Unruptured multiple ICA aneurysms

Posted by watermelonsugar25 @watermelonsugar25, Jun 26, 2025

Based on her family history with Moya Moya, aneurysms and epilepsy my sister did a cerebral angiogram a few weeks ago. She was diagnosed with multiple (3) ICA unruptured aneurysms. They are on the small side: on the right 1.5mm and 2.6mm and on the left, 1 mm. Doctor is suggesting two options either close monitoring or a stent. Because the aneurysms on the right are pretty close to each other, he is recommending a stent. Has anyone gone through this? Should we seek a second opinion?

Interested in more discussions like this? Go to the Stroke & Cerebrovascular Diseases Support Group.

@watermelonsugar25 I just had a flow diverter placed for my unruptured post communicating cerebral aneurysm which is 6 mm bilobed, with daughter sac.

I am so glad I did it now, because I witnessed my uncle go through a ruptured aneurysm and he barely survived.

I am a former professor and all the research I have done about my specific aneurysm lead me to choose intervention instead of monitoring.

The prospect of brain surgery is scary, but the angiogram stent placement is a quick surgery and has relatively quick recovery compared to clipping.
And it’s such a huge relief following surgery because I was more afraid of my unruptured aneurysm than I was of surgery.

I saw Dr. Lanzino at Mayo Rochester and he is amazing!

I had a 5 mm. brain aneurysm coiled 7 months ago. The neurosurgeon wants me to now have another cerebral angiogram to check the coils. Whereby the cerebral angiogram (with multiple x-rays and contrast dye) is necessary to diagnose precisely and plan for the coiling procedure, I have read that an MRA ( no x-rays) can be used afterward to monitor the coils. But my doctor is ignoring my messages on "My Chart" requesting the MRA scan instead of the cerebral angiogram. He did tell me when the coiling procedure was done 7 months ago that he would do another cerebral angiogram to check it and I can only assume he is holding firm to that recommendation. However, as I said, from what I've read the MRA scan has evolved to the point that it can be used to monitor the coiled aneurysm and avoid unnecessary x-rays. Just wondering if anyone else who checks this forum has had an aneurysm coiled and what was your follow up protocol.

@mkoch my husband’s ruptured. It was catastrophic but the quick actions by our neurosurgeon to coil it saved his life. He had his first angiogram post rupture this past Aug. It showed minor leakage which they will monitor auth a repeat angio in April. MRA would not have shown that. He had no issues and I had him home later the same day.

@watermelonsugar25 - have you gotten a second opinion for your sister? Did you decide to go forward with monitoring or a stent?

@lisalucier We went ahead with the stent for the two aneurysms on the right side, while the 1mm aneurysm on the left will just be monitored for now. She had the stent placed in August, and her body is still adjusting—she’s been experiencing some brain fog and occasional confusion. In six months, she’ll have another angiogram to check that everything looks good.

Since there had been several cases of ruptured aneurysms in my family and my brother had a ruptured brain aneurysm (they actually found he had three, one ruptured) I got checked and they found I also had a small aneurysm. Mine had vascular access so a repair would be simple (or relatively simple), two separate neurosurgeons recommended I had it repaired. They repaired it in 2017 with a stent, after that they monitored the evolution with angiograms and MRIs, in 2020 I had to get a second stent as the first one had proven not sufficient. Both surgeries were embolizations, similar to the angiograms, using catheter through the groin. Recovery is fast as it is minimally invasive. I still get checked every 2 years and it seems to have worked now.

@houston13 just curious as to how you realized that the first stent wasn’t working? My sister is having headaches, brain confusion and she had the stent installed in August for the two anneurisms on the right. We are still close monitoring the small aneurysm on the left. I am so glad you are doing well now!

If you don’t want to have a stroke have the stents put in. Usually >5 mm in size is when they get concerned but you’ve got many close together and if they rupture as a group it will be worse for the patient. If I was in your position I wouldn’t hesitate.

@jenatsky thank you. My sister got the stent on the aneurysms that were close together on the right but docs did not want to touch the one on the left as it is 1mm.

@watermelonsugar25 Hi, in my case it was proper monitoring, my surgeon followed up the first stent surgery with a combination of angiograms and MRI/As. I had no symptoms, without the follow up angiograms I wouldn't' have known. I believe he turns to MRAs only once angiograms show positive outcome. Right now I still have MRA/Is every 2 years, my last surgery was in 2020

Got it! My sister had her stent in August so technically she should have an angiogram again in Feb? Or did your doc recommend them earlier? I am concerned that she has a lot of brain fog, some headaches, confusion and also numbing on a specific side of her body. Did you experience that as well after stent was installed?

@watermelonsugar25 I’m not sure every surgeon follows the same schedule but I’m almost certain mine was done 6 months after the embolization and probably had another one 6 months after that one. I had so many angiograms with the two procedures, I lost track, I joked with the surgeon he should just instal a zipper in my groin.

Jokes aside, I had no symptoms whatsoever before or after the surgery, maybe slight headaches after but that’s it Your sister should consult with the surgeon, everyone is different and aneurysms are in different locations, have different shapes and sizes and we all react differently to procedures. The good news is that she is being taken care of, a lot of people find out the have it when it becomes an emergency, and that the aneurysm could be treated with embolization. She should be seen as often as it is necessary and if she feels any symptoms like she is right now.

Hope she feels better soon!!
