To the memory of Professor Tigliev Georgy Samuilovich

(to the 70th anniversary of his birth)

 

Professor Tigliev Georgy Samuilovich would have been 70 on November 9, 2003.

However, the invisible force, known as fate, issued its own decree and this brilliant person, who was one of the outstanding Russian neurosurgeons, Honored Science Worker, professor and head of the Neurooncologic Department at the Polenov Research Neurosurgical Institute, died of a severe disease on November 19, 2002.

Tigliev G.S. was born in Simferopol on November 9, 1933. His father was an employee. When a boy, Tigliev had to experience all adversities and difficulties, which fell on the wartime generation.

He entered the Tomsk Medical Institute in 1953.

After graduation (1959) Tigliev G.S. was sent to the regional traumatologic hospital of Prokopyevsk (a small town in Siberia), where he worked during four years. At first, he was a doctor in charge in a neurosurgical department. In 1961 Tigliev took a specialization course at the Chair of Neurosurgery of the Leningrad Institute of Advanced Medical Training. After it he became a head of the department of the above hospital and junior researcher in the affiliate of the Novosibirsk Research Institute of Traumatology and Orthopedics. At the same time Tigliev worked as a not-on-permanent-staff head neurosurgeon of the Kemerovskaya region (Siberia).

In 1963 he began to attend a postgraduate course in neurosurgery on the recommendation of Professor Ugryumov V.M., where he studied up to 1966. After defending his thesis for a Candidate's degree, entitled Changes of Dermal and Rectal Temperature in Patients Operated for Brain Tumors, Tigliev G.S. was assigned to work at the Polenov Research Neurosurgical Institute by the Ministry of Public Health of the Russian Federation.

In 1966-1969 Tigliev G.S. was a junior researcher of this Institute; in 1969-1975 he filled a post of a scientific secretary. Tigliev G.S. headed the Neurooncologic Department of the above Institute up to the last day of his life.

He became a Doctor of Medical Science in 1981 after defending his thesis for a Doctor's degree. Its title was Disorders of Local Cerebral Blood Flow in Surgery of Vascular Aneurysms and Brain Tumors: Neurogenic Factors. In 1989 Tigliev was given an academic status of a professor-neurosurgeon by the All-Union Attestation Commission.

The results of his original studies, which can be regarded as further development of ideas of the Petersburg neurosurgical and physiologic schools, were presented in Regulation of Cerebral Circulation (1984), written together with Professor Ugryumov V.M. and Teplov S.I.

In 1984-1987 Tigliev G.S. was the Institute Director and Neurosurgeon-in-Chief of the Russian Ministry of Public Health. Order N 108 on organization of neurosurgical care in Russia, issued by the Russian Ministry of Public Health in 1987 and being still valid today, was prepared under his guidance and with his active participation.

In the middle of the 70s Tigliev began to develop and introduce microsurgical technique of interventions for brain tumors not only in his Institute, but also in other Russian medical establishments. He got several patents and author's certificates on surgical approaches to structures of the posterior cranial fossa, chiasm-cellar region as well as methods of brain revascularization and removal of meningioma of cerebellum tentorium, epilepsy treatment, etc.

Tigliev G.S. had 27 certificates and patents on different inventions, among which there are several methods of neurosurgical operations and devices, used during them. One of the most important inventions was his original microsurgical microscope, whose modifications had been a target of his persistent creative activity for more than 25 years (video).

In 1988 Tigliev G.S. was elected a writing member of the Saint Petersburg Technical Academy for development of original optic devices.

In 1996 he became the Honored Science Worker of the Russian Federation.

The main trends of research, carried out by Tigliev G.S. and his coworkers, were as follows: development of approaches, tactics and microsurgical devices (a surgery microscope, intraoperative head holders, poly-functional microsurgical instruments), study of cerebral circulation disorders, multimodality therapy of glial tumors.

Tigliev G.S. was one of the leading Russian specialists in the field of neurosurgery in general and neurooncology in particular. He often visited different regions of the country with the purpose of consulting and making operations. Besides, Tigliev G.S. delivered lectures, made reports and organized seminars for neurosurgeons. Recommendations for practical public health, worked out under his guidance, are important clinical textbooks on surgery of the CNS tumors.

Tigliev G.S. is an author of more than 200 works, devoted to different problems of neurosurgery. In 1997 there appeared his monograph Surgery of Intracranial Extracerebral Tumors. As for Intracranial Meningiomas, published in 2001, it was the first monograph in Russia (after the book by K.G. Terian, 1941), elucidating this pathology. It was highly appreciated by Russian neurosurgeons.

Tigliev G.S. was a member of the following organizations: two neurosurgical councils, dealing with defense and approval of theses for a Doctor's degree; the Editorial Board of such journals as Voprosy Neirokhirurgii and Russian Neurosurgery; the Neurosurgical Associations of Saint Petersburg and Russia, the European and World Associations of Neurosurgeons. He became a member of the Cushing Association of Neurologic Surgeons (USA) in 1984 on the initiative of American neurosurgeons. Tigliev G.S. was an honorary member of the Moscow Neurosurgical Society (2001).

He participated in exhibitions of neurosurgical equipment in Chicago (1994), Berlin (1995), Saint Petersburg (1995, 1996, 1997). Tigliev G.S. got diplomas at several Saint Petersburg exhibitions and the All-Union Exhibition of Achievements of National Economy.

It should be mentioned, that 5 theses for a Doctor's and 18 theses for a Candidate's Degree, approved by the All-Union Attestation Commission, were written and defended under the guidance of professor G.S. Tigliev. He made a rather great contribution into formation of the Neurooncologic Department. Thanks to his activity, today it has all necessary equipment for microsurgery, anesthesiologic support and clinical-physiologic monitoring of vital systems, permitting to treat patients with craniobasal tumors, to ensure maximum preservation of cerebral structures and, what is more important, to improve quality of their lives.

Scientific achievements of G.S. Tigliev have been described in medical literature and are well-known; their novelty is confirmed by patents; his operating microscope for neurosurgeons has gone into batch production.
