Interventional neuro radiology, also known as interventional neuroradiology or neurointerventional surgery, is a subspecialty of radiology that focuses on minimally invasive procedures for the diagnosis and treatment of various conditions affecting the brain, spine, and peripheral nervous system. INR procedures involve using image-guided techniques to access and treat conditions such as aneurysms, arteriovenous malformations, strokes, and tumors.
In interventional neuro radiology, several imaging techniques are used to guide the procedures and ensure accurate placement of devices or treatment. The most common imaging techniques include:
Digital subtraction angiography (DSA): This technique provides real-time visualization of blood vessels by injecting contrast material and capturing X-ray images.
Computed tomography (CT): CT scans are used to obtain detailed cross-sectional images of the brain, spine, and blood vessels.
Magnetic resonance imaging (MRI): MRI uses powerful magnets and radio waves to create detailed images of the brain, spine, and blood vessels without using ionizing radiation.
Fluoroscopy: Fluoroscopy is a real-time X-ray imaging technique that allows continuous visualization of the patient during procedures.
Interventional neuro radiology techniques can be used to diagnose and treat a variety of conditions, including:
Intracranial aneurysms: INR can be used to treat aneurysms by placing small metallic coils or stents to divert blood flow away from the aneurysm and prevent rupture.
Arteriovenous malformations (AVMs): AVMs are abnormal tangles of blood vessels. INR procedures can involve embolization, where a substance is injected into the AVM to block blood flow and reduce the risk of bleeding.
Acute ischemic stroke: INR techniques such as mechanical thrombectomy can be employed to remove blood clots causing strokes and restore blood flow to the affected area.
Tumors: INR can aid in the diagnosis and treatment of brain and spinal tumors by delivering targeted chemotherapy, embolizing blood vessels supplying the tumor, or assisting with biopsy procedures.
Interventional neuro radiology offers several advantages over traditional open surgery, including:
Minimally invasive: INR procedures are typically performed through small incisions or using catheters, resulting in less tissue damage, reduced pain, and shorter recovery times.
Lower risk: INR procedures generally carry a lower risk of complications compared to open surgery, as they avoid large incisions and general anesthesia.
Faster recovery: The minimally invasive nature of INR allows for quicker recovery times, shorter hospital stays, and earlier return to normal activities.
Improved precision: INR procedures are guided by advanced imaging techniques, enabling precise targeting of the affected area and reducing the risk of damage to surrounding structures.
If you're scheduled for an interventional neuro radiology procedure, your healthcare team will provide specific instructions tailored to your case. However, some general preparations may include:
Fasting: You may be required to avoid eating or drinking for a certain period before the procedure, especially if contrast material will be used.
Medication adjustments: Inform your healthcare team about any medications you're taking, as some may need to be adjusted or temporarily stopped before the procedure.
Allergies: If you have any known allergies, particularly to contrast material or medications, inform your doctor
