arteries in the neck if one gets blocked. That's what happened on my left side. Arteries grew to replace my blocked one and its supplying blood to my face and my eyes. And then there's the Circle of Willis which takes over when needed.
I don't pretend to understand this all, but I'm impressed with the way God created humans. There's backup circulation at least for the carotids. I'm anxious to learn more.
Tomorrow, I have an appointment with the vascular surgeon to make all this official.
