Residual necks

This is my first time posting here. I just found this site! I had a brain aneurysm rupture just over three years ago, it was coiled. I am just wondering if anyone else has had one that was coiled and hasn’t fully occluded. Mine the dome is fully occluded but it still has a residual neck that hasn’t closed up. I am due to go again in November for a MRA and follow up visit with NS. I start getting nervous when these MRAs get close. Wondering if anyone else has this problem. Thanks.
