What is interventional neuroradilogy (or endovascular neurosurgery)?
Interventional neuroradilogy (or endovascular neurosurgery) is a hybrid specialty that has recently evolved to diagnose and treat a range of neurological diseases. Using x-ray guidance small catheters are guided into the blood vessels of the neck and brain enabling a range of diagnostic and therapeutic interventions.
What conditions are treatable with interventional neuroradiology (or endovascular neurosurgery)?
Interventional neuroradilogy (or endovascular neurosurgery )uses cerebral angiography to diagnose a variety of pathologies, including:
Occlusions of intracranial vessels leading to impaired cerebral blood flow and stroke.
Once these conditions are diagnosed they may be treated using a variety of techniques, for example:
Tumors of the brain spinal column can be devascularized by embolization procedures.
Aneurysms can be occluded using detachable coils and stents when appropriate.
The blood supply to vascular malformations can be reduced with embolization.
Stents can be deployed to treat stenosis of the carotid arteries.
Lastly intravascular thrombolysis can be used to dissolve blood clots in the major cerebral vessels that are causing stroke.
Frequently neurointerventional procedures are employed as part of a larger treatment plan that incorporates traditional open surgical methods. For example, a brain tumor may be devascularized using neurointerventional techniques prior to surgical resection.
