The short version
This study tests whether blocking the blood vessels that feed a brain tumor before surgery makes the surgery safer.
Who this trial is for. This study is for people with brain tumors that have a very rich blood supply. Examples are some meningiomas, hemangioblastomas, and some tumors that spread to the brain. Doctors use a thin tube in a blood vessel to block the tumor's blood supply. Then they remove the tumor with surgery 24 to 72 hours later.
Where it stands. The study will look at how well the blood supply gets blocked. It will also look at blood loss, blood transfusions, how long surgery takes, and how much tumor is removed. It will track any problems caused by the procedure. The study has not reported any results yet.
What this means, and what it doesn't
What it could mean: Some brain tumors bleed a lot during surgery, which can make them hard to remove. This study may help show whether blocking the blood supply first is safe and helpful. If you have this kind of tumor, you could ask your care team about it. Only the study team can decide who can join.
What it doesn't mean: A study is a test, not a proven treatment. Taking part does not mean you will be helped. The procedure has its own risks, and the study is checking for them. This is not a cure for a brain tumor.
