This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient, not a study of a new treatment.
The short version
One man lost the skin on the back of his head after doctors blocked scalp blood vessels ahead of tumor surgery, and surgeons were able to repair it.
What was studied. This is a report on a single patient. A 63-year-old man had a procedure called embolization before surgery for a meningioma on the surface of his brain. Doctors used a glue-like material called Onyx to block arteries at the back of his head on both sides, plus the arteries that feed the covering of the brain.
What they found. The skin at the back of his head lost its blood supply and the tissue died. The bone underneath then got infected. He needed several operations to clean out the dead and infected tissue. Surgeons covered the area with tissue moved from his thigh and hooked it up to blood vessels near his temple that had been left untouched. At 5 months, the area had healed and stayed healed.
What this means, and what it doesn't
What it could mean: Blocking a lot of scalp arteries before meningioma surgery can sometimes leave the scalp without enough blood flow. If that happens, surgeons can often fix it with tissue taken from another part of the body. The authors say teams should think about this risk ahead of time and leave some blood vessels intact in case a repair is needed later.
What it doesn't mean: This does not mean embolization is unsafe or should be skipped. It is one person's story, not a study that compares treatments or tracks a group of patients. A single report cannot tell you how often this happens, or who it might happen to. Nothing here is a new treatment, and it is not a cure for anything. If you are facing this kind of surgery, ask your own care team what their plan is.
