Conclusion: Depending on individual circumstances including age, overall health and the condition in question, a cerebral angiogram can be the most effective tool for diagnosing and treating many conditions affecting the brain’s vascular system, particularly those that might be missed using noninvasive scanning procedures. The dye allows doctors to observe blood flow in “real time” and identify areas where that flow is blocked or slowed. Bleeding and swelling (hematoma) can occur at the incision site in the groin.

There is a small risk that blood will form a clot around the tip of the catheter, blocking the artery and making it necessary to operate to reopen the vessel. Neurologic complications of cerebral angiography: prospective analysis of 2,899 procedures and review of the literature. Although a cerebral angiogram is an important tool for making precise diagnoses of many cerebral conditions that affect the brain’s vascular system, this procedure does have risks, some of which may be serious.
