Do I need a vascular delay to save belly button? 5'6" 175lbs

You did not post photos, so I cannot be specific. However, if the incision was not made around the belly button, just dividing the stalk should not cause loss. Please avoid any form of tobacco.

You may a have a perfect Tummy Tuck and remove the old scar of your original belly button.
There are multiple options and techniques to create a new belly button. It is totally unnecessary to try to save your original bb.
Be encouraged!!! Your full Tummy tuck will be a total success this time.

Hi Fantastic415791,
Your belly button is a scar, at the site where your umbilical cord used to go through the abdominal wall to your liver. When you were born, the umbilical cord falls off, and the wound heals as a dent...otherwise known as a belly button.
Thus, the belly button's primary blood supply comes from its attachment to the abdominal wall. When the belly button is "floated" in a mini tummy tuck, its connection to the abdominal wall is divided, and the blood supply is divided too.
A "delay" procedure can improve the blood supply but even after a delay, it's likely that the belly button wouldn't survive in this situation. . I would suggest talking with your plastic surgeon about the possibility of removing your belly button if it looks questionable during the tummy tuck, and having a neo-umbilicus created at that time.
Hope this helps.
