I had endovascular surgery to close a left-side dAVF with cortical venous reflux. The surgery was Aug 21, 2018 at UCSF in California, USA. Originally it was viewed as a low-risk procedure, and they would have used a transvenous approach. Ended up as a high risk surgery with arterial approach. Closed with 7 platinum coils and a bit of Onyx.
I’m now concerned about some after effects. Today, while cooking dinner, I moved quickly and got a bizarre unsteadiness, sort of a balance problem. I’ve had this happen 2x before, but this time it’s taking longer to resolve. No other significant symptoms. It is hard for me to walk heel to toe, but I compensate well. If I stand and close my eyes, I’m fine, no spinning. I just feel as if I’m listing to the left as I walk.
Location of dAVF is not completely clear. First indication from MRI suggested marginal sinus; now they think was also sigmoid sinus.
I’m curious if other folks have had similar balance problems that come on in a split second. No obvious cerebellar issues.
