General Information About the Test
Test Process and Preparation
It is generally performed under local anesthesia by inserting a thin, flexible catheter through an artery in the groin (femoral) or wrist (radial). The catheter is advanced to the cerebral vessels, a special contrast agent (dye) is administered, and serial X-ray images are taken.
Because local anesthesia is applied to the insertion site, pain is not felt. While the contrast agent is administered into the vessels, only a brief, temporary sensation of warmth may be experienced in the head and face area.
The procedure takes an average of 30-60 minutes. If performed through the groin, the patient rests flat in bed for a few hours afterward to prevent bleeding. If the intervention was performed through the wrist, the patient can stand up in a much shorter time.
