[Combined treatment of cerebral arteriovenous malformations. Experience of the Burdenko Neurosurgical Institute].

OBJECTIVE: Despite the achievements of recent years, cerebral AVMs continue to pose a challenge to treatment. The objective of this work was the development of recommendations for combined treatment of AVMs based on analysis of the available material and published data. MATERIAL AND METHODS: The study included 93 patients hospitalized at the Neurosurgical Institute for combined treatment of cerebral AVMs in 2010-2014. A group of combined surgery (removal of an AVM with preoperative embolization) consisted of 40 patients, and a group of combined radiotherapy (radiation after partial embolization or partial removal of an AVM) included 53 patients. 36 patients underwent radiosurgery, and 17 patients received stereotactic radiation therapy. Both groups were analyzed in terms of outcomes, complications, and follow-up results. RESULTS: In the group of combined surgery, according to the Glasgow outcome scale, good results (grade 4-5) were achieved in 35 (87.5%) patients at discharge and in 27 (90%) patients during follow-up. Treatment outcomes, surgery duration, and the amount of blood loss were not significantly different from those in the control group. Complete AVM obliteration was achieved in 29 (80.6%) patients 3 years after radiosurgery and in 8 (47%) patients after stereotactic radiotherapy. In discussion, these findings are compared to the published data, and recommendations for AVM treatment are suggested. CONCLUSION: The combined treatment of AVMs is effective management for patients with complex AVMs (Spetzler-Martin grade III-IV AVMs). Successful treatment of AVMs requires careful planning and teamwork of vascular and endovascular neurosurgeons, radiologists, and neurologists.

[Intraoperative indocyanine green fluorescence angiography in surgery of brain aneurysms. The first experience with using the technique and literature review].

Intraoperative blood flow assessment after aneurysm clipping has become a standard procedure in vascular neurosurgery worldwide. Intraoperative indacyanine green angiography (ICG) has recently been certified in Russia. Fifteen patients with aneurysms operated with ICG control in Burdenko NSI are described in present publication. ICG advantages and weaknesses are discussed along with alternative flow control techniques available now.

[Working results of the electronic "on-line" version of the Spine Registry for Degenerative Lumbar Spine Diseases and study of its synchronization capacity with the electronic case history]. / Itogi raboty portal'noi versii poiasnichnogo vertebrologicheskogo registra i izuchenie voprosa ego sinkhronizatsii s élektronnoi istoriei bolezni.

AIM: To assess the results of use of lumbar spine on-line registry in 2012 (IV quarter). MATERIAL AND METHODS: The Burdenko Neurosurgery Institute of the Russian Academy of Medical Sciences (RAMS) and the System Analysis Institute of the Russian Academy of Sciences (RAS) have developed an electronic "on-line" portal of the Spine Registry for Degenerative Lumbar Spine Diseases. The data on 1295 retrospective and 145 prospective patients who underwent treatment in Burdenko Neurosurgery Institute, the "AXIS" clinic, Medical Centre of the Bank of Russia, "Marina Spine Clinic" LA, USA and in the Neurosurgery department of Research Institute of Traumatology and Orthopedics, Nizhny Novgorod were analyzed. Since May 2012 to the present time outcomes of 1295 (retrospective group) and 145 (prospective group) patients with Degenerative Lumbar Spine Diseases, which underwent treatment from 2002 to 2012 were entered into online registry and subsequently analyzed. The current study has revealed two problems that need to be discussed. First problem is that the archived information is not sufficient for data base update. The second problem is low activity of many physicians in inputting data into the register. We believe that the solution of these problems lies in the plane of synchronization of on-line registry with electronic medical records. This synchronization between registry and online records will allow studying their joint work. If found to be successful after the development of the other sections of the register they will be added to an already running version as provided by the principles of its work - scalability and extesibility. The results of this work will be profile of vertebrological version of electronic medical records. In the future it could be used in clinics dealing with spine disorders. RESULTS: Since May 2012 the outcomes of 1295 (retrospective group) and 145 (prospective group) patients with Degenerative Lumbar Spine Diseases, who were operated on in Burdenko Neurosurgery Institute (Moscow, Russia), minimally invasive spinal surgery clinic "AXIS" (Moscow, Russia), Medical Centre of The Bank of Russia (Moscow, Russia), "Marina Spine Clinic" (LA, USA) and Neurosurgery department of Research Institute of Traumatology and Orthopedics (Nizhny Novgorod, Russia) from 2002 to 2012 were analyzed. The perspective of this work is development of other parts of spine registry (for cervical and thoracic spine) and improving the outcome assessment process in Russian spinal surgery clinics.
