Although many conditions that affect the brain’s blood vessels can be diagnosed using MRI or CAT scans, a cerebral angiogram can help provide a definitive diagnosis, aid in planning treatment or provide detailed images of brain arteries that are too small to even be visible with other kinds of imaging. The neurological complications were transient (TIA 1, generalised seizure 1) in two patients (0.5%), reversible (stroke) in three (0.8%) and permanent (stroke) in five patients (1.3%). Usually, cerebral angiography is used after another test has already found an abnormality.Angiography is used to help detect and diagnose acute stroke.

The most concerning risk, though very small, is a possibility of a stroke – damage of arteries supplying the brain during the procedure, or formation of thrombi (clots) around or within the catheter can cause a stroke. COVID-19 is an emerging, rapidly evolving situation. This factsheet explains what the procedure involves and how to prepare. Multivariable analysis was employed to identify patient and procedural factors significantly associated with neurologic complications. There can be rare instances of allergic reaction to the dye being administered. Bleeding and swelling (hematoma) can occur at the incision site in the groin. Radiographs are taken as the dye works its way through the cerebral circulation. The contrast dye used to make blood vessels visible can trigger a variety of allergic reactions in some people. This site needs JavaScript to work properly. Br J Surg 1988; 75:428-430.

Reactions range from mild skin irritation, itching, a drop in blood pressure, difficulty breathing, and loss of consciousness or death. During the procedure, an incision is made in a large artery, usually in the groin, and a catheter is introduced through the incision and guided through the artery to the area of the brain to be examined. Radiology. A brain angiogram (cerebral angiogram) is a test (also called a procedure) that looks for problems with blood vessels and blood flow in the brain.You may have a bruise where the catheter was inserted, and you may feel sore for a day or two after a brain angiogram.You can do light activities around the house.

With the precise and detailed imaging made possible by contrast dyes, a cerebral angiogram procedure can also help with planning cerebral treatments for conditions affecting blood vessels, such as balloon angioplasty or the placement of stents. Brain angiogram risks also include the fact that the catheter may cause damage to a blood vessel. Factors independently associated with an increased risk of neurologic complication included the indication of atherosclerotic cerebrovascular disease (odds ratio [OR], 2.494), the indication of subarachnoid hemorrhage (OR, 2.523), and the comorbidity of frequent transient ischemic attack (OR, 1.674).
