Treatment of intracranial stenosis

An intracranial stenosis is a narrowing of the arteries supplying blood to the brain, which is generally caused by arteriosclerosis – a systemic disease leading to deposits of blood lipids, clots, connective tissue and lime.

If it is symptomatic and untreated, an intracranial stenosis presents a very high stroke risk and it should therefore be treated as a matter of urgency.

Alongside drug therapy, intracranial stenosis are treated in interventional neuroradiology by minimally invasive vessel expansion using a balloon catheter (percutaneous transluminal angioplasty – PTA). This treatment is supported if necessary by the implantation of a stent.

Acandis® offers the following products for the treatment of intracranial stenosis treatment:


Note: Magnetic Resonance Imaging (MRI) Information

Non-clinical tests have shown that the Acandis implant is suitable for MR-examination. After implantation, patients can be safely scanned with a static magnetic field of 3 Tesla.
The MR imaging quality may be affected if the implant is located in the area of interest. Optimisation of the imaging parameters is recommended.

For further information on MRI compatibility please consult the instructions for use of the respective product.
