Researchers monitor brain aneurysms without X-rays

It is claimed the method is potentially less invasive and more accurate than current methods, and is simple enough for patients to use at home for frequent monitoring.

According to UBC, brain aneurysms occur when the weak wall of an artery carrying blood to the brain begins to bulge and balloon out. If the artery ruptures the haemorrhage can lead to stroke, brain damage or death. To create a plug that will prevent blood flow to the weak area of the artery, surgeons typically insert an embolisation implant made of microscopic coils of platinum.

UBC researchers have now devised a monitoring technique that is said to be compatible with existing coil-implantation tools and procedures. In the study, the team proved that it is possible to use the platinum implant as an antenna to wirelessly detect blood levels and indicate implant failure. Their results will appear in a forthcoming issue of the journal Biosensors and Bioelectronics.
