Various minimally invasive treatments can be used for patients with a brain aneurysm, a weak spot in the blood vessel wall. They involve “endovascular” techniques accomplished by navigating a thin catheter (hollow tube) through the blood vessels to the location of the blockage.
The endovascular approach may offer shorter treatment time, less pain and faster recovery than traditional open surgical procedures.
Coil embolization, or “coiling,” is the most common endovascular treatment. Physicians use a catheter to place tightly packed platinum coils within the aneurysm to encourage clot formation, close the aneurysm, and prevent bleeding into the brain.
Another technique uses “flow diversion devices” to route blood flow away from the aneurysm and down the normal course of the blood vessel.
