@bs9652 - @Sammi is another member who had surgery w/ Dr. Cognetti. I can’t remember if she had IJV decompression, but I think she didn’t. Here are links to some of her discussions:
If you need an overnight stay in the hospital, even just for peace of mind, after your surgery w/ Dr. Cognetti, let him know that. I expect he will be able to arrange for you to be admitted to stay overnight after surgery.
