Neurologic complications occurred in 522 examinations (2.63%), and 27 of these (0.14%) were strokes with permanent disability. The catheter used to deliver the contrast dye can puncture an artery, causing bleeding into the surrounding brain tissues. Blood clots can also form on the catheter and block arterial blood flow. Cerebral angiography provides high-resolution, three-dimensional, pathoanatomical data about the cerebral vasculature and also allows real-time analysis of blood flow. They include: stroke (if the catheter loosens plaque inside a blood vessel) Results from an angiogram are more accurate than other forms of imaging including CT, MRI or US in making vascular diagnoses.
