Danielpour M, von Koch C, S, Ojemann S, G, Peacock W, J, Disconnective Hemispherectomy. Hemispherectomy was first tried on a dog in 1888 by Friedrich Goltz. Likewise, hemispherectomy likely would be recommended to a patient with debilitating seizures. In this procedure, the surgeon aims to disconnect (rather than remove) the hemisphere, hence termed hemispherotomy, in order to minimize long term complications. A study in 2007 indicated the long-term efficacy of anatomic hemispherectomy in carefully selected adults, with seizure control sustainable over multiple decades. Walter Dandy MD 1886-1946 The Surgical Innovations • 1921- Removal of tumors • 1922- Endoscopy for RX hydrocephalus • 1925- Section CN5 for trig neuralgia • 1929- Removal of herniated disc • 1930--Surg RX spasmodic torticollis • 1933- Hemispherectomy for malignant tumors • 1933-Removal of deep tumors in ventricular system. Historical Vignette. Walter Dandy completed the first hemispherectomy in 1928 when he attempted radical resection of a glioblastoma. The most notable case is that of Ahad Israfil, who lost the right side of his cerebrum in 1987 in a gun-related work accident. [13][14], Because of the dramatic alteration of brain composition and the inherent risk that hemispherectomies pose, there are criteria that must be met in order for a person to qualify for the procedure. Walter Dandy more or less pioneered hemispherectomy in an attempt to treat glioblastoma in the first half of the 20th Century. [11][12] Another procedure relatively new to epilepsy surgery is endoscopic surgery (see endoscopy), surgery performed using small camera scopes and little incision sites. Additionally, it is also known to often markedly improve the cognitive functioning and development of the individual. "Dynamic Development of the Hemispheric Biases in Three Cases: Cognitive/Hemispheric Cycles, Music, and Hemispherectomy." About one in three patients with epilepsy will continue to have persistent seizures despite epileptic drug therapy. Although several patients died shortly after their operation, this fact did not damper this pioneer's enthusiasm. Dandy made a number important contributions to neurosurgery. He is considered one of the founding fathers of neurosurgery, along with Victor Horsley (1857–1916) and Harvey Cushing (1869–1939). Hemispherectomy was first performed on a dog in 1888 by Friedrich Goltz. Hemispherectomy was revitalized in children in the 1980s by John M. Freeman and Ben Carson[5] at Johns Hopkins Hospital. in 1923 by Dr. Walter Dandy.1 It was reported ... Hemispherectomy is the most successful operation for the control of seizures in a very select group of patients with [19] In 2012, a case study following 30 individuals having undergone some form of hemispherectomy in adulthood found that 81% of individuals were seizure free post-procedure. This procedure is used to treat a variety of seizure disorders where the source of the epilepsy is localized to a broad area of a single hemisphere of the brain, notably Rasmussen's encephalitis. Ed. Choi, Charles. A second type of hemispherectomy, known as functional hemispherectomy, has become more prevalent in recent years. [1] Hemispherectomy is reserved for the most extreme cases of this one-third in which the individual’s seizures are irresponsive to medications or other less invasive surgeries and significantly impair functioning or put the patient at risk of further complications. This patient eventually developed "superior language and intellectual abilities" despite the removal of the left hemisphere, which contains the classical language zones.[25]. The operation hemispherectomy, or hemicorticectomy as linguistic purists prefer to describe it, has waxed and waned in usage periodically since it was reported independently by Walter Dandy (1928) and by L'Hermitte (1928) as a dramatic effort to cure patients with malignant gliomas of the cerebral hemisphere. 21 Sept. 2016. U.S. National Library of Medicine, May 2013. Neurosurgery: The Register of the Neurosurgical Meme. Walter Dandy first performed the latter operation for treatment of malignant gliomas in 1928, and hemispherectomy for treatment of epilepsy was first reported in 1938.
