When a brain scan reveals an abnormal blood vessel, aneurysm, vascular blockage, or another complex neurological condition, patients often need more than a routine neurological evaluation. Interventional neuroradiology combines advanced medical imaging with minimally invasive procedures to diagnose and treat selected conditions affecting the brain, spinal cord, and blood vessels.
For patients seeking an interventional neuroradiology specialist in Greater Kailash, the focus is usually on obtaining an accurate diagnosis and determining whether an image-guided procedure could be appropriate.
Interventional neuroradiology is a specialized area of medicine that uses real-time imaging to guide instruments through the body's blood vessels.
Instead of making a large surgical opening, a specialist can often access the vascular system through a small entry point and guide a catheter toward the area requiring treatment.
Depending on the condition, procedures may be used for:
The treatment approach depends on the patient's diagnosis and detailed imaging findings.
Brain Aneurysms
A brain aneurysm is a weakened section of a blood vessel that forms a bulge. Some aneurysms may be monitored, while others may require treatment.
Endovascular procedures such as coiling or flow diversion can be considered for selected aneurysms.
Ischemic Stroke
Some strokes occur when a blood clot blocks a major artery supplying the brain. In eligible patients, mechanical thrombectomy can be used to remove the clot and restore blood flow.
Because stroke can cause permanent brain injury, suspected stroke requires immediate emergency assessment.
Brain AVMs
An arteriovenous malformation is an abnormal connection between arteries and veins. Depending on its characteristics, an AVM may be treated using embolization, surgery, radiosurgery, or a combination of approaches.
Imaging is central to interventional neuroradiology.
Depending on the patient's condition, doctors may use:
These studies help reveal the structure and blood flow of vessels and allow specialists to plan procedures more precisely.
For complex vascular conditions, catheter-based angiography can provide detailed information that may not be available from routine brain imaging alone.
The exact procedure varies according to the condition being treated.
Generally, a catheter is introduced through a blood vessel, often through an access point in the wrist or groin. Using continuous imaging guidance, the specialist carefully navigates the catheter through the vascular system.
Specialized devices or materials may then be used to treat the abnormality.
For example, depending on the diagnosis, the procedure could involve:
An interventional neuroradiology specialist in Greater Kailash may be consulted when imaging identifies a cerebrovascular abnormality or when another doctor believes an endovascular treatment could be useful.
Patients may be referred after:
A referral does not automatically mean that a procedure will be performed. The specialist first determines whether intervention is appropriate.
One of the most important parts of neurovascular care is selecting the appropriate treatment rather than simply choosing the most advanced procedure available.
For example, an aneurysm may be suitable for observation, coiling, flow diversion, or another approach depending on its anatomy and the patient's circumstances.
Similarly, not every stroke patient qualifies for thrombectomy.
The specialist considers the patient's symptoms, imaging, timing, medical history, anatomy, and potential procedural risks before making a recommendation.
Patients can make their appointment more productive by bringing previous:
It is also useful to note when symptoms first appeared and whether they have changed over time.
When looking for an interventional neuroradiology specialist in Greater Kailash, consider whether the centre has advanced neuroimaging, an endovascular procedure facility, neurological monitoring, and access to related specialists such as neurologists and neurosurgeons.
For emergency conditions, particularly suspected stroke or brain hemorrhage, patients should seek immediate emergency medical care rather than waiting for a scheduled consultation.
1. What does an interventional neuroradiologist do?
An interventional neuroradiologist uses advanced imaging and minimally invasive techniques to diagnose and treat selected conditions involving the brain, spinal cord, and blood vessels.
2. Is interventional neuroradiology the same as neurosurgery?
They are different specialties, although they may work closely together. Interventional neuroradiology generally uses image-guided, catheter-based techniques, while neurosurgery can involve open surgical procedures as well as other specialized approaches.
3. Can an interventional neuroradiologist treat a brain aneurysm?
Selected aneurysms may be treated using endovascular techniques such as coiling or flow diversion. Whether treatment is appropriate depends on the aneurysm's characteristics and the patient's individual situation.
