The Pipeline Embolization Device, or PED, has revolutionized treatment for unruptured brain aneurysms. Tiny coils, glue, or mesh stents are used to promote clotting and close off the aneurysm. Monitoring devices (a blood pressure cuff on your arm, an oxygen monitor on your finger and EKG leads on your chest) will monitor your blood pressure, breathing and heart during the procedure.

The first-choice access route was the radial artery in 62 patients (87.3%) and the femoral artery in 9 (12.6%). Normally, on x-ray the blood vessels are relatively invisible. Coil embolization is a minimally invasive procedure to treat an aneurysm by filling it with material that closes off the sac and reduces the risk of bleeding.
