Blood Patch

With apologies to Neil Young, it's a case of out of the arm, and into the back. That's probably enough of the song lyric mash-ups too. The blood patch is a procedure where they draw some blood out of your arm, and inject it into the spot where they previously did the lumbar puncture (or epidural block, or whatever). The blood congeals, and closes up the hole in the dura and thus stops the CSF leak. That's what is supposed to happen, and the good news is that it worked! The headache subsided after a short time and have all but gone. I've been resting all weekend, and looking forward (not!) to another infusion on Monday.

I found the protocol differences between Australian hospitals and the Mayo clinic to be quite interesting. At the Mayo, lumbar punctures for the purpose of extracting some CSF are mostly done by a technician without the aid of imaging, and they only require you to rest for 30 minutes following the procedure. When I had mine done earlier this year, they did it under x-ray to make sure they found the right spot. It could be my neuro requested that because he knows how much I hate needles, and to make the experience less uncomfortable. The other thing they do here is make you lie flat for 2-4 hours afterwards, to ensure the hole closes, and minimize risk of a CSF leak.

This might just mean that my Mayo Clinic experience is finally over, some days after my return. Have been reflecting on the whole thing, and will post about that shortly.

The tap that keeps on tapping

With apologies to Cyndi Lauper, there's a hole in my back that comes all the way from Rochester. The headache that I've had since last Friday is most likely a result of a CSF leak. This is a side effect of the lumbar puncture I had at the Mayo Clinic, where they stuck a hole in my back to draw out cerebro-spinal fluid, and the hole has not properly closed.

So what's the solution? Poke my back again, and this time inject some of my own blood which will help close the hole. I'm booked into go to shortly to have this procedure done.

This is really getting to me. I agonized as to whether to just keep resting and hope that the hole closed on its own, or to have another uncomfortable procedure to close it, and decided this morning to take this route. It should give me a little more certaintly that the headache will stop once and for all.

Of course I also have to book in for more IVIg juice, and have decided with my neuro to just do one day (instead of the usual two), and do that on Monday after a weekend of rest.

and the results are ...

I really need to learn to adjust my expectations. The spinal tap was supposed to explain/reveal so much about specifically what condition I had, and the reason behind the side effects. Instead, the results are inconclusive, and I am left feeling flat, exhausted (is it the hot weather, the return to work, or a side effect?), and as uncertain as ever.

The protein levels were elevated, but not sufficiently to indicate CIDP over MMN. There was slight inflammation, but not sufficiently to confirm aseptic meningitis. Could be that the meningitis was more clearly indicated if we had done the spinal tap sooner after the initial IVIG treatment (it's been over six weeks), and now we are seeing only a residual inflammation. So, to summarize the test results in lay-speak: "it might be this, but on the other hand, it could be that, and the side effects might have been because of the other".

Bottom line: my neuro is putting me on a short (three week) course of Prednisone in the hope that it might reduce the inflammation, and therefore the headaches. They may also have an effect on the primary condition. And I am left still wondering, and have to pick up some more Panadol - the bulk size *sigh*.

more tests

Had a review with the Neurologist today, which confirmed that remains some increased strength in my hands after the initial IVIG treatment. It's not back to 100%, but it's better than it was a couple of months ago. Being just the first treatment, we must now sit back and see how long it lasts.


Some questions remain unanswered, like why I still have headaches, and he suspects that I may be suffering from an uncommon side effect of IVIG - aseptic meningitis (aseptic as in not the nasty form of meningitis that is really dangerous, but rather the benign one that gives headaches instead). There is also still some doubt as to whether what I have is MMN or actually CIDP. He expressed this possibility earlier, because of the way certain nerves were affected, and this doubt was also indicated by comments from another doctor who reviewed my case, and asked for further information.

So the obvious thing to do is to stick a needle in my back and extract some fluid - the magical cerebrospinal fluid which contains (we hope) the answers to the mysteries that lurk within my body. The lumbar puncture, or spinal tap, is something I've seen plenty of times on TV in medical dramas. I guess the only good thing about having one is that I won't see it - I'll be facing the other way trying to think of something distracting. Do you think they'll let me listen to my iPod during the test? My fear of needles keeps being tested by all these damn tests and treatments, and is something I will just have to get used to.
