Endovascular embolization is significantly less invasive than common surgical procedure. It might be done by itself however it's usually applied ahead of other surgical treatments to help make them safer. It does this by decreasing the dimensions on the brain AVM or maybe the chance of bleeding.

As a consequence of its spot, within the boundary involving artery and vein, these vessels show quite possibly the most turbulence. Surgical clamps often might be applied to be a circulation reduction technique.
For lesions that require distal limbs such as fingers and toes, tourniquets might be utilized to protect the idea from the digit if it is not affected and likewise the opposite nonaffected digits if in proximity.
