Interventional neuroradiology (or endovascular neurosurgery), is practiced by specialty trained neuroradiologists, neurosurgeons and neurologists, utilizing an endovascular approach to treat vascular diseases of the central nervous system. These diseases include aneurysms, arteriovenous malformations (AVMs) and stroke in the adult and pediatric populations.
Since the emergence of interventional neuroradiology more than four decades ago, technological advances have led to progress in scientific knowledge and the development of highly efficient endovascular devices allowing for a better understanding and identification of the vascular lesions that may be treated. The endovascular devices are introduced through catheters in the peripheral blood vessels and advanced to the vascular abnormality in the brain or spine. Once in position, they can be used to block abnormalities within the vessels to protect from hemorrhage or to open up blocked arteries to improve the blood flow. Coils, liquid embolic materials, stents and clot retrieval devices are examples of therapeutic devices commonly used by interventional neuroradiologists.
Interventional neuroradiology is also involved in the treatment of traumatic lesions in the head and neck region, pre-operative devascularization of tumors and other vascular masses, as well as in percutaneous spinal procedures like augmentation of vertebral compression fractures.
UNC Interventional Neuroradiology is part of an Award-Winning Comprehensive Stroke Center which received the American Heart Association/ American Stroke Association Gold Plus Award. Time to treatment is a very important factor for stroke patients. We are able to transfer stroke patients from the emergency room to the procedure room and remove clots from blood vessel in the brain within 30 minutes of arrival at UNC.
The division of Interventional Neuroradiology also works closely with the UNC Hereditary Hemorrhagic Telangiectasia Center of Excellence to study and treat this specific type of vascular malformations. In addition, we are part of a UNC multidisciplinary team focusing on education, research and treatment of vascular malformations in children and adults
UNC is pleased to have one of the most experienced neuro-interventional teams in the region. Drs. Sten Solander and Hortensia Alvarez have more than 50 years of combined experience in treating neurovascular diseases in adults and children. With the most recent addition of Dr. Deanna Sasaki-Adams to the team (UNC Neurosurgery/UNC Radiology joint faculty), we are able to offer the best treatment options based upon the specific needs for each individual patient. This experience along with a team of neurosurgeons, neurologists and the neuro-intensive care specialists, makes UNC particularly strong in the field of interventional neuroradiology/endovascular neurosurgery.
