Flow diverter/stent 5 years after coiling. Please share your experiences

Dear @Rizwan6532 @oct20 @Moltroub and all,
First of all, thank you so much for sharing your experience. My neck was only 1 mm (“was” at my last check Oct 2021) but the aneurysm is slowly growing (still, a small one, 4-5 mm). My Neurosurgeon said also that we could wait and see but that placing a flow diverter would finally close the aneurysm and avoid a second rupture and having to make a second operation in an acute situation again.
It took me 4 months to decide and I finally signed up for the operation. The waiting time here (Austria) is pretty long due to lack of personnel and as I am not an urgent case I will probably do the operation sometime next year. I have concerns about it but the idea of having to face again a rupture in some years time when I will be more “aged” is not reassuring, therefore I have decided to go for it. My situation is similar to yours @oct20 and yes, it seems like a standard procedure for what we all have. Something that until 10 years ago they were not doing but now it’s the perfect solution for unclosed annies.
I’ll also have to be on dual platelet for 6 months and then Aspirin for… ? no idea - maybe the rest of my life, hoping that all will go well!
Thank you all for reassuring me and let’s hope for the best! Good luck to us all :slight_smile:

Good for you Iris! To take control of what we can is a huge step for ourselves and you made a giant leap IMHO! Unfortunately a shortage of medical personnel is worldwide I assume. My last procedure was also considered elective so on hold I went and then the follow up angiogram I didn’t know anyone on her team. For me that was unsettling as many had been there through all my angiograms and knew which music I liked and joked around with me. If I may ask, does your doctor plan on doing another imaging in six months or so, just to see how your aneurysm is doing?


@Moltroub Thanks! I guess I’ll have to do another imaging before the operation, I should do one anyway in October for my annual check - no idea if the standard check after operation is also every 6-12 months, but I’ll keep you posted. And yes, Covid had a huge negative impact on medical personnel everywhere in the world.

Now that I took the decision and signed up for the operation, I am feeling better, relieved. What scares me (but I try not to think about it) is the 5% possibility of something going wrong in the operation (these are the statistics) and that there is no way to know it in advance… but I think with all what we already went through, this is normal. :slight_smile:
By the way: Very happy to read about your improvements after operation! Thanks for sharing :slight_smile: :slight_smile: :slight_smile:

Thanks so much Iris! I’m uncertain to the risks statistics you’re referring to, cna you share the study, please ma’am? I just read an article on nih that was quite interesting, though didn’t have the risks stats. The authors were quoting some very old statistics though all the way back to 1961! Surely there’s more recent numbers with the improved technology is what I thought. I don’t discount the risks of everything from anesthesia on, it’s why I have a litany the morning of a procedure with my Neurosurgeon…did you sleep well last night, did you eat breakfast, did you go potty, how’s your allergies doing? One of her new team members years ago became quite miffed with me and said she’s a neurosurgeon. I said in my stutter, she’s human first and I certainly don’t want her sneezing, doing the potty dance, not fully awake or her brain wanting to know why she didn’t eat whilst guiding a catheter up my body in a main artery. A couple more angiograms later and he let me know he fed her as I had to wait until late afternoon for mine. She had some emergencies to deal with and they all know I don’t mind waiting. I’ve always imagined someone was pushed out of their slot so she could save my life!

Iris I am sorry to hear that this course of treatment is so different to that which I experienced and which I hear about more commonly in US. My Aneurysm
was in a precarious location and it was determined that the only viable solution was a flow diverter. I was on a blood thinner for several months, then graduated to a full strength aspirin and now take a baby strength aspirin for the rest of my life. A small price to pay for the result. I am told that the Aneurysm has stopped growing, so the flow diverter is doing its job.

It is surprising to me that your procedure is considered elective considering the amount that your Aneurysm has grown since your clipping. I wish you the best.

Dear @BrianS @Moltroub and all,
Thanks for sharing! And here are some more info to recap the situation: in Oct. 2017 I had an aneurysm rupture that was immediately coiled. My recovery was pretty fast I would say (when it happened, my left eye was paralysed and closes. It stayed so for two months, then started slowly to open up but still with double vision and then slowly it started to move normally and my vision was normal again).

From that moment on, I had to do 6 months checks, then once a year checks and now I have been offered the flow diverter operation - elective because the neck is open only for one millimetre and I’ve been told it is not so risky.

To all who are on medications after the flow-diverter operation: do you find that your life has changed for the better and what are the limitations you have?

@Moltroub the statistics I was referring to are quoted from the talk with my neurosurgeon, who said that 95% of the cases goes well and 5% have complications. In the “everything goes well” scenario flow diverter is described as the perfect solution because once done there are nothing to worry about for 20-30 years. So, until I’m 73-83 I should live worry-free :wink:

I’ve done my homework and found some videos online, in case someone is interested:

I’ve been told that until 10 years ago there was no other way than “wait and see” after a coiling) and that once the flow diverter is in place, the aneurysm will naturally shrink and close.

The 5% risk is the “usual risk” of an operation with full anaesthetics, plus what can go wrong in this kind of cases… that is still not 100% clear. He mentioned that some people don’t react well to the medication pre and post operation and then I read the full list of risks (you know, that list that they give you to sign for the authorisation…) and well, not a funny reading at all…

My main concern is very human and I can sum it up to: “I was already so lucky to survive to an aneurysm rupture and now, after 5 years, I am healthy: why should I go through another operation? Do I really risk to have another rupture?” But then I thought that hopefully all goes well and that it is always better to have a planned operation instead of waiting for something serious to happen and then having to react in an acute situation.

Here in Vienna the hospital is among the best in Europe for neurosurgery and I fully trust my neurosurgeon and his stuff, but I’m sure they would do different choices if they had more personnel. Let’s see…

All the best to you all and keep on smiling :slight_smile:
Thank you for your support!!!

@trust_level_0 Oh my gosh Iris! Thank you so much for, well everything! Thank you especially for clarifying the 5%! It helped me to understand.

And yes ma’am, the long list of things that can go awry is mind boggling, not on my fun list either. If I recall correctly, the majority is with anesthesia. When I had my stent put in I had a wonderful RNA that promised he would do his best to put and keep me in my happy place😂. He did and when I woke up, I woke up rather quickly and was doing really well. It was the first procedure that didn’t set me back for months.

I know we have a lot of members who have had a flow diversion stent put in, I’m hoping they’ll come and tell their experience. I’ve done a broadcast (hopefully) to all our members. I don’t often do it so I may have gotten it wrong.

To install my stent, I was on generic Plavix prior to my procedure and then 325 mg aspirin afterwards and quickly put on just 81mg aspirin which I will take the rest of my life apparently. The aspirin is enteric coated aspirin which helps coat the stomach, etc from any potential damage as I understand it.

Hi y’all - I’m not sure I can help but I will share my experience. When I had my subarachnoid hemorrhage in January, 2018, I also had an unruptured one on the other side (posterior communicating artery). They coiled both. However, the medication they sent me home with to prevent vasospasms literally made me sick as a dog.
They ended up stenting one side in April, 2018 as angiogram showed problems. Angiogram in August of 2018 was okay. Plavix then 325mg then 81 mg aspirin
They switched to MRAs I guess in 2019 or so. MRA in 2021 was abnormal and they stented the other side (through the wrist this time) was placed on Brillinta in conjunction with 81 mg aspirin. Followup MRA in August of 2021 showed tiny residual of most recent stent. Neurosurgeon hoped that when I was off the blood thinner it would close off the rest of the way. Brillinta stopped in October of last year.

I guess I find out later this month whether he was right about it sealing off but he told me last October that I “have an awful lot of hardware” in my head. My first thought was well no chit, you put it there but I didn’t say it.

The surgical nurse did tell me when I went back for my second angiogram and I told her about my stabbing head pains that most people that had the stents suffered from those. Something my doc never told me because he pronounced me fixed. lol
I’m still taking 81 mg aspirin.
And I’m very sorry, I forgot my manners, I wish you luck with your procedure!!!


I can add my experience here. I got coiled 20 years ago after an accident. From that i was suffering frequent headaches and ocular migraines that got worse over the years. 3 years ago there was found another aneurysm in that area, 7mm wide necked probably because of a weakened vessel due to the accident decades ago. The doctors said flow diverter would be the best choice. So i had it done and had a quick recovery without major issues since 2019. Sometimes headaches, but far and in-between and not too bad. Migraines are gone too. I take plavix 75mm daily with no issues because i can’t stomach the aspirin. Last mra from spring shows everything is still fine. So i am glad I had that done. The benefits outweigh the risks IMO. Chances are everything will be ok. All the best to you all! If you have any questions feel free to text me.



I there! I was diagnosed with a giant aneurysm of 35mm in October 2018 (unruptured), got clipped and a flow diverter two weeks later. I took clopidogrel for 6 month in combination with aspirin, now only 100mg aspirin per day for the rest of my life. I´m fine so far, but the annie is still there and there is still a little blood flowing through it (maybe because it was so big). I noticed the annie because of double vision, still experience a blurred vision from time to time, but not so often. Headaches occur, mostly in the evenings, but they are acceptable.
All in all the procedure was ok, and the recovery too. At the moment I have some strange neurological issues with tingling legs and arms, but doctors aren´t sure if that has to do with the annie.
I wish you luck - everything will go well!

Hi Iris-Can I ask what your surgeon meant by ‘there is nothing to worry about for 20-30 years’? I had my flow diverter placed 10 years ago at the age of 34 and that’s a bit worrisome! Thank you!


Hi Restolz! Sorry - I did not mean to scary you… I’m not sure if he meant (since I’m 53) that I would be ok until the end of my days or, literally, 20-30 years. I will ask him next time I see him (which could be in several months) and will get back to you. But if your neurosurgeon did not say anything like this, then don’t worry at all. :slight_smile: …I know, it’s not easy… :slight_smile:
All my best to you and all and thank you again everybody for sharing your own experience! Very useful!
Ciao :-* Iris

Thank you for the quick response! Please do let me know if you find out anything else. Hope you’re doing well :slight_smile:

If you Trust your neurosurgeon then do exactly as he suggests. I am on a 325 aspirin for the rest of my life and people I am around understand the consequences of my bumps and how I bruise easily.
As for your concerns and another operation, your surgeon has your best interest at heart (and his reputation).
Forget About the What Ifs and Focus on the Positives!! (My Mantra)



I’m not sure if what I can add will be sufficient, since I am so new to all this, but I have to go back and have an angiogram in 6 months (8 months after my coiling and stent).

See what an angiogram will say, then listen to your dr. they really know best. I know it’s scary, but they are the experts. If you have a good relationship, and they have a good reputation, then you have to trust them.

My .02 cents.

Best of luck to you… xo


Dear @Longbeard: I love your mantra and I’ll make it mine too :slight_smile:

And dear @Julie2022 thank you so much for your answer: I do think the same, I trust my doc and his team and since they already saved my life once, well… I can only think positive!

Fingers crossed and all the best to all of you! Good luck to us!



Hi there! I am about 7 weeks out from having a PED(Pipeline Embolism Device) placed. I was dx on May 3rd with an unruptured fusiform PCA 7mm aneurysm. I am VERY lucky and blessed this was found prior to rupture. This was a rare and hard to treat aneurysm. There also was a little bulging sac off the vessel. I had an angiogram and balloon occlusion test at the end of May to see if they could sacrifice the parent vessel, but they couldn’t due to loss of vision and loss of motor movement during the balloon test. Mid June I had a flow diverter pipeline stent put in. I had to take baby aspirin and plavix for 2 weeks prior to the surgery and am still on both. Not sure how long I will be on the plavix but the baby aspirin for life. As far as we can tell the surgery went pretty well, will know more in December when I have an angiogram. I am having fatigue, headaches and vestibular issues but for the most part doing pretty good, considering. I only spent one night in the ICU. No big scars or major deficits. I hope this helps and good luck.


Thank you so much and sorry to reply only now …in December! How are you?
All my best wishes :green_heart:
Iris :sun_with_face:

Dear @restolz, I finally talked to my neurosurgeon again and as promised I asked the question if the diverter has to be replaced after 20-30 years and the answer is… NO :relaxed::relaxed::relaxed::relaxed::relaxed::relaxed::relaxed::relaxed: So no worries at all. He said after 6 months from the implant of the diverter there’s going to be a check and then an angiogram that should define if the aneurysm finally is completely cured/closed/not dangerous any more and then, if so, that’s it and I can go on with my life and not worry about it anymore. We’ll check of course which medicines I’ll have to take and for how long and basta/finito/no worries and big smiles!
I hope this helps and sorry to have made you worry for nothing!
With all my best wishes :green_heart:
