A new 'nanoparticle'-based imaging technique could improve the accuracy of brain tumour surgery, according to lab work by US scientists. The Stanford University scientists were able to precisely remove glioblastomas in mice by using the tiny particles to home in on and highlight the brain tumours. The imaging technique uses three types of brain scan before and during surgery.

Johns Hopkins neurologists report success with a new means of getting rid of potentially lethal blood clots in the brain safely without cutting through easily damaged brain tissue or removing large pieces of skull. The minimally invasive treatment, they report, increased the number of patients with intracerebral hemorrhage (ICH) who could function independently by 10 to 15 percent six months following the procedure.

The U.S. Food and Drug Administration approved a new device that provides neurointerventional surgeons with another tool to treat brain aneurysms without performing open surgery.
The Pipeline Embolization Device (PED) is a flexible mesh tube made of platinum and nickel-cobalt chromium alloy that can be used to block off large, giant, or wide-necked aneurysms in the internal carotid artery, a major blood vessel supplying blood to the front of the brain. The device can also reduce the likelihood that an aneurysm will rupture. To implant the device, the Pipeline is attached to the end of a catheter, which is inserted into an artery in the leg. The catheter is threaded into the carotid artery and into position at the aneurysm where the Pipeline is expanded against the walls of the artery and across the neck of the aneurysm, cutting off blood flow to the aneurysm. The blood remaining in the blocked-off aneurysm forms a clot which reduces the likelihood the aneurysm will grow bigger or rupture. Aneurysms successfully treated with the Pipeline will often shrink over time.
