Cerebral angiogram or angioanaylsis is the test of choice when there is suspected intracranial bleeding in an acute setting. The purpose of this test is to determine if there is an underlying cause of the bleeding or any other blood-related pathology. It is also used for follow-up after intervention in patients who underwent endovascular treatment of a brain aneurysm. Cerebral Angiogram is commonly done to identify the underlying causes of stroke in young patients.
Preparation for Cerebral Angiogram
The patient should be examined thoroughly to rule out any other conditions which may be causing the bleeding. If there is any history of recent trauma or surgery, it should be enquired about. There should be no history of recent or past consumption of any drugs which may cause vasoconstriction or vasospasm. Any history of chronic hypertension should be enquired about.
The patient should be advised to take nothing by mouth before the procedure. There should be no food or drink in the stomach for at least six hours before the procedure. If there is any history of recent intake of any medications, they should be withheld for at least 12 hours before the procedure.
The patient should be brought to the radiology department on the day of the procedure. The procedure should be done after a full night’s sleep. The patient should be positioned on the examination table with his head resting on a headrest.
