A cerebral arteriovenous malformation is an abnormal connection between the arteries and veins in the brain—specifically, an arteriovenous malformation in the cerebrum.
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty concerned with the surgical treatment of disorders which affect any portion of the nervous system including the brain, spinal cord and peripheral nervous system.
An intracranial aneurysm, also known as a cerebral aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel.
The International Subarachnoid Aneurysm Trial (ISAT) was a large multicentre, prospective randomised clinical medical trial, comparing the safety and efficacy of endovascular coil treatment and surgical clipping for the treatment of brain aneurysms. The study began in 1994. The first results were published in The Lancet in 2002, and the 10 year data were published again in The Lancet in early September 2005. 2,143 study participants were mostly drawn from U.K. hospitals with the rest drawn from North American and European hospitals.
Joshua B. Bederson is an American neurosurgeon, Leonard I. Malis, MD/Corinne and Joseph Graber Professor of Neurosurgery, and System Chair of Neurosurgery at the Mount Sinai Health System in New York City. He is a Fellow of the American College of Surgeons, and an attending neurosurgeon at The Mount Sinai Hospital.
Vein of Galen aneurysmal malformations(VGAMs) and Vein of Galen aneurysmal dilations (VGADs) are the most frequent arteriovenous malformations in infants and fetuses. A VGAM consists of a tangled mass of dilated vessels supplied by an enlarged artery. The malformation increases greatly in size with age, although the mechanism of the increase is unknown. Dilation of the great cerebral vein of Galen is a secondary result of the force of arterial blood either directly from an artery via an arteriovenous fistula or by way of a tributary vein that receives the blood directly from an artery. There is usually a venous anomaly downstream from the draining vein that, together with the high blood flow into the great cerebral vein of Galen causes its dilation. The right sided cardiac chambers and pulmonary arteries also develop mild to severe dilation.
Barrow Neurological Institute is the world's largest neurological disease treatment and research institution, and is consistently ranked as one of the best neurosurgical training centers in the United States. Founded in 1962, the main campus is located at 350 W. Thomas Road, Phoenix, Arizona.
Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM. Despite its designation as a hemangioma, a cavernous hemangioma is not a tumor as it does not display endothelial hyperplasia. The abnormal tissue causes a slowing of blood flow through the cavities, or "caverns". The blood vessels do not form the necessary junctions with surrounding cells, and the structural support from the smooth muscle is hindered, causing leakage into the surrounding tissue. It is the leakage of blood, referred to as hemorrhage, that causes a variety of symptoms known to be associated with the condition.
Aaron A. Cohen-Gadol is a professor of neurological surgery in the department of neurosurgery at Indiana University School of Medicine and a neurosurgeon at Indiana University Health specializing in the surgical treatment of complex brain tumors, vascular malformations, cavernous malformations, etc. He performs removal of brain tumors via minimally invasive endoscopic techniques, which use the nasal pathways instead of opening the skull.
Curtis Dickman is an American researcher, author, and retired Neurosurgeon. He is recognized internationally for his pioneering work in the fields of Spinal Surgery, Surgery of the Craniocervical Junction, Spinal Biomechanics, and Thoracoscopic Neurosurgery.
Interventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head, neck, and spine.

Robert Wheeler Rand, was an American neurosurgeon, inventor, and Professor of Neurosurgery in the Department of Neurosurgery at the University of California Los Angeles (UCLA) from 1953 to 1989.
Antonio Bernardo is an Italian-American neurosurgeon and academic physician. He is a professor of Neurological Surgery and the Director of the Neurosurgical Innovations and Training Center for Skull Base and Microneurosurgery in the Department of Neurological Surgery at Weill Cornell Medical College. He has gained significant notoriety for his expertise in skull base and cerebrovascular surgery, and has published extensively on minimally invasive neurosurgery. He is a pioneer in the use of 3D technology in neurosurgery and a strong advocate for competency-based training in surgery.

Alexander Coon is an American neurosurgeon who is the Director of Endovascular and Cerebrovascular Neurosurgery at the Carondelet Neurological Institute of St. Joseph's and St. Mary's Hospitals in Tucson, Arizona. He was previously the Director of Endovascular Neurosurgery at the Johns Hopkins Hospital and an assistant professor of neurosurgery, Neurology, and Radiology at the Johns Hopkins Hospital. He is known for his work in cerebrovascular and endovascular neurosurgery and his research in neuroendovascular devices and clinical outcomes in the treatment of cerebral aneurysms, subarachnoid hemorrhage, and AVMs.
Claire Karekezi is a Neurosurgeon at the Rwanda Military Hospital in Kigali, Rwanda. As the first woman neurosurgeon in Rwanda, and one of eight neurosurgeons serving a population of 13 million, Karekezi serves as an advocate for women in neurosurgery.
