Endovascular coiling is a procedure used to treat brain aneurysms by inserting coils into the aneurysm via a catheter inserted into an artery. The coils fill the aneurysm, causing it to clot and preventing blood from flowing into the weakened area, thus reducing the risk of rupture. This minimally invasive technique is less risky than traditional surgery and has a shorter recovery time.

Endovascular coiling is highly effective in treating certain types of brain aneurysms, preserving brain function, and preventing life-threatening complications like hemorrhagic stroke.
