It can be used to control an aneurysm, excessive bleeding, or to cut off the blood supply to a tumor. The WEB Aneurysm Embolization System is indicated for use in the following arteries located in the brain (middle cerebral artery (MCA) bifurcation, … Coil embolization is an alternative to surgery. A SEPS was placed at the time of the angiogram to further reduce the size of the subdural hematoma. Radiologists trained in brain and nervous system imaging (neuroradiologists) usually conduct imaging tests.Tests used to diagnose brain AVMs include: 1. A catheter is then placed through the sheath and advanced into the neck vessels. All Rights Reserved. A cerebral tumor embolization is a procedure in which a catheter is placed into the patient's groin and carefully navigated into the blood vessels supplying the tumor under X-ray guidance. For the blood vessels to be visualized, they need to be filled with contrast material (x-ray dye). This is a way of blocking off part of a blood vessel that is causing problems.
