All done. I can't honestly say that a 3+ hour operation during which one is completely conscious has a great deal to recommend it, but there was relatively little discomfort, and the surgeon was very happy with the outcome. I've had lots and lots of long strands of platinum inserted in the aneurysm, and when he'd finished it looked in the X-Ray image just like a ball of wool, with all the strands tangled up and intertwined. The blood will clot around this structure and should completely seal off the aneurysm. From now on, though, I'll probably be setting off airport metal detectors!
I'm now back on the ward having my vital signs measured every 30 minutes, but so far, so good. If all continues OK I should be back home tomorrow.
