====== 1951 ====== [[1950]]-[[1952]] [[Diencephalic syndrome]] was first described by Russell in [[1951]]. ---- In [[1951]], using the [[Uppsala]] University cyclotron, [[Lars Leksell]] and the physicist and radiobiologist Borje Larsson, developed the concept of [[Radiosurgery]]. ---- In [[1951]], Basset reported the first successful surgical resection of an [[Arteriovenous malformation of the corpus callosum]] ((BASSETT RC. Surgical experiences with arteriovenous anomalies of the brain. J Neurosurg. 1951 Jan;8(1):59-74. PubMed PMID: 14804149. )). ---- Even though since the end of the 19th century the spinal CSF pressure was used as indirect measure of [[intracranial pressure]] (ICP), the first reports of the use of continuous [[intracranial pressure monitoring]] via [[ventricular catheter]] were by Guillaume and Janny in [[1951]] ((Guillaume J, Janny P. Continuous intracranial manometry; importance of the method and first. Revue Neurologique. 1951;84(2):131–142.)). ---- [[Endarterectomy]] was first performed on a superficial [[femoral artery]] in [[1946]] by the Portuguese surgeon João Cid dos Santos at the University of [[Lisbon]]. In [[1951]], E. J. Wylie, an American, performed it on the abdominal aorta. The first successful reconstruction of the [[carotid artery]] was performed by Carrea, Molins, and Murphy in Argentina, later in the same year. ---- The [[Congress of Neurological Surgeons]] was founded on May 10, [[1951]]. Since [[1951]], the [[Annual Meeting of the Congress of Neurological Surgeons]] has been an [[event]] to unite membership at one location. This collaboration of [[neurosurgeon]]s and honored guests have a rich history.
