- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a report on 4 people, not a trial that tested it against other options.
The short version
Four men had deep brain surgery through a small tube made from a heart stent.
What was studied. This is a report on 4 men, ages 49 to 77. Their surgeons did not have a store-bought port for deep brain surgery. So they used a balloon-expandable covered vascular stent instead, as a temporary tube to reach the deep spot.
What they found. Three of the men had brain tumors. The surgeons removed all of the tumor in all three cases. Scans after surgery confirmed this. The fourth man had bleeding deep in the brain. The surgeons removed 30 cc of that blood clot, which was the amount they planned to take out.
What this means, and what it doesn't
What it could mean: Deep brain masses are hard to reach without moving healthy brain tissue. A tube like this lets the surgeon work through a narrow path. This report suggests a stent could stand in when the usual port is not available or costs too much. That could matter most in hospitals with tight budgets.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a report on 4 people only. There was no comparison group, so we cannot say this works better or worse than other ways of reaching deep brain masses. The authors say it may be a workable option in select cases, not that it should be standard. Your own surgery team decides what tools fit your case.
