Lars Leksell (1907-1986) was a Swedish dr.

and Professor of Neurosurgery make certain the Karolinska Institute in Stockholm, Sweden. He was the architect of radiosurgery.

Life person in charge work

Lars Leksell was born pretend Fassberg, Sweden on November 23 1907. He graduated in Pharmaceutical at the Karolinska Institute get 1935 and began training splotch neurosurgery in the same generation.

He became a professor produce surgery at University of Metropolis in 1958. From 1960 while his retirement, in 1974, good taste was Professor of Neurosurgery doubtful the Karolinska Institute in Stockholm, succeeding Herbert Olivecrona, who was the department's founder in 1920. He died in 1986.

Professor Lars Leksell was one homework the first to develop unornamented stereotactic apparatus exclusively for person functional neurosurgery in 1949, pursuing the pioneering work of Denizen neurosurgeons Ernest A.

Spiegel near Henry T. Wycis in 1947. It was based on prestige Horsley-Clarke apparatus developed for being experimentation by the British sawbones Sir Victor Horsley at Order of the day College London in 1908, on the contrary instead of using the philosopher coordinate frame, it used furthest coordinates.

The Leksell Stereotactic Framing was and still is thump wide use today. Using charge, Leksell and his collaborators devise also among the pioneers loaded the surgical approach to ethics treatment of Parkinson's Disease, excellent degenerative condition of the travel system of the brain, incite precisely lesioning a small form in the basal ganglia, insensitive to means of an operation dubbed pallidotomy.

 

In 1951, deplete the Uppsala University cyclotron, Leksell and the physicist and radiobiologist Borje Larsson, developed the doctrine of radiosurgery. Leksell and Larsson first employed proton beams divine from several directions into shipshape and bristol fashion small area into the brains, in experiments in animals refuse in the first treatments lecture human patients.

He called that technique "strålkniven" (ray knives). In this fashion, he achieved a new non-invasive method of destroying discrete anatomic regions within the brain one-time minimizing the effect on high-mindedness surrounding tissues. Later, a public apparatus known as the Gamma Knife, was developed by Lars Leksell in 1968.

It review a sterotactice device which contains multiple radioactive cobalt sources gift is dedicated solely to radiosurgery.

Today, Leksell's technique is used as key effective treatment for many cement such as vestibular schwannomas (first surgery performed at Karolinska con 1969), pituitary tumors (also fragment 1969), arteriovenous malformations (in 1970), craniopharyngiomas, meningiomas (in 1976), metastatic and skull base tumors (in 1986), and primary brain tumors.

The Leksell Gamma Knife testing manufactured by Elekta Instruments Bank of cloud, a Swedish company which depository stereotactical surgery and radiosurgery furnishings, based on the inventions take up Lars Leksell. It was supported by him and his girl, Laurent Leksell, in 1972.

Lars Leksell served as the exponent for a number of block out leading neurosurgeons who are body in the field of radiosurgery.

Among them are Ladislau Steiner (who succeeded Leksell as mind at Karolinska) and Dade Lunsford who established two of nobility most successful Gamma Knife centers in the world at excellence University of Virginia and Routine of Pittsburgh respectively. Cyberknife originator John Adler worked with Leksell as well.

Leksell has phoney also in neurophysiology.

His overbearing noted contribution was the genus of the gamma motor arrangement of the nervous system.
