INTERVENTIONAL RADIOLOGY SERVICES
Stroke Interventions
Stroke interventions include image-guided procedures used in the evaluation and management of acute and selected recurrent cerebrovascular events. These interventions are performed based on clinical presentation, imaging findings, and multidisciplinary decision-making.
Overview
Stroke interventions focus on restoring or improving blood flow to the brain in patients with ischemic cerebrovascular disease. Timely imaging assessment and precise image-guided techniques play a critical role in identifying suitable candidates for intervention.
Interventional radiology contributes to both emergency stroke care and planned management of cerebrovascular disease using minimally invasive approaches.
Clinical Indications
Stroke interventions may be considered in patients with:
- Acute ischemic stroke
- Recurrent or progressive cerebrovascular symptoms
- Large vessel occlusion
- Transient ischemic attacks (TIA) requiring evaluation
- Suspected cerebrovascular narrowing or blockage
- Stroke risk related to carotid or intracranial disease
Procedures Performed
- MRI and CT interpretation for stroke evaluation
- Cerebral digital subtraction angiography (DSA)
- Mechanical thrombectomy for acute ischemic stroke
- Intracranial and extracranial angioplasty
- Stenting for selected cerebrovascular lesions
- Image-guided evaluation of cerebral circulation
Role of Interventional Radiology
Interventional radiology enables detailed evaluation of cerebral blood vessels and targeted treatment using image guidance. Procedures are performed through small vascular access points, allowing precise navigation within cerebral arteries.
In appropriately selected patients, interventional techniques may reduce tissue damage and improve outcomes compared to delayed or non-targeted approaches.
Approach and Patient Care
Stroke interventions require rapid assessment, accurate imaging interpretation, and coordination with neurology and critical care teams. Each case is evaluated individually to determine procedural suitability and timing.
Post-procedure care focuses on neurological monitoring, complication prevention, and coordinated follow-up as part of comprehensive stroke management

Frequently Asked Questions
When are stroke interventions required?
These interventions are considered when imaging and clinical findings indicate reduced or blocked blood flow to the brain that may benefit from targeted treatment.
Are stroke interventions emergency procedures?
Some stroke interventions are performed on an emergency basis, while others are planned after detailed evaluation, depending on the condition.
Do all stroke patients require interventional procedures?
No. Treatment decisions depend on stroke type, severity, imaging findings, and overall patient condition.
Is imaging necessary before stroke intervention?
Yes. Imaging such as CT, MRI, and angiography is essential to guide decision-making and ensure patient safety.
