Navigation in vascular neurosurgery [Primenenie navigatsii v sosudistoi neirokhirurgii]
No full textLiterature review is devoted to the role of frameless neuronavigation in surgery of distal aneurysms, cavernomas, arteriovenous malformations, Kimmerle's anomaly and revascularization surgeries. Visualization methods used in preoperative preparation of patients with vascular lesions compatible with frameless neuronavigation and the methods of intraoperative visualization as an addition to navigation are described.Приведен анализ данных научной литературы о роли безрамной нейронавигации в хирургии дистальных аневризм, каверном и артериовенозных мальформаций головного мозга, а также при аномалии Киммерле и реваскуляризирующих операциях. Описаны методы визуализации, используемые в качестве предоперационной подготовки пациентов с сосудистой патологией, совместимые с безрамной нейронавигацией, и методы интраоперационной визуализации, применяемые в качестве дополнения к навигации
Resection of a giant fusiform aneurysm of the pericallosal artery with «hemi-bonnet bypass» procedure (Case report and literature review)
No full textA 30-year-old woman with giant fusiform aneurysm of the azygos anterior cerebral artery is reported. Clipping of the aneurysm followed by modeling of pericallosal artery was performed in 2017. However, further enlargement of the aneurysm has been observed for subsequent 2 years. The patient underwent redo surgery with excision of the aneurysm followed by «hemi-bonnet bypass» procedure (anastomosis between superficial temporal artery and anterior cerebral artery with radial artery as an interposition graft). Literature data on reconstructive surgery in the treatment of complex pericallosal artery aneurysms are reviewed. © 2020, Media Sphera Publishing Group. All rights reserved
Microsurgical treatment of distal aneurysms of the middle cerebral artery [МИКРОХИРУРГИЧЕСКОЕ ЛЕЧЕНИЕ ДИСТАЛЬНЫХ АНЕВРИЗМ СРЕДНЕЙ МОЗГОВОЙ АРТЕРИИ]
No full textThe study objective is to investigate the features of distal aneurysms of the middle cerebral artery and to evaluate the results of their surgical treatment. Materials and methods. From 01 / 01 / 2000 to 12 / 31 / 2019 at the N. V. Sklifosovsky Research Institute of Emergency Medicine, 37 patients with distal SMA aneurysms were operated (21 women, 16 men, the average age of 48 y. o). SMA aneurysms were classified by their localization according to the classification of H. Gibo. The aneurysms of the M2 segment of the MCA were encountered more often (56.8 %). 28 aneurysms had a saccular structure, 9 (24.3 %) had a fusiform. The size of the saccular aneurysms ranged from 1.4 to 34.0 mm. More than 65 % of patients had aneurysms of 7 mm or less. Results. The surgical access was selected depending on the location of the MCA aneurysm. The pterional transsylvian access is used more often, less often - with aneurysms of the M4-segment, convexital trepanation. The reconstructive clipping of the distal SMA aneurysm was performed in 22 (59.4 %) cases, trapping and / or excision in 15 (40.5 %) cases. After the deconstructive intervention, revascularization was performed on 6 (16 %) patients. Conclusion. Distal aneurysms of the middle cerebral artery are a rare pathology that requires an individual approach - contact Doppler ultrasound or intraoperative angiography, intraoperative neuromonitoring, as well as, if necessary, the use of revascularization methods. To optimize surgical access, it is preferable to use neuronavigation. © 2021 Russian Journal of Neurosurgery. All rights reserved
