About Interventional Neuroradiology

Interventional neuroradiology, also known as neuro-interventional surgery, involves minimally invasive procedures to diagnose and treat conditions affecting the central nervous system. Utilizing advanced imaging techniques like angiography, interventional neuroradiologists navigate catheters and microcatheters through blood vessels to access the affected area. This approach allows for precise delivery of therapies such as clot retrieval for stroke, embolization for aneurysms, or stenting for narrowed arteries. Interventional neuroradiology offers patients less invasive treatment options with reduced risk and faster recovery compared to traditional surgery.

Types of Interventional Neuroradiology

  • Stroke Interventions: Including thrombectomy to remove blood clots obstructing brain vessels, crucial for acute ischemic stroke treatment.
  • Aneurysm Embolization: Minimally invasive closure of abnormal blood vessel bulges to prevent rupture, often using coils or liquid embolic agents.
  • Arteriovenous Malformation (AVM) Treatment: Embolization or occlusion techniques to manage abnormal connections between arteries and veins in the brain.
  • Carotid Artery Stenting: Placement of stents to widen and reinforce narrowed carotid arteries, reducing stroke risk.
  • Tumor Embolization: Pre-surgical or palliative embolization to reduce tumor blood supply, aiding in tumor resection or symptom management.

Why Do You Need Interventional Neuroradiology?

  • Minimally Invasive: Interventional neuroradiology offers less invasive alternatives to traditional surgery, reducing risks and recovery time.
  • Precision: Advanced imaging techniques enable precise navigation of catheters to target specific areas in the brain, minimizing damage to surrounding tissues.
  • Rapid Intervention: Immediate access to treatments like thrombectomy for stroke or aneurysm coiling can prevent permanent brain damage or hemorrhage.
  • Multidisciplinary Approach: Collaboration between neuroradiologists, neurosurgeons, and neurologists ensures comprehensive patient care.
  • Expanded Treatment Options: Interventional neuroradiology provides options for conditions previously considered untreatable or high-risk, improving outcomes for patients with complex neurological disorders.

What To Expect After An Interventional Neuroradiology? 
After interventional neuroradiology procedures, patients can expect close monitoring in a specialized recovery unit. Medical staff will observe for any immediate complications, such as bleeding or allergic reactions. Patients may experience mild discomfort at the catheter insertion site, which typically resolves quickly. Follow-up imaging scans may be scheduled to assess the effectiveness of the procedure. Depending on the specific intervention, patients may need to stay in the hospital for observation or be discharged home with instructions for post-procedure care. Overall, the goal is to ensure a smooth recovery and optimize the outcome of the intervention.

Frequently Asked Questions

Interventional Neuroradiology, also known as neuro-interventional radiology, is a medical speciality that uses minimally invasive procedures guided by imaging techniques to diagnose and treat disorders of the blood vessels in the brain and spine. This includes conditions such as aneurysms, arteriovenous malformations (AVMs), and stroke.

Common procedures in INR include endovascular coiling for aneurysms, embolization for AVMs, carotid and intracranial stenting, mechanical thrombectomy for stroke, and diagnostic angiography. These procedures are conducted using catheters, wires, and other devices guided through blood vessels with the assistance of medical imaging.

INR is recommended for various conditions such as acute stroke, vascular malformations, aneurysms, and certain types of tumors. It is particularly beneficial when traditional surgical approaches may pose higher risks or when a less invasive method is preferred to minimize patient recovery time.

An Interventional Neuroradiologist is a specialized physician who performs minimally invasive procedures to treat neurovascular disorders. They work closely with neurologists, neurosurgeons, and other specialists to determine the most suitable interventional approach for each patient, ensuring optimal outcomes with reduced risks.

Interventional Neuroradiology is generally considered safe, with a lower complication risk than traditional surgical approaches. However, as with any medical procedure, there are potential risks, including bleeding, infection, and allergic reactions. The specific risks depend on the type of procedure performed and the patient's overall health, and these aspects are thoroughly discussed with the patient before the intervention.
