I am not a doctor. Nor do I play one on my blog.
I am not a teacher. But I sometimes play one in my life.
So...that being said. Take the circulatory explanation for what it is. Simplistic. Rudimentary. And potentially riddled with errors.
Arteries carry blood away from your heart. Arteries have to be very strong so that they can withstand the pressure of the blood as it is carried through the body.
Veins carry de-oxygenated blood back to the heart. The walls of a vein are tissue paper thin. And they can be because they don't deal with the constant pressure.
The two are connected by capillaries. Capillaries connect the arteries to your muscles and organs. And then another set of capillaries join up with the veins. And it all starts over again.
Or at least that is the way it is supposed to work.
Today Michael had a follow-up angiogram. And we found out that Michael did not have an aneurysm after all. What he has is an arteriovenous fistula. Which basically means that in his brain, he has an artery that directly connects to a vein. And well. That vein had just had enough pressure. It bled. A lot. And all that bleeding mimiced an aneurysm. And all that blood. Well, it shielded the fistula.
Now that we have an actual diagnosis. We fix it. And by we. I mean the neurosurgeon. And what we are going to do is a little brain surgery. Next week. Because there is a 20% chance that it will bleed again. This year. But. As far as brain surgery goes, it's not supposed to be a big deal. And when it's fixed. It's fixed. But guess what? It's "elective" brain surgery. Maybe Michael will ask if they can do a little eyebrow lift while they are there.
So...what about you? What kind of elective surgery would you want? Did you ever want to be a doctor? Oh...and I sorta forgot about my own contest. Click here to see the winner of the "Bride and Prejudice" movie.
