Stenting Brain Arteries: Opening Severely Narrowed Vessels to Prevent Stroke
Atherosclerosis—the accumulation of fatty plaque deposits along arterial walls—is well known for causing heart attacks and peripheral vascular disease. However, atherosclerosis can also develop within the major arteries inside the skull. Known as Intracranial Atherosclerotic Disease (ICAD), severe narrowing of major brain blood vessels (such as the middle cerebral artery, basilar artery, or intracranial internal carotid artery) restricts cerebral blood flow and stands as one of the leading causes of recurrent ischemic stroke.
When high-grade arterial narrowing (typically 70% to 99% stenosis) causes recurrent strokes or transient ischemic attacks (TIAs) despite aggressive blood-thinning and cholesterol medications, Intracranial Angioplasty and Stenting provides a targeted endovascular pathway to re-open the blocked vessel.
The Intracranial Stenting Procedure
Intracranial stenting is a specialized neuroendovascular procedure performed within a catheterization angiosuite:
-
Micro-Catheter Navigation: Under local anesthesia and light sedation, an interventional specialist inserts a thin catheter into an artery in the wrist or groin. Guided by real-time fluoroscopic imaging, the micro-catheter is navigated into the narrowed brain artery.
-
Angioplasty Dilative Expansion: A tiny micro-balloon is positioned across the plaque-filled segment of the vessel and gently inflated. This pushes the dense plaque outward against the arterial wall, expanding the inner channel.
-
Self-Expanding Stent Deployment: A flexible, mesh-like metallic tube (stent) engineered specifically for delicate intracranial vessels is deployed across the target site. The stent acts as a permanent internal scaffold, holding the artery open and stabilizing the underlying plaque to prevent micro-clots from breaking free.
Key Benefits in Stroke Prevention
Re-establishing normal arterial diameter delivers vital clinical benefits:
-
Restores Immediate Blood Perfusion: Increases oxygenated blood delivery to chronically starved brain regions.
-
Prevents Plaque Rupture: Covers raw atherosclerotic plaque, lowering the risk of sudden clot formation.
-
Dramatically Reduces Recurrent Stroke Risk: Provides structural stability for high-risk patients who have failed conservative medical management alone.
