This morning, Ben drove me down to Boulder to undergo another test — a TCD, or transcranial doppler. I didn’t know what it would entail except that “it wouldn’t hurt”.
Which it didn’t — not really. They put a ring around my head, and then attached two ultrasound receivers to it. (No problems yet; that was painless, except that it was a little tight.) Then they gave me an IV. Boy, that part screws me EVERY TIME. Fortunately, Dr. Fanale found a vein after two tries; however, the tries *hurt*. He poked me, then swiveled the needle around; not as bad as the LAST time I had an IV (for my CAT scan), but painful nonetheless.
Once I was all hooked up, Dr. Fanale extracted a tiny amount of blood through the IV needle, mixed it with saline and water, and then re-injected it. The first time he did it, there was nothing. Then, he had me do a valsalva maneuver; that is, push like I’m having a baby or a really big poo. :) Oh boy — that changed everything. The machine went “BEEP!!!” and the monitor showed large spikes. “Is that a bubble?” I asked. “Oh yes — that’s a BIG bubble.” Apparantly, they normally grade your bubble response based on the graph shown on the computer. “What grade am I?” I asked. “You’re off the scale,” said Dr. Fanale. “We usually count the number of bubbles we see, but there are too many too do that on your scan.”
I was probably beaming at this point. Coolness! Way out there coolness! I wasn’t stressed out about not knowing what caused my strokes (or so I thought), but now … I feel SO much better. I read about a study conducted with cancer patients; they were more anxious waiting for a diagnosis than they were after receiving it, even if it was a terminal diagnosis. I think I understand that now.
A little explanation. Bubbles are significant (i.e. bad) because they mean that bubbles (or clots) in your blood can travel from one side of your heart (the venous side) to the other (the arterial side). Usually, the clots/bubbles get filtered out by your lungs, but a hole allows them to go straight through. The good news is that it’s fixable! Without surgery! Well, it’s minor surgery. They thread a patch up to your heart through your leg.
But, insurance probably won’t cover the procedure :( Apparantly, the FDA hasn’t approved it yet. I could get in on a clinical trial, but I WANT IT FIXED. I want it out of me. Without a PFO (patent forman ovale, the name of the “hole”), I don’t need to be on coumadin (yay!).
However, as Ben so kindly points out, this doesn’t exactly solve the “Why me? Why now?” question. 20% of people have a PFO, and only a lucky few of us get strokes. Why am I so prone to them? Probably because of my birth control pill, Dr. Fanale said, but he can’t be sure. I could get this thing fixed, go off the coumadin, and still have another one. We asked for statistics on this, and he said, “In our office, there are only 8 people like you who’ve had this done.” Apparantly, it’s fairly uncommon — except in young adults with cryptogenic strokes. “I can tell you, though, that I am sure that this is the cause of your strokes.”
He sent me home with the name and number of a cardiologist who specializes in TEE, and who can repair the PFO — and a good feeling that I haven’t had in a long time. I am so grateful for the folks who diagnosed this. Thank you. :)
