What is interventional neuroradiology?
Interventional neuroradiology is a specialty dedicated to procedures that diagnose and treat disorders of the blood vessels of the neck and brain (cerebrovascular disease), spine, head and neck. It's also called endovascular neurosurgery because most procedures are performed through blood vessels rather than through open surgery. These procedures are often performed using catheters (narrow hollow tubes) and image-guided techniques.
Just as minimally-invasive surgery is a growing trend in medicine, more patients with neurovascular disorders are now being treated by endovascular or other image-guided, less-invasive techniques that shorten recovery times. Common procedures performed by interventional neuroradiologists include treating cerebral aneurysms using coils or flow diverter devices, treating arteriovenous malformtions or fistulas by injecting a liquid glue or polymer, treating arteries narrowed by atherosclerotic plaque by dilating stenoses with balloons or stents, and reducing the blood supply to tumor or bleeding sites by blocking the involved blood vessels through catheter techniques.
