Do blood vessels regrow or is the blood supply permanently diminished?

Thank you for sharing your excellent question.  The majority of the blood supply that remains comes from both named arteries as well as arborization of others to maintain the viability of the skin.  Over time there is some angiogenesis and new vessel creation between the muscle fascia and tummy tuck flap of skin but the vessels are not to the same size as the original ones.  Hope this helps.

Some studies have shown that blood vessels can regrow into the abdominal area after surgery. However, there are limited information as to how much they can regrow and how fast. Usually, blood supply into the abdomen after surgery does not cause complications and is of little concern post op depending on the skills and techniques used by your surgeon. Be sure to select a board certified plastic surgeon with ample experience in these kind of surgeries to make sure you are properly cared for.
