Flow diverters, tubular implants that divert blood flow away from the aneurysm, are a newer treatment option. This stops blood from moving inside the aneurysm, which then encourages the body to heal the problem. The body can then reconstruct the artery with the aneurysm. A doctor may recommend using flow diverters if their patient has a large aneurysm that can't be treated using other procedures. Typically, the surgery recommendation will be made by a neurosurgeon as they work in conjunction with neurologists. The most common aneurysms flow diverters are used for are unruptured saccular aneurysms with wide necks. 

These are hard to coil since the coils can fill the artery, and they're difficult to clip because of the wider opening. Circumferential and fusiform shape aneurysms can also be treated with flow diverters. Before flow diverters were invented, there wasn't any treatment option available for many types of intracranial aneurysms. Researchers use a flow diverter grading system to determine how effective the treatment is. After patients receive a flow diverter, the degree of their aneurysm is subsequently measured on a five-point scale. The highest grade is four, which indicates the aneurysm has been completely obliterated.
