Intracranial Stenosis
Cerebral Stenosis or Intracranial Atherosclerotic Disease (ICAD)
Call for an AppointmentDuke's experts identify and treat intracranial stenosis, which occurs when blood flow to the brain is restricted by narrowed arteries or plaque buildup (atherosclerosis) in the small twisting vessels deep within the brain. These blockages can greatly increase your risk of stroke. Neurologists and radiologists use sophisticated imaging to diagnose the severity of your condition and aggressively treat stenosis to reduce your risk of stroke or brain damage. If surgery is recommended, our highly skilled neurosurgeons perform minimally invasive or traditional surgery to open blockages and restore blood flow.

Tests
Transcranial Doppler Ultrasound
A specialized ultrasound that uses sound waves to examine blood flow within your brain. This noninvasive, painless test takes about 30 minutes.
MRI or CT Scans
High-resolution images of brain vessels indicate where the brain's blood supply may be restricted by a narrowed or blocked artery. These can be performed with or without contrast dye. These tests take about 30-60 minutes and are virtually painless. When MRI or CT scans are used to examine blood vessels (angiograms), they are called MRAs and CTAs.
Cerebral Angiography
Through a small incision, a catheter is inserted into a large artery and threaded through the circulatory system. A contrast dye is injected, which shows neuroradiologists -- specialists in the nerves found in the brain and spine -- areas of concern. Overall, this test takes about an hour and requires you to lie flat afterward for two to four hours.
