Thank you Jan,
I'll leave a quick run down of my experience for those who follow on -
I went to Wessex Neuro Southampton last Wednesday for pre-assessment during which I had many tests including an ECG and bloods. I met one of the two Doctors who would be involved who explained fully the procedure, including the possibility of needing a stent and why. I left with a handful of blood thinning pills to take that evening and the next morning. I was back there at 07:30 on Thursday morning and down in the angio suite by 9am. A nice little syringe full of pre-med sent me off and the next I knew it was after 2pm and all over bar the shouting. The procedure had been completely successful with one small issue. For the op they had gone in both sides of the groin and the left side incision was still weeping a little so I had to spend an extra couple of hours down there with pressure on to stop it leaking. In the end it did.
Back up to the ward where I met up with one of the nurses I remembered from my previous stay. I had a bed right by the window so I could get lots of fresh air which I love. Standard obs at regular intervals, blood pressure, temperature, grasp the hands, pull toward, push away, etc etc. The only bad part of this period was throwing up while snoozing, side effect of the anaesthetic I guess. Most unpleasant. Only the once though thankfully!
The following day, Friday, had several drips removed, arterial and otherwise and the catheter (nasty things). One of the Doctors came down to see me and confirmed all was OK, the anny was filled and a stent wasn't required, and my next visit would be in six months for an MRA scan instead of an angio. I had to drink lots then once my bladder started working normally following the removal of the catheter I was free to go and left for home mid afternoon. I was able to walk out of the hospital and to the car park. Total time in hospital just shy of 32 hours.
Since I got home I've been taking it easy, catching up on my reading. I have been getting a recurrence of some of the tiredness and a fair old headache for the first few days but this has now eased and it's been a day or two since it was bad enough to go for the pills.
In conclusion, all my fears were unfounded. The staff at Wessex Neuro carried out the procedure flawlessly and looked after me as well as anyone could hope for, and I am a lot happier to know that I no longer have an at-risk anuerysm at large in my head. It was definitely worth electing to carry on with the extra coils.
All the best
